GIT-CONFIG(1) Git Manual GIT-CONFIG(1) NAME git-config - Get and set repository or global options SYNOPSIS git config [] [--type=] [--comment=] [--fixed-value] [--show-origin] [--show-scope] [-z|--null] [ []] git config [] [--type=] [--comment=] --add git config [] [--type=] [--comment=] [--fixed-value] --replace-all [] git config [] [--type=] [--show-origin] [--show-scope] [-z|--null] [--fixed-value] --get [] git config [] [--type=] [--show-origin] [--show-scope] [-z|--null] [--fixed-value] --get-all [] git config [] [--type=] [--show-origin] [--show-scope] [-z|--null] [--fixed-value] [--name-only] --get-regexp [] git config [] [--type=] [-z|--null] --get-urlmatch git config [] [--fixed-value] --unset [] git config [] [--fixed-value] --unset-all [] git config [] --rename-section git config [] --remove-section git config [] [--show-origin] [--show-scope] [-z|--null] [--name-only] -l | --list git config [] --get-color [] git config [] --get-colorbool [] git config [] -e | --edit DESCRIPTION You can query/set/replace/unset options with this command. The name is actually the section and the key separated by a dot, and the value will be escaped. Multiple lines can be added to an option by using the --add option. If you want to update or unset an option which can occur on multiple lines, a value-pattern (which is an extended regular expression, unless the --fixed-value option is given) needs to be given. Only the existing values that match the pattern are updated or unset. If you want to handle the lines that do not match the pattern, just prepend a single exclamation mark in front (see also the section called "EXAMPLES"), but note that this only works when the --fixed-value option is not in use. The --type= option instructs git config to ensure that incoming and outgoing values are canonicalize-able under the given . If no --type= is given, no canonicalization will be performed. Callers may unset an existing --type specifier with --no-type. When reading, the values are read from the system, global and repository local configuration files by default, and options --system, --global, --local, --worktree and --file can be used to tell the command to read from only that location (see the section called "FILES"). When writing, the new value is written to the repository local configuration file by default, and options --system, --global, --worktree, --file can be used to tell the command to write to that location (you can say --local but that is the default). This command will fail with non-zero status upon error. Some exit codes are: o The section or key is invalid (ret=1), o no section or name was provided (ret=2), o the config file is invalid (ret=3), o the config file cannot be written (ret=4), o you try to unset an option which does not exist (ret=5), o you try to unset/set an option for which multiple lines match (ret=5), or o you try to use an invalid regexp (ret=6). On success, the command returns the exit code 0. A list of all available configuration variables can be obtained using the git help --config command. OPTIONS --replace-all Default behavior is to replace at most one line. This replaces all lines matching the key (and optionally the value-pattern). --add Adds a new line to the option without altering any existing values. This is the same as providing ^$ as the value-pattern in --replace-all. --comment Append a comment at the end of new or modified lines. If __ begins with one or more whitespaces followed by "#", it is used as-is. If it begins with "#", a space is prepended before it is used. Otherwise, a string " # " (a space followed by a hash followed by a space) is prepended to it. And the resulting string is placed immediately after the value defined for the variable. The __ must not contain linefeed characters (no multi-line comments are permitted). --get Get the value for a given key (optionally filtered by a regex matching the value). Returns error code 1 if the key was not found and the last value if multiple key values were found. --get-all Like get, but returns all values for a multi-valued key. --get-regexp Like --get-all, but interprets the name as a regular expression and writes out the key names. Regular expression matching is currently case-sensitive and done against a canonicalized version of the key in which section and variable names are lowercased, but subsection names are not. --get-urlmatch When given a two-part as
., the value for
.. whose part matches the best to the given URL is returned (if no such key exists, the value for
. is used as a fallback). When given just the
as name, do so for all the keys in the section and list them. Returns error code 1 if no value is found. --global For writing options: write to global ~/.gitconfig file rather than the repository .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the ~/.gitconfig file doesn't. For reading options: read only from global ~/.gitconfig and from $XDG_CONFIG_HOME/git/config rather than from all available files. See also the section called "FILES". --system For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository .git/config. For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than from all available files. See also the section called "FILES". --local For writing options: write to the repository .git/config file. This is the default behavior. For reading options: read only from the repository .git/config rather than from all available files. See also the section called "FILES". --worktree Similar to --local except that $GIT_DIR/config.worktree is read from or written to if extensions.worktreeConfig is enabled. If not it's the same as --local. Note that $GIT_DIR is equal to $GIT_COMMON_DIR for the main working tree, but is of the form $GIT_DIR/worktrees// for other working trees. See git- worktree(1) to learn how to enable extensions.worktreeConfig. -f , --file For writing options: write to the specified file rather than the repository .git/config. For reading options: read only from the specified file rather than from all available files. See also the section called "FILES". --blob Similar to --file but use the given blob instead of a file. E.g. you can use master:.gitmodules to read values from the file .gitmodules in the master branch. See "SPECIFYING REVISIONS" section in gitrevisions(7) for a more complete list of ways to spell blob names. --remove-section Remove the given section from the configuration file. --rename-section Rename the given section to a new name. --unset Remove the line matching the key from config file. --unset-all Remove all lines matching the key from config file. -l, --list List all variables set in config file, along with their values. --fixed-value When used with the value-pattern argument, treat value-pattern as an exact string instead of a regular expression. This will restrict the name/value pairs that are matched to only those where the value is exactly equal to the value-pattern. --type git config will ensure that any input or output is valid under the given type constraint(s), and will canonicalize outgoing values in 's canonical form. Valid 's include: o bool: canonicalize values as either "true" or "false". o int: canonicalize values as simple decimal numbers. An optional suffix of k, m, or g will cause the value to be multiplied by 1024, 1048576, or 1073741824 upon input. o bool-or-int: canonicalize according to either bool or int, as described above. o path: canonicalize by expanding a leading ~ to the value of $HOME and ~user to the home directory for the specified user. This specifier has no effect when setting the value (but you can use git config section.variable ~/ from the command line to let your shell do the expansion.) o expiry-date: canonicalize by converting from a fixed or relative date-string to a timestamp. This specifier has no effect when setting the value. o color: When getting a value, canonicalize by converting to an ANSI color escape sequence. When setting a value, a sanity-check is performed to ensure that the given value is canonicalize-able as an ANSI color, but it is written as-is. --bool, --int, --bool-or-int, --path, --expiry-date Historical options for selecting a type specifier. Prefer instead --type (see above). --no-type Un-sets the previously set type specifier (if one was previously set). This option requests that git config not canonicalize the retrieved variable. --no-type has no effect without --type= or --. -z, --null For all options that output values and/or keys, always end values with the null character (instead of a newline). Use newline instead as a delimiter between key and value. This allows for secure parsing of the output without getting confused e.g. by values that contain line breaks. --name-only Output only the names of config variables for --list or --get-regexp. --show-origin Augment the output of all queried config options with the origin type (file, standard input, blob, command line) and the actual origin (config file path, ref, or blob id if applicable). --show-scope Similar to --show-origin in that it augments the output of all queried config options with the scope of that value (worktree, local, global, system, command). --get-colorbool [] Find the color setting for (e.g. color.diff) and output "true" or "false". should be either "true" or "false", and is taken into account when configuration says "auto". If is missing, then checks the standard output of the command itself, and exits with status 0 if color is to be used, or exits with status 1 otherwise. When the color setting for name is undefined, the command uses color.ui as fallback. --get-color [] Find the color configured for name (e.g. color.diff.new) and output it as the ANSI color escape sequence to the standard output. The optional default parameter is used instead, if there is no color configured for name. --type=color [--default=] is preferred over --get-color (but note that --get-color will omit the trailing newline printed by --type=color). -e, --edit Opens an editor to modify the specified config file; either --system, --global, --local (default), --worktree, or --file . --[no-]includes Respect include.* directives in config files when looking up values. Defaults to off when a specific file is given (e.g., using --file, --global, etc) and on when searching all config files. --default When using --get, and the requested variable is not found, behave as if were the value assigned to that variable. CONFIGURATION pager.config is only respected when listing configuration, i.e., when using --list or any of the --get-* which may return multiple results. The default is to use a pager. FILES By default, git config will read configuration options from multiple files: $(prefix)/etc/gitconfig System-wide configuration file. $XDG_CONFIG_HOME/git/config, ~/.gitconfig User-specific configuration files. When the XDG_CONFIG_HOME environment variable is not set or empty, $HOME/.config/ is used as $XDG_CONFIG_HOME. These are also called "global" configuration files. If both files exist, both files are read in the order given above. $GIT_DIR/config Repository specific configuration file. $GIT_DIR/config.worktree This is optional and is only searched when extensions.worktreeConfig is present in $GIT_DIR/config. You may also provide additional configuration parameters when running any git command by using the -c option. See git(1) for details. Options will be read from all of these files that are available. If the global or the system-wide configuration files are missing or unreadable they will be ignored. If the repository configuration file is missing or unreadable, git config will exit with a non-zero error code. An error message is produced if the file is unreadable, but not if it is missing. The files are read in the order given above, with last value found taking precedence over values read earlier. When multiple values are taken then all values of a key from all files will be used. By default, options are only written to the repository specific configuration file. Note that this also affects options like --replace-all and --unset. git config will only ever change one file at a time. You can limit which configuration sources are read from or written to by specifying the path of a file with the --file option, or by specifying a configuration scope with --system, --global, --local, or --worktree. For more, see the section called "OPTIONS" above. SCOPES Each configuration source falls within a configuration scope. The scopes are: system $(prefix)/etc/gitconfig global $XDG_CONFIG_HOME/git/config ~/.gitconfig local $GIT_DIR/config worktree $GIT_DIR/config.worktree command GIT_CONFIG_{COUNT,KEY,VALUE} environment variables (see the section called "ENVIRONMENT" below) the -c option With the exception of command, each scope corresponds to a command line option: --system, --global, --local, --worktree. When reading options, specifying a scope will only read options from the files within that scope. When writing options, specifying a scope will write to the files within that scope (instead of the repository specific configuration file). See the section called "OPTIONS" above for a complete description. Most configuration options are respected regardless of the scope it is defined in, but some options are only respected in certain scopes. See the respective option's documentation for the full details. Protected configuration Protected configuration refers to the system, global, and command scopes. For security reasons, certain options are only respected when they are specified in protected configuration, and ignored otherwise. Git treats these scopes as if they are controlled by the user or a trusted administrator. This is because an attacker who controls these scopes can do substantial harm without using Git, so it is assumed that the user's environment protects these scopes against attackers. ENVIRONMENT GIT_CONFIG_GLOBAL, GIT_CONFIG_SYSTEM Take the configuration from the given files instead from global or system-level configuration. See git(1) for details. GIT_CONFIG_NOSYSTEM Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file. See git(1) for details. See also the section called "FILES". GIT_CONFIG_COUNT, GIT_CONFIG_KEY_, GIT_CONFIG_VALUE_ If GIT_CONFIG_COUNT is set to a positive number, all environment pairs GIT_CONFIG_KEY_ and GIT_CONFIG_VALUE_ up to that number will be added to the process's runtime configuration. The config pairs are zero-indexed. Any missing key or value is treated as an error. An empty GIT_CONFIG_COUNT is treated the same as GIT_CONFIG_COUNT=0, namely no pairs are processed. These environment variables will override values in configuration files, but will be overridden by any explicit options passed via git -c. This is useful for cases where you want to spawn multiple git commands with a common configuration but cannot depend on a configuration file, for example when writing scripts. GIT_CONFIG If no --file option is provided to git config, use the file given by GIT_CONFIG as if it were provided via --file. This variable has no effect on other Git commands, and is mostly for historical compatibility; there is generally no reason to use it instead of the --file option. EXAMPLES Given a .git/config like this: # # This is the config file, and # a '#' or ';' character indicates # a comment # ; core variables [core] ; Don't trust file modes filemode = false ; Our diff algorithm [diff] external = /usr/local/bin/diff-wrapper renames = true ; Proxy settings [core] gitproxy=proxy-command for kernel.org gitproxy=default-proxy ; for all the rest ; HTTP [http] sslVerify [http "https://weak.example.com"] sslVerify = false cookieFile = /tmp/cookie.txt you can set the filemode to true with % git config core.filemode true The hypothetical proxy command entries actually have a postfix to discern what URL they apply to. Here is how to change the entry for kernel.org to "ssh". % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$' This makes sure that only the key/value pair for kernel.org is replaced. To delete the entry for renames, do % git config --unset diff.renames If you want to delete an entry for a multivar (like core.gitproxy above), you have to provide a regex matching the value of exactly one line. To query the value for a given key, do % git config --get core.filemode or % git config core.filemode or, to query a multivar: % git config --get core.gitproxy "for kernel.org$" If you want to know all the values for a multivar, do: % git config --get-all core.gitproxy If you like to live dangerously, you can replace all core.gitproxy by a new one with % git config --replace-all core.gitproxy ssh However, if you really only want to replace the line for the default proxy, i.e. the one without a "for ..." postfix, do something like this: % git config core.gitproxy ssh '! for ' To actually match only values with an exclamation mark, you have to % git config section.key value '[!]' To add a new proxy, without altering any of the existing ones, use % git config --add core.gitproxy '"proxy-command" for example.com' An example to use customized color from the configuration in your script: #!/bin/sh WS=$(git config --get-color color.diff.whitespace "blue reverse") RESET=$(git config --get-color "" "reset") echo "${WS}your whitespace color or blue reverse${RESET}" For URLs in https://weak.example.com, http.sslVerify is set to false, while it is set to true for all others: % git config --type=bool --get-urlmatch http.sslverify https://good.example.com true % git config --type=bool --get-urlmatch http.sslverify https://weak.example.com false % git config --get-urlmatch http https://weak.example.com http.cookieFile /tmp/cookie.txt http.sslverify false CONFIGURATION FILE The Git configuration file contains a number of variables that affect the Git commands' behavior. The files .git/config and optionally config.worktree (see the "CONFIGURATION FILE" section of git- worktree(1)) in each repository are used to store the configuration for that repository, and $HOME/.gitconfig is used to store a per-user configuration as fallback values for the .git/config file. The file /etc/gitconfig can be used to store a system-wide default configuration. The configuration variables are used by both the Git plumbing and the porcelain commands. The variables are divided into sections, wherein the fully qualified variable name of the variable itself is the last dot-separated segment and the section name is everything before the last dot. The variable names are case-insensitive, allow only alphanumeric characters and -, and must start with an alphabetic character. Some variables may appear multiple times; we say then that the variable is multivalued. Syntax The syntax is fairly flexible and permissive. Whitespace characters, which in this context are the space character (SP) and the horizontal tabulation (HT), are mostly ignored. The # and ; characters begin comments to the end of line. Blank lines are ignored. The file consists of sections and variables. A section begins with the name of the section in square brackets and continues until the next section begins. Section names are case-insensitive. Only alphanumeric characters, - and . are allowed in section names. Each variable must belong to some section, which means that there must be a section header before the first setting of a variable. Sections can be further divided into subsections. To begin a subsection put its name in double quotes, separated by space from the section name, in the section header, like in the example below: [section "subsection"] Subsection names are case sensitive and can contain any characters except newline and the null byte. Doublequote " and backslash can be included by escaping them as \" and \\, respectively. Backslashes preceding other characters are dropped when reading; for example, \t is read as t and \0 is read as 0. Section headers cannot span multiple lines. Variables may belong directly to a section or to a given subsection. You can have [section] if you have [section "subsection"], but you don't need to. There is also a deprecated [section.subsection] syntax. With this syntax, the subsection name is converted to lower-case and is also compared case sensitively. These subsection names follow the same restrictions as section names. All the other lines (and the remainder of the line after the section header) are recognized as setting variables, in the form name = value (or just name, which is a short-hand to say that the variable is the boolean "true"). The variable names are case-insensitive, allow only alphanumeric characters and -, and must start with an alphabetic character. Whitespace characters surrounding name, = and value are discarded. Internal whitespace characters within value are retained verbatim. Comments starting with either # or ; and extending to the end of line are discarded. A line that defines a value can be continued to the next line by ending it with a backslash (\); the backslash and the end-of-line characters are discarded. If value needs to contain leading or trailing whitespace characters, it must be enclosed in double quotation marks ("). Inside double quotation marks, double quote (") and backslash (\) characters must be escaped: use \" for " and \\ for \. The following escape sequences (beside \" and \\) are recognized: \n for newline character (NL), \t for horizontal tabulation (HT, TAB) and \b for backspace (BS). Other char escape sequences (including octal escape sequences) are invalid. Includes The include and includeIf sections allow you to include config directives from another source. These sections behave identically to each other with the exception that includeIf sections may be ignored if their condition does not evaluate to true; see "Conditional includes" below. You can include a config file from another by setting the special include.path (or includeIf.*.path) variable to the name of the file to be included. The variable takes a pathname as its value, and is subject to tilde expansion. These variables can be given multiple times. The contents of the included file are inserted immediately, as if they had been found at the location of the include directive. If the value of the variable is a relative path, the path is considered to be relative to the configuration file in which the include directive was found. See below for examples. Conditional includes You can conditionally include a config file from another by setting an includeIf..path variable to the name of the file to be included. The condition starts with a keyword followed by a colon and some data whose format and meaning depends on the keyword. Supported keywords are: gitdir The data that follows the keyword gitdir: is used as a glob pattern. If the location of the .git directory matches the pattern, the include condition is met. The .git location may be auto-discovered, or come from $GIT_DIR environment variable. If the repository is auto-discovered via a .git file (e.g. from submodules, or a linked worktree), the .git location would be the final location where the .git directory is, not where the .git file is. The pattern can contain standard globbing wildcards and two additional ones, **/ and /**, that can match multiple path components. Please refer to gitignore(5) for details. For convenience: o If the pattern starts with ~/, ~ will be substituted with the content of the environment variable HOME. o If the pattern starts with ./, it is replaced with the directory containing the current config file. o If the pattern does not start with either ~/, ./ or /, **/ will be automatically prepended. For example, the pattern foo/bar becomes **/foo/bar and would match /any/path/to/foo/bar. o If the pattern ends with /, ** will be automatically added. For example, the pattern foo/ becomes foo/**. In other words, it matches "foo" and everything inside, recursively. gitdir/i This is the same as gitdir except that matching is done case-insensitively (e.g. on case-insensitive file systems) onbranch The data that follows the keyword onbranch: is taken to be a pattern with standard globbing wildcards and two additional ones, **/ and /**, that can match multiple path components. If we are in a worktree where the name of the branch that is currently checked out matches the pattern, the include condition is met. If the pattern ends with /, ** will be automatically added. For example, the pattern foo/ becomes foo/**. In other words, it matches all branches that begin with foo/. This is useful if your branches are organized hierarchically and you would like to apply a configuration to all the branches in that hierarchy. hasconfig:remote.*.url: The data that follows this keyword is taken to be a pattern with standard globbing wildcards and two additional ones, **/ and /**, that can match multiple components. The first time this keyword is seen, the rest of the config files will be scanned for remote URLs (without applying any values). If there exists at least one remote URL that matches this pattern, the include condition is met. Files included by this option (directly or indirectly) are not allowed to contain remote URLs. Note that unlike other includeIf conditions, resolving this condition relies on information that is not yet known at the point of reading the condition. A typical use case is this option being present as a system-level or global-level config, and the remote URL being in a local-level config; hence the need to scan ahead when resolving this condition. In order to avoid the chicken-and-egg problem in which potentially-included files can affect whether such files are potentially included, Git breaks the cycle by prohibiting these files from affecting the resolution of these conditions (thus, prohibiting them from declaring remote URLs). As for the naming of this keyword, it is for forwards compatibility with a naming scheme that supports more variable-based include conditions, but currently Git only supports the exact keyword described above. A few more notes on matching via gitdir and gitdir/i: o Symlinks in $GIT_DIR are not resolved before matching. o Both the symlink & realpath versions of paths will be matched outside of $GIT_DIR. E.g. if ~/git is a symlink to /mnt/storage/git, both gitdir:~/git and gitdir:/mnt/storage/git will match. This was not the case in the initial release of this feature in v2.13.0, which only matched the realpath version. Configuration that wants to be compatible with the initial release of this feature needs to either specify only the realpath version, or both versions. o Note that "../" is not special and will match literally, which is unlikely what you want. Example # Core variables [core] ; Don't trust file modes filemode = false # Our diff algorithm [diff] external = /usr/local/bin/diff-wrapper renames = true [branch "devel"] remote = origin merge = refs/heads/devel # Proxy settings [core] gitProxy="ssh" for "kernel.org" gitProxy=default-proxy ; for the rest [include] path = /path/to/foo.inc ; include by absolute path path = foo.inc ; find "foo.inc" relative to the current file path = ~/foo.inc ; find "foo.inc" in your `$HOME` directory ; include if $GIT_DIR is /path/to/foo/.git [includeIf "gitdir:/path/to/foo/.git"] path = /path/to/foo.inc ; include for all repositories inside /path/to/group [includeIf "gitdir:/path/to/group/"] path = /path/to/foo.inc ; include for all repositories inside $HOME/to/group [includeIf "gitdir:~/to/group/"] path = /path/to/foo.inc ; relative paths are always relative to the including ; file (if the condition is true); their location is not ; affected by the condition [includeIf "gitdir:/path/to/group/"] path = foo.inc ; include only if we are in a worktree where foo-branch is ; currently checked out [includeIf "onbranch:foo-branch"] path = foo.inc ; include only if a remote with the given URL exists (note ; that such a URL may be provided later in a file or in a ; file read after this file is read, as seen in this example) [includeIf "hasconfig:remote.*.url:https://example.com/**"] path = foo.inc [remote "origin"] url = https://example.com/git Values Values of many variables are treated as a simple string, but there are variables that take values of specific types and there are rules as to how to spell them. boolean When a variable is said to take a boolean value, many synonyms are accepted for true and false; these are all case-insensitive. true Boolean true literals are yes, on, true, and 1. Also, a variable defined without = is taken as true. false Boolean false literals are no, off, false, 0 and the empty string. When converting a value to its canonical form using the --type=bool type specifier, git config will ensure that the output is "true" or "false" (spelled in lowercase). integer The value for many variables that specify various sizes can be suffixed with k, M,... to mean "scale the number by 1024", "by 1024x1024", etc. color The value for a variable that takes a color is a list of colors (at most two, one for foreground and one for background) and attributes (as many as you want), separated by spaces. The basic colors accepted are normal, black, red, green, yellow, blue, magenta, cyan, white and default. The first color given is the foreground; the second is the background. All the basic colors except normal and default have a bright variant that can be specified by prefixing the color with bright, like brightred. The color normal makes no change to the color. It is the same as an empty string, but can be used as the foreground color when specifying a background color alone (for example, "normal red"). The color default explicitly resets the color to the terminal default, for example to specify a cleared background. Although it varies between terminals, this is usually not the same as setting to "white black". Colors may also be given as numbers between 0 and 255; these use ANSI 256-color mode (but note that not all terminals may support this). If your terminal supports it, you may also specify 24-bit RGB values as hex, like #ff0ab3. The accepted attributes are bold, dim, ul, blink, reverse, italic, and strike (for crossed-out or "strikethrough" letters). The position of any attributes with respect to the colors (before, after, or in between), doesn't matter. Specific attributes may be turned off by prefixing them with no or no- (e.g., noreverse, no-ul, etc). The pseudo-attribute reset resets all colors and attributes before applying the specified coloring. For example, reset green will result in a green foreground and default background without any active attributes. An empty color string produces no color effect at all. This can be used to avoid coloring specific elements without disabling color entirely. For git's pre-defined color slots, the attributes are meant to be reset at the beginning of each item in the colored output. So setting color.decorate.branch to black will paint that branch name in a plain black, even if the previous thing on the same output line (e.g. opening parenthesis before the list of branch names in log --decorate output) is set to be painted with bold or some other attribute. However, custom log formats may do more complicated and layered coloring, and the negated forms may be useful there. pathname A variable that takes a pathname value can be given a string that begins with "~/" or "~user/", and the usual tilde expansion happens to such a string: ~/ is expanded to the value of $HOME, and ~user/ to the specified user's home directory. If a path starts with %(prefix)/, the remainder is interpreted as a path relative to Git's "runtime prefix", i.e. relative to the location where Git itself was installed. For example, %(prefix)/bin/ refers to the directory in which the Git executable itself lives. If Git was compiled without runtime prefix support, the compiled-in prefix will be substituted instead. In the unlikely event that a literal path needs to be specified that should not be expanded, it needs to be prefixed by ./, like so: ./%(prefix)/bin. Variables Note that this list is non-comprehensive and not necessarily complete. For command-specific variables, you will find a more detailed description in the appropriate manual page. Other git-related tools may and do use their own variables. When inventing new variables for use in your own tool, make sure their names do not conflict with those that are used by Git itself and other popular tools, and describe them in your documentation. add.ignoreErrors, add.ignore-errors (deprecated) Tells git add to continue adding files when some files cannot be added due to indexing errors. Equivalent to the --ignore-errors option of git-add(1). add.ignore-errors is deprecated, as it does not follow the usual naming convention for configuration variables. add.interactive.useBuiltin Unused configuration variable. Used in Git versions v2.25.0 to v2.36.0 to enable the built-in version of git-add(1)'s interactive mode, which then became the default in Git versions v2.37.0 to v2.39.0. advice.* These variables control various optional help messages designed to aid new users. When left unconfigured, Git will give the message alongside instructions on how to squelch it. You can tell Git that you do not need the help message by setting these to false: addEmbeddedRepo Shown when the user accidentally adds one git repo inside of another. addEmptyPathspec Shown when the user runs git add without providing the pathspec parameter. addIgnoredFile Shown when the user attempts to add an ignored file to the index. amWorkDir Shown when git-am(1) fails to apply a patch file, to tell the user the location of the file. ambiguousFetchRefspec Shown when a fetch refspec for multiple remotes maps to the same remote-tracking branch namespace and causes branch tracking set-up to fail. checkoutAmbiguousRemoteBranchName Shown when the argument to git-checkout(1) and git-switch(1) ambiguously resolves to a remote tracking branch on more than one remote in situations where an unambiguous argument would have otherwise caused a remote-tracking branch to be checked out. See the checkout.defaultRemote configuration variable for how to set a given remote to be used by default in some situations where this advice would be printed. commitBeforeMerge Shown when git-merge(1) refuses to merge to avoid overwriting local changes. detachedHead Shown when the user uses git-switch(1) or git-checkout(1) to move to the detached HEAD state, to tell the user how to create a local branch after the fact. diverging Shown when a fast-forward is not possible. fetchShowForcedUpdates Shown when git-fetch(1) takes a long time to calculate forced updates after ref updates, or to warn that the check is disabled. forceDeleteBranch Shown when the user tries to delete a not fully merged branch without the force option set. ignoredHook Shown when a hook is ignored because the hook is not set as executable. implicitIdentity Shown when the user's information is guessed from the system username and domain name, to tell the user how to set their identity configuration. mergeConflict Shown when various commands stop because of conflicts. nestedTag Shown when a user attempts to recursively tag a tag object. pushAlreadyExists Shown when git-push(1) rejects an update that does not qualify for fast-forwarding (e.g., a tag.) pushFetchFirst Shown when git-push(1) rejects an update that tries to overwrite a remote ref that points at an object we do not have. pushNeedsForce Shown when git-push(1) rejects an update that tries to overwrite a remote ref that points at an object that is not a commit-ish, or make the remote ref point at an object that is not a commit-ish. pushNonFFCurrent Shown when git-push(1) fails due to a non-fast-forward update to the current branch. pushNonFFMatching Shown when the user ran git-push(1) and pushed "matching refs" explicitly (i.e. used :, or specified a refspec that isn't the current branch) and it resulted in a non-fast-forward error. pushRefNeedsUpdate Shown when git-push(1) rejects a forced update of a branch when its remote-tracking ref has updates that we do not have locally. pushUnqualifiedRefname Shown when git-push(1) gives up trying to guess based on the source and destination refs what remote ref namespace the source belongs in, but where we can still suggest that the user push to either refs/heads/* or refs/tags/* based on the type of the source object. pushUpdateRejected Set this variable to false if you want to disable pushNonFFCurrent, pushNonFFMatching, pushAlreadyExists, pushFetchFirst, pushNeedsForce, and pushRefNeedsUpdate simultaneously. refSyntax Shown when the user provides an illegal ref name, to tell the user about the ref syntax documentation. resetNoRefresh Shown when git-reset(1) takes more than 2 seconds to refresh the index after reset, to tell the user that they can use the --no-refresh option. resolveConflict Shown by various commands when conflicts prevent the operation from being performed. rmHints Shown on failure in the output of git-rm(1), to give directions on how to proceed from the current state. sequencerInUse Shown when a sequencer command is already in progress. skippedCherryPicks Shown when git-rebase(1) skips a commit that has already been cherry-picked onto the upstream branch. statusAheadBehind Shown when git-status(1) computes the ahead/behind counts for a local ref compared to its remote tracking ref, and that calculation takes longer than expected. Will not appear if status.aheadBehind is false or the option --no-ahead-behind is given. statusHints Show directions on how to proceed from the current state in the output of git-status(1), in the template shown when writing commit messages in git-commit(1), and in the help message shown by git-switch(1) or git-checkout(1) when switching branches. statusUoption Shown when git-status(1) takes more than 2 seconds to enumerate untracked files, to tell the user that they can use the -u option. submoduleAlternateErrorStrategyDie Shown when a submodule.alternateErrorStrategy option configured to "die" causes a fatal error. submoduleMergeConflict Advice shown when a non-trivial submodule merge conflict is encountered. submodulesNotUpdated Shown when a user runs a submodule command that fails because git submodule update --init was not run. suggestDetachingHead Shown when git-switch(1) refuses to detach HEAD without the explicit --detach option. updateSparsePath Shown when either git-add(1) or git-rm(1) is asked to update index entries outside the current sparse checkout. waitingForEditor Shown when Git is waiting for editor input. Relevant when e.g. the editor is not launched inside the terminal. worktreeAddOrphan Shown when the user tries to create a worktree from an invalid reference, to tell the user how to create a new unborn branch instead. alias.* Command aliases for the git(1) command wrapper - e.g. after defining alias.last = cat-file commit HEAD, the invocation git last is equivalent to git cat-file commit HEAD. To avoid confusion and troubles with script usage, aliases that hide existing Git commands are ignored. Arguments are split by spaces, the usual shell quoting and escaping are supported. A quote pair or a backslash can be used to quote them. Note that the first word of an alias does not necessarily have to be a command. It can be a command-line option that will be passed into the invocation of git. In particular, this is useful when used with -c to pass in one-time configurations or -p to force pagination. For example, loud-rebase = -c commit.verbose=true rebase can be defined such that running git loud-rebase would be equivalent to git -c commit.verbose=true rebase. Also, ps = -p status would be a helpful alias since git ps would paginate the output of git status where the original command does not. If the alias expansion is prefixed with an exclamation point, it will be treated as a shell command. For example, defining alias.new = !gitk --all --not ORIG_HEAD, the invocation git new is equivalent to running the shell command gitk --all --not ORIG_HEAD. Note that shell commands will be executed from the top-level directory of a repository, which may not necessarily be the current directory. GIT_PREFIX is set as returned by running git rev-parse --show-prefix from the original current directory. See git-rev- parse(1). am.keepcr If true, git-am will call git-mailsplit for patches in mbox format with parameter --keep-cr. In this case git-mailsplit will not remove \r from lines ending with \r\n. Can be overridden by giving --no-keep-cr from the command line. See git-am(1), git- mailsplit(1). am.threeWay By default, git am will fail if the patch does not apply cleanly. When set to true, this setting tells git am to fall back on 3-way merge if the patch records the identity of blobs it is supposed to apply to and we have those blobs available locally (equivalent to giving the --3way option from the command line). Defaults to false. See git-am(1). apply.ignoreWhitespace When set to change, tells git apply to ignore changes in whitespace, in the same way as the --ignore-space-change option. When set to one of: no, none, never, false, it tells git apply to respect all whitespace differences. See git-apply(1). apply.whitespace Tells git apply how to handle whitespace, in the same way as the --whitespace option. See git-apply(1). attr.tree A reference to a tree in the repository from which to read attributes, instead of the .gitattributes file in the working tree. In a bare repository, this defaults to HEAD:.gitattributes. If the value does not resolve to a valid tree object, an empty tree is used instead. When the GIT_ATTR_SOURCE environment variable or --attr-source command line option are used, this configuration variable has no effect. blame.blankBoundary Show blank commit object name for boundary commits in git-blame(1). This option defaults to false. blame.coloring This determines the coloring scheme to be applied to blame output. It can be repeatedLines, highlightRecent, or none which is the default. blame.date Specifies the format used to output dates in git-blame(1). If unset the iso format is used. For supported values, see the discussion of the --date option at git-log(1). blame.showEmail Show the author email instead of author name in git-blame(1). This option defaults to false. blame.showRoot Do not treat root commits as boundaries in git-blame(1). This option defaults to false. blame.ignoreRevsFile Ignore revisions listed in the file, one unabbreviated object name per line, in git-blame(1). Whitespace and comments beginning with # are ignored. This option may be repeated multiple times. Empty file names will reset the list of ignored revisions. This option will be handled before the command line option --ignore-revs-file. blame.markUnblamableLines Mark lines that were changed by an ignored revision that we could not attribute to another commit with a * in the output of git- blame(1). blame.markIgnoredLines Mark lines that were changed by an ignored revision that we attributed to another commit with a ? in the output of git- blame(1). branch.autoSetupMerge Tells git branch, git switch and git checkout to set up new branches so that git-pull(1) will appropriately merge from the starting point branch. Note that even if this option is not set, this behavior can be chosen per-branch using the --track and --no-track options. The valid settings are: false -- no automatic setup is done; true -- automatic setup is done when the starting point is a remote-tracking branch; always -- automatic setup is done when the starting point is either a local branch or remote-tracking branch; inherit -- if the starting point has a tracking configuration, it is copied to the new branch; simple -- automatic setup is done only when the starting point is a remote-tracking branch and the new branch has the same name as the remote branch. This option defaults to true. branch.autoSetupRebase When a new branch is created with git branch, git switch or git checkout that tracks another branch, this variable tells Git to set up pull to rebase instead of merge (see "branch..rebase"). When never, rebase is never automatically set to true. When local, rebase is set to true for tracked branches of other local branches. When remote, rebase is set to true for tracked branches of remote-tracking branches. When always, rebase will be set to true for all tracking branches. See "branch.autoSetupMerge" for details on how to set up a branch to track another branch. This option defaults to never. branch.sort This variable controls the sort ordering of branches when displayed by git-branch(1). Without the "--sort=" option provided, the value of this variable will be used as the default. See git-for- each-ref(1) field names for valid values. branch..remote When on branch , it tells git fetch and git push which remote to fetch from or push to. The remote to push to may be overridden with remote.pushDefault (for all branches). The remote to push to, for the current branch, may be further overridden by branch..pushRemote. If no remote is configured, or if you are not on any branch and there is more than one remote defined in the repository, it defaults to origin for fetching and remote.pushDefault for pushing. Additionally, . (a period) is the current local repository (a dot-repository), see branch..merge's final note below. branch..pushRemote When on branch , it overrides branch..remote for pushing. It also overrides remote.pushDefault for pushing from branch . When you pull from one place (e.g. your upstream) and push to another place (e.g. your own publishing repository), you would want to set remote.pushDefault to specify the remote to push to for all branches, and use this option to override it for a specific branch. branch..merge Defines, together with branch..remote, the upstream branch for the given branch. It tells git fetch/git pull/git rebase which branch to merge and can also affect git push (see push.default). When in branch , it tells git fetch the default refspec to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a refspec, and must match a ref which is fetched from the remote given by "branch..remote". The merge information is used by git pull (which first calls git fetch) to lookup the default branch for merging. Without this option, git pull defaults to merge the first refspec fetched. Specify multiple values to get an octopus merge. If you wish to setup git pull so that it merges into from another branch in the local repository, you can point branch..merge to the desired branch, and use the relative path setting . (a period) for branch..remote. branch..mergeOptions Sets default options for merging into branch . The syntax and supported options are the same as those of git-merge(1), but option values containing whitespace characters are currently not supported. branch..rebase When true, rebase the branch on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. See "pull.rebase" for doing this in a non branch-specific manner. When merges (or just m), pass the --rebase-merges option to git rebase so that the local merge commits are included in the rebase (see git-rebase(1) for details). When the value is interactive (or just i), the rebase is run in interactive mode. NOTE: this is a possibly dangerous operation; do not use it unless you understand the implications (see git-rebase(1) for details). branch..description Branch description, can be edited with git branch --edit-description. Branch description is automatically added to the format-patch cover letter or request-pull summary. browser..cmd Specify the command to invoke the specified browser. The specified command is evaluated in shell with the URLs passed as arguments. (See git-web--browse(1).) browser..path Override the path for the given tool that may be used to browse HTML help (see -w option in git-help(1)) or a working repository in gitweb (see git-instaweb(1)). bundle.* The bundle.* keys may appear in a bundle list file found via the git clone --bundle-uri option. These keys currently have no effect if placed in a repository config file, though this will change in the future. See the bundle URI design document[1] for more details. bundle.version This integer value advertises the version of the bundle list format used by the bundle list. Currently, the only accepted value is 1. bundle.mode This string value should be either all or any. This value describes whether all of the advertised bundles are required to unbundle a complete understanding of the bundled information (all) or if any one of the listed bundle URIs is sufficient (any). bundle.heuristic If this string-valued key exists, then the bundle list is designed to work well with incremental git fetch commands. The heuristic signals that there are additional keys available for each bundle that help determine which subset of bundles the client should download. The only value currently understood is creationToken. bundle..* The bundle..* keys are used to describe a single item in the bundle list, grouped under for identification purposes. bundle..uri This string value defines the URI by which Git can reach the contents of this . This URI may be a bundle file or another bundle list. checkout.defaultRemote When you run git checkout or git switch and only have one remote, it may implicitly fall back on checking out and tracking e.g. origin/. This stops working as soon as you have more than one remote with a reference. This setting allows for setting the name of a preferred remote that should always win when it comes to disambiguation. The typical use-case is to set this to origin. Currently this is used by git-switch(1) and git-checkout(1) when git checkout or git switch will checkout the branch on another remote, and by git-worktree(1) when git worktree add refers to a remote branch. This setting might be used for other checkout-like commands or functionality in the future. checkout.guess Provides the default value for the --guess or --no-guess option in git checkout and git switch. See git-switch(1) and git-checkout(1). checkout.workers The number of parallel workers to use when updating the working tree. The default is one, i.e. sequential execution. If set to a value less than one, Git will use as many workers as the number of logical cores available. This setting and checkout.thresholdForParallelism affect all commands that perform checkout. E.g. checkout, clone, reset, sparse-checkout, etc. Note: Parallel checkout usually delivers better performance for repositories located on SSDs or over NFS. For repositories on spinning disks and/or machines with a small number of cores, the default sequential checkout often performs better. The size and compression level of a repository might also influence how well the parallel version performs. checkout.thresholdForParallelism When running parallel checkout with a small number of files, the cost of subprocess spawning and inter-process communication might outweigh the parallelization gains. This setting allows you to define the minimum number of files for which parallel checkout should be attempted. The default is 100. clean.requireForce A boolean to make git-clean refuse to delete files unless -f is given. Defaults to true. clone.defaultRemoteName The name of the remote to create when cloning a repository. Defaults to origin. It can be overridden by passing the --origin command-line option to git-clone(1). clone.rejectShallow Reject cloning a repository if it is a shallow one; this can be overridden by passing the --reject-shallow option on the command line. See git-clone(1). clone.filterSubmodules If a partial clone filter is provided (see --filter in git-rev- list(1)) and --recurse-submodules is used, also apply the filter to submodules. color.advice A boolean to enable/disable color in hints (e.g. when a push failed, see advice.* for a list). May be set to always, false (or never) or auto (or true), in which case colors are used only when the error output goes to a terminal. If unset, then the value of color.ui is used (auto by default). color.advice.hint Use customized color for hints. color.blame.highlightRecent Specify the line annotation color for git blame --color-by-age depending upon the age of the line. This setting should be set to a comma-separated list of color and date settings, starting and ending with a color, the dates should be set from oldest to newest. The metadata will be colored with the specified colors if the line was introduced before the given timestamp, overwriting older timestamped colors. Instead of an absolute timestamp relative timestamps work as well, e.g. 2.weeks.ago is valid to address anything older than 2 weeks. It defaults to blue,12 month ago,white,1 month ago,red, which colors everything older than one year blue, recent changes between one month and one year old are kept white, and lines introduced within the last month are colored red. color.blame.repeatedLines Use the specified color to colorize line annotations for git blame --color-lines, if they come from the same commit as the preceding line. Defaults to cyan. color.branch A boolean to enable/disable color in the output of git-branch(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. If unset, then the value of color.ui is used (auto by default). color.branch. Use customized color for branch coloration. is one of current (the current branch), local (a local branch), remote (a remote-tracking branch in refs/remotes/), upstream (upstream tracking branch), plain (other refs). color.diff Whether to use ANSI escape sequences to add color to patches. If this is set to always, git-diff(1), git-log(1), and git-show(1) will use color for all patches. If it is set to true or auto, those commands will only use color when output is to the terminal. If unset, then the value of color.ui is used (auto by default). This does not affect git-format-patch(1) or the git-diff-* plumbing commands. Can be overridden on the command line with the --color[=] option. color.diff. Use customized color for diff colorization. specifies which part of the patch to use the specified color, and is one of context (context text - plain is a historical synonym), meta (metainformation), frag (hunk header), func (function in hunk header), old (removed lines), new (added lines), commit (commit headers), whitespace (highlighting whitespace errors), oldMoved (deleted lines), newMoved (added lines), oldMovedDimmed, oldMovedAlternative, oldMovedAlternativeDimmed, newMovedDimmed, newMovedAlternative newMovedAlternativeDimmed (See the setting of --color-moved in git-diff(1) for details), contextDimmed, oldDimmed, newDimmed, contextBold, oldBold, and newBold (see git-range-diff(1) for details). color.decorate. Use customized color for git log --decorate output. is one of branch, remoteBranch, tag, stash or HEAD for local branches, remote-tracking branches, tags, stash and HEAD, respectively and grafted for grafted commits. color.grep When set to always, always highlight matches. When false (or never), never. When set to true or auto, use color only when the output is written to the terminal. If unset, then the value of color.ui is used (auto by default). color.grep. Use customized color for grep colorization. specifies which part of the line to use the specified color, and is one of context non-matching text in context lines (when using -A, -B, or -C) filename filename prefix (when not using -h) function function name lines (when using -p) lineNumber line number prefix (when using -n) column column number prefix (when using --column) match matching text (same as setting matchContext and matchSelected) matchContext matching text in context lines matchSelected matching text in selected lines. Also, used to customize the following git-log(1) subcommands: --grep, --author, and --committer. selected non-matching text in selected lines. Also, used to customize the following git-log(1) subcommands: --grep, --author and --committer. separator separators between fields on a line (:, -, and =) and between hunks (--) color.interactive When set to always, always use colors for interactive prompts and displays (such as those used by "git-add --interactive" and "git-clean --interactive"). When false (or never), never. When set to true or auto, use colors only when the output is to the terminal. If unset, then the value of color.ui is used (auto by default). color.interactive. Use customized color for git add --interactive and git clean --interactive output. may be prompt, header, help or error, for four distinct types of normal output from interactive commands. color.pager A boolean to specify whether auto color modes should colorize output going to the pager. Defaults to true; set this to false if your pager does not understand ANSI color codes. color.push A boolean to enable/disable color in push errors. May be set to always, false (or never) or auto (or true), in which case colors are used only when the error output goes to a terminal. If unset, then the value of color.ui is used (auto by default). color.push.error Use customized color for push errors. color.remote If set, keywords at the start of the line are highlighted. The keywords are "error", "warning", "hint" and "success", and are matched case-insensitively. May be set to always, false (or never) or auto (or true). If unset, then the value of color.ui is used (auto by default). color.remote. Use customized color for each remote keyword. may be hint, warning, success or error which match the corresponding keyword. color.showBranch A boolean to enable/disable color in the output of git-show- branch(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. If unset, then the value of color.ui is used (auto by default). color.status A boolean to enable/disable color in the output of git-status(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. If unset, then the value of color.ui is used (auto by default). color.status. Use customized color for status colorization. is one of header (the header text of the status message), added or updated (files which are added but not committed), changed (files which are changed but not added in the index), untracked (files which are not tracked by Git), branch (the current branch), nobranch (the color the no branch warning is shown in, defaulting to red), localBranch or remoteBranch (the local and remote branch names, respectively, when branch and tracking information is displayed in the status short-format), or unmerged (files which have unmerged changes). color.transport A boolean to enable/disable color when pushes are rejected. May be set to always, false (or never) or auto (or true), in which case colors are used only when the error output goes to a terminal. If unset, then the value of color.ui is used (auto by default). color.transport.rejected Use customized color when a push was rejected. color.ui This variable determines the default value for variables such as color.diff and color.grep that control the use of color per command family. Its scope will expand as more commands learn configuration to set a default for the --color option. Set it to false or never if you prefer Git commands not to use color unless enabled explicitly with some other configuration or the --color option. Set it to always if you want all output not intended for machine consumption to use color, to true or auto (this is the default since Git 1.8.4) if you want such output to use color when written to the terminal. column.ui Specify whether supported commands should output in columns. This variable consists of a list of tokens separated by spaces or commas: These options control when the feature should be enabled (defaults to never): always always show in columns never never show in columns auto show in columns if the output is to the terminal These options control layout (defaults to column). Setting any of these implies always if none of always, never, or auto are specified. column fill columns before rows row fill rows before columns plain show in one column Finally, these options can be combined with a layout option (defaults to nodense): dense make unequal size columns to utilize more space nodense make equal size columns column.branch Specify whether to output branch listing in git branch in columns. See column.ui for details. column.clean Specify the layout when listing items in git clean -i, which always shows files and directories in columns. See column.ui for details. column.status Specify whether to output untracked files in git status in columns. See column.ui for details. column.tag Specify whether to output tag listings in git tag in columns. See column.ui for details. commit.cleanup This setting overrides the default of the --cleanup option in git commit. See git-commit(1) for details. Changing the default can be useful when you always want to keep lines that begin with the comment character # in your log message, in which case you would do git config commit.cleanup whitespace (note that you will have to remove the help lines that begin with # in the commit log template yourself, if you do this). commit.gpgSign A boolean to specify whether all commits should be GPG signed. Use of this option when doing operations such as rebase can result in a large number of commits being signed. It may be convenient to use an agent to avoid typing your GPG passphrase several times. commit.status A boolean to enable/disable inclusion of status information in the commit message template when using an editor to prepare the commit message. Defaults to true. commit.template Specify the pathname of a file to use as the template for new commit messages. commit.verbose A boolean or int to specify the level of verbosity with git commit. See git-commit(1). commitGraph.generationVersion Specifies the type of generation number version to use when writing or reading the commit-graph file. If version 1 is specified, then the corrected commit dates will not be written or read. Defaults to 2. commitGraph.maxNewFilters Specifies the default value for the --max-new-filters option of git commit-graph write (c.f., git-commit-graph(1)). commitGraph.readChangedPaths If true, then git will use the changed-path Bloom filters in the commit-graph file (if it exists, and they are present). Defaults to true. See git-commit-graph(1) for more information. completion.commands This is only used by git-completion.bash to add or remove commands from the list of completed commands. Normally only porcelain commands and a few select others are completed. You can add more commands, separated by space, in this variable. Prefixing the command with - will remove it from the existing list. core.fileMode Tells Git if the executable bit of files in the working tree is to be honored. Some filesystems lose the executable bit when a file that is marked as executable is checked out, or checks out a non-executable file with executable bit on. git-clone(1) or git-init(1) probe the filesystem to see if it handles the executable bit correctly and this variable is automatically set as necessary. A repository, however, may be on a filesystem that handles the filemode correctly, and this variable is set to true when created, but later may be made accessible from another environment that loses the filemode (e.g. exporting ext4 via CIFS mount, visiting a Cygwin created repository with Git for Windows or Eclipse). In such a case it may be necessary to set this variable to false. See git- update-index(1). The default is true (when core.filemode is not specified in the config file). core.hideDotFiles (Windows-only) If true, mark newly-created directories and files whose name starts with a dot as hidden. If dotGitOnly, only the .git/ directory is hidden, but no other files starting with a dot. The default mode is dotGitOnly. core.ignoreCase Internal variable which enables various workarounds to enable Git to work better on filesystems that are not case sensitive, like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing finds "makefile" when Git expects "Makefile", Git will assume it is really the same file, and continue to remember it as "Makefile". The default is false, except git-clone(1) or git-init(1) will probe and set core.ignoreCase true if appropriate when the repository is created. Git relies on the proper configuration of this variable for your operating and file system. Modifying this value may result in unexpected behavior. core.precomposeUnicode This option is only used by Mac OS implementation of Git. When core.precomposeUnicode=true, Git reverts the unicode decomposition of filenames done by Mac OS. This is useful when sharing a repository between Mac OS and Linux or Windows. (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7). When false, file names are handled fully transparent by Git, which is backward compatible with older versions of Git. core.protectHFS If set to true, do not allow checkout of paths that would be considered equivalent to .git on an HFS+ filesystem. Defaults to true on Mac OS, and false elsewhere. core.protectNTFS If set to true, do not allow checkout of paths that would cause problems with the NTFS filesystem, e.g. conflict with 8.3 "short" names. Defaults to true on Windows, and false elsewhere. core.fsmonitor If set to true, enable the built-in file system monitor daemon for this working directory (git-fsmonitor--daemon(1)). Like hook-based file system monitors, the built-in file system monitor can speed up Git commands that need to refresh the Git index (e.g. git status) in a working directory with many files. The built-in monitor eliminates the need to install and maintain an external third-party tool. The built-in file system monitor is currently available only on a limited set of supported platforms. Currently, this includes Windows and MacOS. Otherwise, this variable contains the pathname of the "fsmonitor" hook command. This hook command is used to identify all files that may have changed since the requested date/time. This information is used to speed up git by avoiding unnecessary scanning of files that have not changed. See the "fsmonitor-watchman" section of githooks(5). Note that if you concurrently use multiple versions of Git, such as one version on the command line and another version in an IDE tool, that the definition of core.fsmonitor was extended to allow boolean values in addition to hook pathnames. Git versions 2.35.1 and prior will not understand the boolean values and will consider the "true" or "false" values as hook pathnames to be invoked. Git versions 2.26 thru 2.35.1 default to hook protocol V2 and will fall back to no fsmonitor (full scan). Git versions prior to 2.26 default to hook protocol V1 and will silently assume there were no changes to report (no scan), so status commands may report incomplete results. For this reason, it is best to upgrade all of your Git versions before using the built-in file system monitor. core.fsmonitorHookVersion Sets the protocol version to be used when invoking the "fsmonitor" hook. There are currently versions 1 and 2. When this is not set, version 2 will be tried first and if it fails then version 1 will be tried. Version 1 uses a timestamp as input to determine which files have changes since that time but some monitors like Watchman have race conditions when used with a timestamp. Version 2 uses an opaque string so that the monitor can return something that can be used to determine what files have changed without race conditions. core.trustctime If false, the ctime differences between the index and the working tree are ignored; useful when the inode change time is regularly modified by something outside Git (file system crawlers and some backup systems). See git-update-index(1). True by default. core.splitIndex If true, the split-index feature of the index will be used. See git-update-index(1). False by default. core.untrackedCache Determines what to do about the untracked cache feature of the index. It will be kept, if this variable is unset or set to keep. It will automatically be added if set to true. And it will automatically be removed, if set to false. Before setting it to true, you should check that mtime is working properly on your system. See git-update-index(1). keep by default, unless feature.manyFiles is enabled which sets this setting to true by default. core.checkStat When missing or is set to default, many fields in the stat structure are checked to detect if a file has been modified since Git looked at it. When this configuration variable is set to minimal, sub-second part of mtime and ctime, the uid and gid of the owner of the file, the inode number (and the device number, if Git was compiled to use it), are excluded from the check among these fields, leaving only the whole-second part of mtime (and ctime, if core.trustCtime is set) and the filesize to be checked. There are implementations of Git that do not leave usable values in some fields (e.g. JGit); by excluding these fields from the comparison, the minimal mode may help interoperability when the same repository is used by these other systems at the same time. core.quotePath Commands that output paths (e.g. ls-files, diff), will quote "unusual" characters in the pathname by enclosing the pathname in double-quotes and escaping those characters with backslashes in the same way C escapes control characters (e.g. \t for TAB, \n for LF, \\ for backslash) or bytes with values larger than 0x80 (e.g. octal \302\265 for "micro" in UTF-8). If this variable is set to false, bytes higher than 0x80 are not considered "unusual" any more. Double-quotes, backslash and control characters are always escaped regardless of the setting of this variable. A simple space character is not considered "unusual". Many commands can output pathnames completely verbatim using the -z option. The default value is true. core.eol Sets the line ending type to use in the working directory for files that are marked as text (either by having the text attribute set, or by having text=auto and Git auto-detecting the contents as text). Alternatives are lf, crlf and native, which uses the platform's native line ending. The default value is native. See gitattributes(5) for more information on end-of-line conversion. Note that this value is ignored if core.autocrlf is set to true or input. core.safecrlf If true, makes Git check if converting CRLF is reversible when end-of-line conversion is active. Git will verify if a command modifies a file in the work tree either directly or indirectly. For example, committing a file followed by checking out the same file should yield the original file in the work tree. If this is not the case for the current setting of core.autocrlf, Git will reject the file. The variable can be set to "warn", in which case Git will only warn about an irreversible conversion but continue the operation. CRLF conversion bears a slight chance of corrupting data. When it is enabled, Git will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by Git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data. If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell Git that this file is binary and Git will handle the file appropriately. Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data. Note, this safety check does not mean that a checkout will generate a file identical to the original file for a different setting of core.eol and core.autocrlf, but only for the current one. For example, a text file with LF would be accepted with core.eol=lf and could later be checked out with core.eol=crlf, in which case the resulting file would contain CRLF, although the original file contained LF. However, in both work trees the line endings would be consistent, that is either all LF or all CRLF, but never mixed. A file with mixed line endings would be reported by the core.safecrlf mechanism. core.autocrlf Setting this variable to "true" is the same as setting the text attribute to "auto" on all files and core.eol to "crlf". Set to true if you want to have CRLF line endings in your working directory and the repository has LF line endings. This variable can be set to input, in which case no output conversion is performed. core.checkRoundtripEncoding A comma and/or whitespace separated list of encodings that Git performs UTF-8 round trip checks on if they are used in an working-tree-encoding attribute (see gitattributes(5)). The default value is SHIFT-JIS. core.symlinks If false, symbolic links are checked out as small plain files that contain the link text. git-update-index(1) and git-add(1) will not change the recorded type to regular file. Useful on filesystems like FAT that do not support symbolic links. The default is true, except git-clone(1) or git-init(1) will probe and set core.symlinks false if appropriate when the repository is created. core.gitProxy A "proxy command" to execute (as command host port) instead of establishing direct connection to the remote server when using the Git protocol for fetching. If the variable value is in the "COMMAND for DOMAIN" format, the command is applied only on hostnames ending with the specified domain string. This variable may be set multiple times and is matched in the given order; the first match wins. Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies universally, without the special "for" handling). The special string none can be used as the proxy command to specify that no proxy be used for a given domain pattern. This is useful for excluding servers inside a firewall from proxy use, while defaulting to a common proxy for external domains. core.sshCommand If this variable is set, git fetch and git push will use the specified command instead of ssh when they need to connect to a remote system. The command is in the same form as the GIT_SSH_COMMAND environment variable and is overridden when the environment variable is set. core.ignoreStat If true, Git will avoid using lstat() calls to detect if files have changed by setting the "assume-unchanged" bit for those tracked files which it has updated identically in both the index and working tree. When files are modified outside of Git, the user will need to stage the modified files explicitly (e.g. see Examples section in git- update-index(1)). Git will not normally detect changes to those files. This is useful on systems where lstat() calls are very slow, such as CIFS/Microsoft Windows. False by default. core.preferSymlinkRefs Instead of the default "symref" format for HEAD and other symbolic reference files, use symbolic links. This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link. core.alternateRefsCommand When advertising tips of available history from an alternate, use the shell to execute the specified command instead of git-for-each- ref(1). The first argument is the absolute path of the alternate. Output must contain one hex object id per line (i.e., the same as produced by git for-each-ref --format='%(objectname)'). Note that you cannot generally put git for-each-ref directly into the config value, as it does not take a repository path as an argument (but you can wrap the command above in a shell script). core.alternateRefsPrefixes When listing references from an alternate, list only references that begin with the given prefix. Prefixes match as if they were given as arguments to git-for-each-ref(1). To list multiple prefixes, separate them with whitespace. If core.alternateRefsCommand is set, setting core.alternateRefsPrefixes has no effect. core.bare If true this repository is assumed to be bare and has no working directory associated with it. If this is the case a number of commands that require a working directory will be disabled, such as git-add(1) or git-merge(1). This setting is automatically guessed by git-clone(1) or git- init(1) when the repository was created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true). core.worktree Set the path to the root of the working tree. If GIT_COMMON_DIR environment variable is set, core.worktree is ignored and not used for determining the root of working tree. This can be overridden by the GIT_WORK_TREE environment variable and the --work-tree command-line option. The value can be an absolute path or relative to the path to the .git directory, which is either specified by --git-dir or GIT_DIR, or automatically discovered. If --git-dir or GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and core.worktree is specified, the current working directory is regarded as the top level of your working tree. Note that this variable is honored even when set in a configuration file in a ".git" subdirectory of a directory and its value differs from the latter directory (e.g. "/path/to/.git/config" has core.worktree set to "/different/path"), which is most likely a misconfiguration. Running Git commands in the "/path/to" directory will still use "/different/path" as the root of the work tree and can cause confusion unless you know what you are doing (e.g. you are creating a read-only snapshot of the same index to a location different from the repository's usual working tree). core.logAllRefUpdates Enable the reflog. Updates to a ref is logged to the file "$GIT_DIR/logs/", by appending the new and old SHA-1, the date/time and the reason of the update, but only when the file exists. If this configuration variable is set to true, missing "$GIT_DIR/logs/" file is automatically created for branch heads (i.e. under refs/heads/), remote refs (i.e. under refs/remotes/), note refs (i.e. under refs/notes/), and the symbolic ref HEAD. If it is set to always, then a missing reflog is automatically created for any ref under refs/. This information can be used to determine what commit was the tip of a branch "2 days ago". This value is true by default in a repository that has a working directory associated with it, and false by default in a bare repository. core.repositoryFormatVersion Internal variable identifying the repository format and layout version. core.sharedRepository When group (or true), the repository is made shareable between several users in a group (making sure all the files and objects are group-writable). When all (or world or everybody), the repository will be readable by all users, additionally to being group-shareable. When umask (or false), Git will use permissions reported by umask(2). When 0xxx, where 0xxx is an octal number, files in the repository will have this mode value. 0xxx will override user's umask value (whereas the other options will only override requested parts of the user's umask value). Examples: 0660 will make the repo read/write-able for the owner and group, but inaccessible to others (equivalent to group unless umask is e.g. 0022). 0640 is a repository that is group-readable but not group-writable. See git-init(1). False by default. core.warnAmbiguousRefs If true, Git will warn you if the ref name you passed it is ambiguous and might match multiple refs in the repository. True by default. core.compression An integer -1..9, indicating a default compression level. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If set, this provides a default to other compression variables, such as core.looseCompression and pack.compression. core.looseCompression An integer -1..9, indicating the compression level for objects that are not in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to 1 (best speed). core.packedGitWindowSize Number of bytes of a pack file to map into memory in a single mapping operation. Larger window sizes may allow your system to process a smaller number of large pack files more quickly. Smaller window sizes will negatively affect performance due to increased calls to the operating system's memory manager, but may improve performance when accessing a large number of large pack files. Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should be reasonable for all users/operating systems. You probably do not need to adjust this value. Common unit suffixes of k, m, or g are supported. core.packedGitLimit Maximum number of bytes to map simultaneously into memory from pack files. If Git needs to access more than this many bytes at once to complete an operation it will unmap existing regions to reclaim virtual address space within the process. Default is 256 MiB on 32 bit platforms and 32 TiB (effectively unlimited) on 64 bit platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value. Common unit suffixes of k, m, or g are supported. core.deltaBaseCacheLimit Maximum number of bytes per thread to reserve for caching base objects that may be referenced by multiple deltified objects. By storing the entire decompressed base objects in a cache Git is able to avoid unpacking and decompressing frequently used base objects multiple times. Default is 96 MiB on all platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value. Common unit suffixes of k, m, or g are supported. core.bigFileThreshold The size of files considered "big", which as discussed below changes the behavior of numerous git commands, as well as how such files are stored within the repository. The default is 512 MiB. Common unit suffixes of k, m, or g are supported. Files above the configured limit will be: o Stored deflated in packfiles, without attempting delta compression. The default limit is primarily set with this use-case in mind. With it, most projects will have their source code and other text files delta compressed, but not larger binary media files. Storing large files without delta compression avoids excessive memory usage, at the slight expense of increased disk usage. o Will be treated as if they were labeled "binary" (see gitattributes(5)). e.g. git-log(1) and git-diff(1) will not compute diffs for files above this limit. o Will generally be streamed when written, which avoids excessive memory usage, at the cost of some fixed overhead. Commands that make use of this include git-archive(1), git-fast-import(1), git-index-pack(1), git-unpack-objects(1) and git-fsck(1). core.excludesFile Specifies the pathname to the file that contains patterns to describe paths that are not meant to be tracked, in addition to .gitignore (per-directory) and .git/info/exclude. Defaults to $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore is used instead. See gitignore(5). core.askPass Some commands (e.g. svn and http interfaces) that interactively ask for a password can be told to use an external program given via the value of this variable. Can be overridden by the GIT_ASKPASS environment variable. If not set, fall back to the value of the SSH_ASKPASS environment variable or, failing that, a simple password prompt. The external program shall be given a suitable prompt as command-line argument and write the password on its STDOUT. core.attributesFile In addition to .gitattributes (per-directory) and .git/info/attributes, Git looks into this file for attributes (see gitattributes(5)). Path expansions are made the same way as for core.excludesFile. Its default value is $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/attributes is used instead. core.hooksPath By default Git will look for your hooks in the $GIT_DIR/hooks directory. Set this to different path, e.g. /etc/git/hooks, and Git will try to find your hooks in that directory, e.g. /etc/git/hooks/pre-receive instead of in $GIT_DIR/hooks/pre-receive. The path can be either absolute or relative. A relative path is taken as relative to the directory where the hooks are run (see the "DESCRIPTION" section of githooks(5)). This configuration variable is useful in cases where you'd like to centrally configure your Git hooks instead of configuring them on a per-repository basis, or as a more flexible and centralized alternative to having an init.templateDir where you've changed default hooks. core.editor Commands such as commit and tag that let you edit messages by launching an editor use the value of this variable when it is set, and the environment variable GIT_EDITOR is not set. See git-var(1). core.commentChar, core.commentString Commands such as commit and tag that let you edit messages consider a line that begins with this character commented, and removes them after the editor returns (default #). If set to "auto", git-commit would select a character that is not the beginning character of any line in existing commit messages. Note that these two variables are aliases of each other, and in modern versions of Git you are free to use a string (e.g., // or ) with commentChar. Versions of Git prior to v2.45.0 will ignore commentString but will reject a value of commentChar that consists of more than a single ASCII byte. If you plan to use your config with older and newer versions of Git, you may want to specify both: [core] # single character for older versions commentChar = "#" # string for newer versions (which will override commentChar # because it comes later in the file) commentString = "//" core.filesRefLockTimeout The length of time, in milliseconds, to retry when trying to lock an individual reference. Value 0 means not to retry at all; -1 means to try indefinitely. Default is 100 (i.e., retry for 100ms). core.packedRefsTimeout The length of time, in milliseconds, to retry when trying to lock the packed-refs file. Value 0 means not to retry at all; -1 means to try indefinitely. Default is 1000 (i.e., retry for 1 second). core.pager Text viewer for use by Git commands (e.g., less). The value is meant to be interpreted by the shell. The order of preference is the $GIT_PAGER environment variable, then core.pager configuration, then $PAGER, and then the default chosen at compile time (usually less). When the LESS environment variable is unset, Git sets it to FRX (if LESS environment variable is set, Git does not change it at all). If you want to selectively override Git's default setting for LESS, you can set core.pager to e.g. less -S. This will be passed to the shell by Git, which will translate the final command to LESS=FRX less -S. The environment does not set the S option but the command line does, instructing less to truncate long lines. Similarly, setting core.pager to less -+F will deactivate the F option specified by the environment from the command-line, deactivating the "quit if one screen" behavior of less. One can specifically activate some flags for particular commands: for example, setting pager.blame to less -S enables line truncation only for git blame. Likewise, when the LV environment variable is unset, Git sets it to -c. You can override this setting by exporting LV with another value or setting core.pager to lv +c. core.whitespace A comma separated list of common whitespace problems to notice. git diff will use color.diff.whitespace to highlight them, and git apply --whitespace=error will consider them as errors. You can prefix - to disable any of them (e.g. -trailing-space): o blank-at-eol treats trailing whitespaces at the end of the line as an error (enabled by default). o space-before-tab treats a space character that appears immediately before a tab character in the initial indent part of the line as an error (enabled by default). o indent-with-non-tab treats a line that is indented with space characters instead of the equivalent tabs as an error (not enabled by default). o tab-in-indent treats a tab character in the initial indent part of the line as an error (not enabled by default). o blank-at-eof treats blank lines added at the end of file as an error (enabled by default). o trailing-space is a short-hand to cover both blank-at-eol and blank-at-eof. o cr-at-eol treats a carriage-return at the end of line as part of the line terminator, i.e. with it, trailing-space does not trigger if the character before such a carriage-return is not a whitespace (not enabled by default). o tabwidth= tells how many character positions a tab occupies; this is relevant for indent-with-non-tab and when Git fixes tab-in-indent errors. The default tab width is 8. Allowed values are 1 to 63. core.fsync A comma-separated list of components of the repository that should be hardened via the core.fsyncMethod when created or modified. You can disable hardening of any component by prefixing it with a -. Items that are not hardened may be lost in the event of an unclean system shutdown. Unless you have special requirements, it is recommended that you leave this option empty or pick one of committed, added, or all. When this configuration is encountered, the set of components starts with the platform default value, disabled components are removed, and additional components are added. none resets the state so that the platform default is ignored. The empty string resets the fsync configuration to the platform default. The default on most platforms is equivalent to core.fsync=committed,-loose-object, which has good performance, but risks losing recent work in the event of an unclean system shutdown. o none clears the set of fsynced components. o loose-object hardens objects added to the repo in loose-object form. o pack hardens objects added to the repo in packfile form. o pack-metadata hardens packfile bitmaps and indexes. o commit-graph hardens the commit-graph file. o index hardens the index when it is modified. o objects is an aggregate option that is equivalent to loose-object,pack. o reference hardens references modified in the repo. o derived-metadata is an aggregate option that is equivalent to pack-metadata,commit-graph. o committed is an aggregate option that is currently equivalent to objects. This mode sacrifices some performance to ensure that work that is committed to the repository with git commit or similar commands is hardened. o added is an aggregate option that is currently equivalent to committed,index. This mode sacrifices additional performance to ensure that the results of commands like git add and similar operations are hardened. o all is an aggregate option that syncs all individual components above. core.fsyncMethod A value indicating the strategy Git will use to harden repository data using fsync and related primitives. o fsync uses the fsync() system call or platform equivalents. o writeout-only issues pagecache writeback requests, but depending on the filesystem and storage hardware, data added to the repository may not be durable in the event of a system crash. This is the default mode on macOS. o batch enables a mode that uses writeout-only flushes to stage multiple updates in the disk writeback cache and then does a single full fsync of a dummy file to trigger the disk cache flush at the end of the operation. Currently batch mode only applies to loose-object files. Other repository data is made durable as if fsync was specified. This mode is expected to be as safe as fsync on macOS for repos stored on HFS+ or APFS filesystems and on Windows for repos stored on NTFS or ReFS filesystems. core.fsyncObjectFiles This boolean will enable fsync() when writing object files. This setting is deprecated. Use core.fsync instead. This setting affects data added to the Git repository in loose-object form. When set to true, Git will issue an fsync or similar system call to flush caches so that loose-objects remain consistent in the face of a unclean system shutdown. core.preloadIndex Enable parallel index preload for operations like git diff This can speed up operations like git diff and git status especially on filesystems like NFS that have weak caching semantics and thus relatively high IO latencies. When enabled, Git will do the index comparison to the filesystem data in parallel, allowing overlapping IO's. Defaults to true. core.unsetenvvars Windows-only: comma-separated list of environment variables' names that need to be unset before spawning any other process. Defaults to PERL5LIB to account for the fact that Git for Windows insists on using its own Perl interpreter. core.restrictinheritedhandles Windows-only: override whether spawned processes inherit only standard file handles (stdin, stdout and stderr) or all handles. Can be auto, true or false. Defaults to auto, which means true on Windows 7 and later, and false on older Windows versions. core.createObject You can set this to link, in which case a hardlink followed by a delete of the source are used to make sure that object creation will not overwrite existing objects. On some file system/operating system combinations, this is unreliable. Set this config setting to rename there; however, this will remove the check that makes sure that existing object files will not get overwritten. core.notesRef When showing commit messages, also show notes which are stored in the given ref. The ref must be fully qualified. If the given ref does not exist, it is not an error but means that no notes should be printed. This setting defaults to "refs/notes/commits", and it can be overridden by the GIT_NOTES_REF environment variable. See git- notes(1). core.commitGraph If true, then git will read the commit-graph file (if it exists) to parse the graph structure of commits. Defaults to true. See git- commit-graph(1) for more information. core.useReplaceRefs If set to false, behave as if the --no-replace-objects option was given on the command line. See git(1) and git-replace(1) for more information. core.multiPackIndex Use the multi-pack-index file to track multiple packfiles using a single index. See git-multi-pack-index(1) for more information. Defaults to true. core.sparseCheckout Enable "sparse checkout" feature. See git-sparse-checkout(1) for more information. core.sparseCheckoutCone Enables the "cone mode" of the sparse checkout feature. When the sparse-checkout file contains a limited set of patterns, this mode provides significant performance advantages. The "non-cone mode" can be requested to allow specifying more flexible patterns by setting this variable to false. See git-sparse-checkout(1) for more information. core.abbrev Set the length object names are abbreviated to. If unspecified or set to "auto", an appropriate value is computed based on the approximate number of packed objects in your repository, which hopefully is enough for abbreviated object names to stay unique for some time. If set to "no", no abbreviation is made and the object names are shown in their full length. The minimum length is 4. core.maxTreeDepth The maximum depth Git is willing to recurse while traversing a tree (e.g., "a/b/cde/f" has a depth of 4). This is a fail-safe to allow Git to abort cleanly, and should not generally need to be adjusted. The default is 4096. credential.helper Specify an external helper to be called when a username or password credential is needed; the helper may consult external storage to avoid prompting the user for the credentials. This is normally the name of a credential helper with possible arguments, but may also be an absolute path with arguments or, if preceded by !, shell commands. Note that multiple helpers may be defined. See gitcredentials(7) for details and examples. credential.useHttpPath When acquiring credentials, consider the "path" component of an http or https URL to be important. Defaults to false. See gitcredentials(7) for more information. credential.username If no username is set for a network authentication, use this username by default. See credential..* below, and gitcredentials(7). credential..* Any of the credential.* options above can be applied selectively to some credentials. For example, "credential.https://example.com.username" would set the default username only for https connections to example.com. See gitcredentials(7) for details on how URLs are matched. credentialCache.ignoreSIGHUP Tell git-credential-cache--daemon to ignore SIGHUP, instead of quitting. credentialStore.lockTimeoutMS The length of time, in milliseconds, for git-credential-store to retry when trying to lock the credentials file. A value of 0 means not to retry at all; -1 means to try indefinitely. Default is 1000 (i.e., retry for 1s). diff.autoRefreshIndex When using git diff to compare with work tree files, do not consider stat-only changes as changed. Instead, silently run git update-index --refresh to update the cached stat information for paths whose contents in the work tree match the contents in the index. This option defaults to true. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files. diff.dirstat A comma separated list of --dirstat parameters specifying the default behavior of the --dirstat option to git-diff(1) and friends. The defaults can be overridden on the command line (using --dirstat=). The fallback defaults (when not changed by diff.dirstat) are changes,noncumulative,3. The following parameters are available: changes Compute the dirstat numbers by counting the lines that have been removed from the source, or added to the destination. This ignores the amount of pure code movements within a file. In other words, rearranging lines in a file is not counted as much as other changes. This is the default behavior when no parameter is given. lines Compute the dirstat numbers by doing the regular line-based diff analysis, and summing the removed/added line counts. (For binary files, count 64-byte chunks instead, since binary files have no natural concept of lines). This is a more expensive --dirstat behavior than the changes behavior, but it does count rearranged lines within a file as much as other changes. The resulting output is consistent with what you get from the other --*stat options. files Compute the dirstat numbers by counting the number of files changed. Each changed file counts equally in the dirstat analysis. This is the computationally cheapest --dirstat behavior, since it does not have to look at the file contents at all. cumulative Count changes in a child directory for the parent directory as well. Note that when using cumulative, the sum of the percentages reported may exceed 100%. The default (non-cumulative) behavior can be specified with the noncumulative parameter. An integer parameter specifies a cut-off percent (3% by default). Directories contributing less than this percentage of the changes are not shown in the output. Example: The following will count changed files, while ignoring directories with less than 10% of the total amount of changed files, and accumulating child directory counts in the parent directories: files,10,cumulative. diff.statNameWidth Limit the width of the filename part in --stat output. If set, applies to all commands generating --stat output except format-patch. diff.statGraphWidth Limit the width of the graph part in --stat output. If set, applies to all commands generating --stat output except format-patch. diff.context Generate diffs with lines of context instead of the default of 3. This value is overridden by the -U option. diff.interHunkContext Show the context between diff hunks, up to the specified number of lines, thereby fusing the hunks that are close to each other. This value serves as the default for the --inter-hunk-context command line option. diff.external If this config variable is set, diff generation is not performed using the internal diff machinery, but using the given command. Can be overridden with the `GIT_EXTERNAL_DIFF' environment variable. The command is called with parameters as described under "git Diffs" in git(1). Note: if you want to use an external diff program only on a subset of your files, you might want to use gitattributes(5) instead. diff.ignoreSubmodules Sets the default value of --ignore-submodules. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files. git checkout and git switch also honor this setting when reporting uncommitted changes. Setting it to all disables the submodule summary normally shown by git commit and git status when status.submoduleSummary is set unless it is overridden by using the --ignore-submodules command-line option. The git submodule commands are not affected by this setting. By default this is set to untracked so that any untracked submodules are ignored. diff.mnemonicPrefix If set, git diff uses a prefix pair that is different from the standard "a/" and "b/" depending on what is being compared. When this configuration is in effect, reverse diff output also swaps the order of the prefixes: git diff compares the (i)ndex and the (w)ork tree; git diff HEAD compares a (c)ommit and the (w)ork tree; git diff --cached compares a (c)ommit and the (i)ndex; git diff HEAD:file1 file2 compares an (o)bject and a (w)ork tree entity; git diff --no-index a b compares two non-git things (1) and (2). diff.noPrefix If set, git diff does not show any source or destination prefix. diff.srcPrefix If set, git diff uses this source prefix. Defaults to "a/". diff.dstPrefix If set, git diff uses this destination prefix. Defaults to "b/". diff.relative If set to true, git diff does not show changes outside of the directory and show pathnames relative to the current directory. diff.orderFile File indicating how to order files within a diff. See the -O option to git-diff(1) for details. If diff.orderFile is a relative pathname, it is treated as relative to the top of the working tree. diff.renameLimit The number of files to consider in the exhaustive portion of copy/rename detection; equivalent to the git diff option -l. If not set, the default value is currently 1000. This setting has no effect if rename detection is turned off. diff.renames Whether and how Git detects renames. If set to "false", rename detection is disabled. If set to "true", basic rename detection is enabled. If set to "copies" or "copy", Git will detect copies, as well. Defaults to true. Note that this affects only git diff Porcelain like git-diff(1) and git-log(1), and not lower level commands such as git-diff-files(1). diff.suppressBlankEmpty A boolean to inhibit the standard behavior of printing a space before each empty output line. Defaults to false. diff.submodule Specify the format in which differences in submodules are shown. The "short" format just shows the names of the commits at the beginning and end of the range. The "log" format lists the commits in the range like git-submodule(1) summary does. The "diff" format shows an inline diff of the changed contents of the submodule. Defaults to "short". diff.wordRegex A POSIX Extended Regular Expression used to determine what is a "word" when performing word-by-word difference calculations. Character sequences that match the regular expression are "words", all other characters are ignorable whitespace. diff..command The custom diff driver command. See gitattributes(5) for details. diff..xfuncname The regular expression that the diff driver should use to recognize the hunk header. A built-in pattern may also be used. See gitattributes(5) for details. diff..binary Set this option to true to make the diff driver treat files as binary. See gitattributes(5) for details. diff..textconv The command that the diff driver should call to generate the text-converted version of a file. The result of the conversion is used to generate a human-readable diff. See gitattributes(5) for details. diff..wordRegex The regular expression that the diff driver should use to split words in a line. See gitattributes(5) for details. diff..cachetextconv Set this option to true to make the diff driver cache the text conversion outputs. See gitattributes(5) for details. araxis Use Araxis Merge (requires a graphical session) bc Use Beyond Compare (requires a graphical session) bc3 Use Beyond Compare (requires a graphical session) bc4 Use Beyond Compare (requires a graphical session) codecompare Use Code Compare (requires a graphical session) deltawalker Use DeltaWalker (requires a graphical session) diffmerge Use DiffMerge (requires a graphical session) diffuse Use Diffuse (requires a graphical session) ecmerge Use ECMerge (requires a graphical session) emerge Use Emacs' Emerge examdiff Use ExamDiff Pro (requires a graphical session) guiffy Use Guiffy's Diff Tool (requires a graphical session) gvimdiff Use gVim (requires a graphical session) kdiff3 Use KDiff3 (requires a graphical session) kompare Use Kompare (requires a graphical session) meld Use Meld (requires a graphical session) nvimdiff Use Neovim opendiff Use FileMerge (requires a graphical session) p4merge Use HelixCore P4Merge (requires a graphical session) smerge Use Sublime Merge (requires a graphical session) tkdiff Use TkDiff (requires a graphical session) vimdiff Use Vim winmerge Use WinMerge (requires a graphical session) xxdiff Use xxdiff (requires a graphical session) diff.indentHeuristic Set this option to false to disable the default heuristics that shift diff hunk boundaries to make patches easier to read. diff.algorithm Choose a diff algorithm. The variants are as follows: default, myers The basic greedy diff algorithm. Currently, this is the default. minimal Spend extra time to make sure the smallest possible diff is produced. patience Use "patience diff" algorithm when generating patches. histogram This algorithm extends the patience algorithm to "support low-occurrence common elements". diff.wsErrorHighlight Highlight whitespace errors in the context, old or new lines of the diff. Multiple values are separated by comma, none resets previous values, default reset the list to new and all is a shorthand for old,new,context. The whitespace errors are colored with color.diff.whitespace. The command line option --ws-error-highlight= overrides this setting. diff.colorMoved If set to either a valid or a true value, moved lines in a diff are colored differently, for details of valid modes see --color-moved in git-diff(1). If simply set to true the default color mode will be used. When set to false, moved lines are not colored. diff.colorMovedWS When moved lines are colored using e.g. the diff.colorMoved setting, this option controls the how spaces are treated. For details of valid modes see --color-moved-ws in git-diff(1). diff.tool Controls which diff tool is used by git-difftool(1). This variable overrides the value configured in merge.tool. The list below shows the valid built-in values. Any other value is treated as a custom diff tool and requires that a corresponding difftool..cmd variable is defined. diff.guitool Controls which diff tool is used by git-difftool(1) when the -g/--gui flag is specified. This variable overrides the value configured in merge.guitool. The list below shows the valid built-in values. Any other value is treated as a custom diff tool and requires that a corresponding difftool..cmd variable is defined. difftool..cmd Specify the command to invoke the specified diff tool. The specified command is evaluated in shell with the following variables available: LOCAL is set to the name of the temporary file containing the contents of the diff pre-image and REMOTE is set to the name of the temporary file containing the contents of the diff post-image. See the --tool= option in git-difftool(1) for more details. difftool..path Override the path for the given tool. This is useful in case your tool is not in the PATH. difftool.trustExitCode Exit difftool if the invoked diff tool returns a non-zero exit status. See the --trust-exit-code option in git-difftool(1) for more details. difftool.prompt Prompt before each invocation of the diff tool. difftool.guiDefault Set true to use the diff.guitool by default (equivalent to specifying the --gui argument), or auto to select diff.guitool or diff.tool depending on the presence of a DISPLAY environment variable value. The default is false, where the --gui argument must be provided explicitly for the diff.guitool to be used. extensions.objectFormat Specify the hash algorithm to use. The acceptable values are sha1 and sha256. If not specified, sha1 is assumed. It is an error to specify this key unless core.repositoryFormatVersion is 1. Note that this setting should only be set by git-init(1) or git- clone(1). Trying to change it after initialization will not work and will produce hard-to-diagnose issues. extensions.compatObjectFormat Specify a compatitbility hash algorithm to use. The acceptable values are sha1 and sha256. The value specified must be different from the value of extensions.objectFormat. This allows client level interoperability between git repositories whose objectFormat matches this compatObjectFormat. In particular when fully implemented the pushes and pulls from a repository in whose objectFormat matches compatObjectFormat. As well as being able to use oids encoded in compatObjectFormat in addition to oids encoded with objectFormat to locally specify objects. extensions.refStorage Specify the ref storage format to use. The acceptable values are: o files for loose files with packed-refs. This is the default. o reftable for the reftable format. This format is experimental and its internals are subject to change. It is an error to specify this key unless core.repositoryFormatVersion is 1. Note that this setting should only be set by git-init(1) or git-clone(1). Trying to change it after initialization will not work and will produce hard-to-diagnose issues. extensions.worktreeConfig If enabled, then worktrees will load config settings from the $GIT_DIR/config.worktree file in addition to the $GIT_COMMON_DIR/config file. Note that $GIT_COMMON_DIR and $GIT_DIR are the same for the main working tree, while other working trees have $GIT_DIR equal to $GIT_COMMON_DIR/worktrees//. The settings in the config.worktree file will override settings from any other config files. When enabling extensions.worktreeConfig, you must be careful to move certain values from the common config file to the main working tree's config.worktree file, if present: o core.worktree must be moved from $GIT_COMMON_DIR/config to $GIT_COMMON_DIR/config.worktree. o If core.bare is true, then it must be moved from $GIT_COMMON_DIR/config to $GIT_COMMON_DIR/config.worktree. It may also be beneficial to adjust the locations of core.sparseCheckout and core.sparseCheckoutCone depending on your desire for customizable sparse-checkout settings for each worktree. By default, the git sparse-checkout builtin enables extensions.worktreeConfig, assigns these config values on a per-worktree basis, and uses the $GIT_DIR/info/sparse-checkout file to specify the sparsity for each worktree independently. See git-sparse-checkout(1) for more details. For historical reasons, extensions.worktreeConfig is respected regardless of the core.repositoryFormatVersion setting. fastimport.unpackLimit If the number of objects imported by git-fast-import(1) is below this limit, then the objects will be unpacked into loose object files. However, if the number of imported objects equals or exceeds this limit, then the pack will be stored as a pack. Storing the pack from a fast-import can make the import operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead. feature.* The config settings that start with feature. modify the defaults of a group of other config settings. These groups are created by the Git developer community as recommended defaults and are subject to change. In particular, new config options may be added with different defaults. feature.experimental Enable config options that are new to Git, and are being considered for future defaults. Config settings included here may be added or removed with each release, including minor version updates. These settings may have unintended interactions since they are so new. Please enable this setting if you are interested in providing feedback on experimental features. The new default values are: o fetch.negotiationAlgorithm=skipping may improve fetch negotiation times by skipping more commits at a time, reducing the number of round trips. o pack.useBitmapBoundaryTraversal=true may improve bitmap traversal times by walking fewer objects. o pack.allowPackReuse=multi may improve the time it takes to create a pack by reusing objects from multiple packs instead of just one. feature.manyFiles Enable config options that optimize for repos with many files in the working directory. With many files, commands such as git status and git checkout may be slow and these new defaults improve performance: o index.skipHash=true speeds up index writes by not computing a trailing checksum. Note that this will cause Git versions earlier than 2.13.0 to refuse to parse the index and Git versions earlier than 2.40.0 will report a corrupted index during git fsck. o index.version=4 enables path-prefix compression in the index. o core.untrackedCache=true enables the untracked cache. This setting assumes that mtime is working on your machine. fetch.recurseSubmodules This option controls whether git fetch (and the underlying fetch in git pull) will recursively fetch into populated submodules. This option can be set either to a boolean value or to on-demand. Setting it to a boolean changes the behavior of fetch and pull to recurse unconditionally into submodules when set to true or to not recurse at all when set to false. When set to on-demand, fetch and pull will only recurse into a populated submodule when its superproject retrieves a commit that updates the submodule's reference. Defaults to on-demand, or to the value of submodule.recurse if set. fetch.fsckObjects If it is set to true, git-fetch-pack will check all fetched objects. See transfer.fsckObjects for what's checked. Defaults to false. If not set, the value of transfer.fsckObjects is used instead. fetch.fsck. Acts like fsck., but is used by git-fetch-pack(1) instead of git-fsck(1). See the fsck. documentation for details. fetch.fsck.skipList Acts like fsck.skipList, but is used by git-fetch-pack(1) instead of git-fsck(1). See the fsck.skipList documentation for details. fetch.unpackLimit If the number of objects fetched over the Git native transfer is below this limit, then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead. fetch.prune If true, fetch will automatically behave as if the --prune option was given on the command line. See also remote..prune and the PRUNING section of git-fetch(1). fetch.pruneTags If true, fetch will automatically behave as if the refs/tags/*:refs/tags/* refspec was provided when pruning, if not set already. This allows for setting both this option and fetch.prune to maintain a 1=1 mapping to upstream refs. See also remote..pruneTags and the PRUNING section of git-fetch(1). fetch.all If true, fetch will attempt to update all available remotes. This behavior can be overridden by passing --no-all or by explicitly specifying one or more remote(s) to fetch from. Defaults to false. fetch.output Control how ref update status is printed. Valid values are full and compact. Default value is full. See the OUTPUT section in git- fetch(1) for details. fetch.negotiationAlgorithm Control how information about the commits in the local repository is sent when negotiating the contents of the packfile to be sent by the server. Set to "consecutive" to use an algorithm that walks over consecutive commits checking each one. Set to "skipping" to use an algorithm that skips commits in an effort to converge faster, but may result in a larger-than-necessary packfile; or set to "noop" to not send any information at all, which will almost certainly result in a larger-than-necessary packfile, but will skip the negotiation step. Set to "default" to override settings made previously and use the default behaviour. The default is normally "consecutive", but if feature.experimental is true, then the default is "skipping". Unknown values will cause git fetch to error out. See also the --negotiate-only and --negotiation-tip options to git- fetch(1). fetch.showForcedUpdates Set to false to enable --no-show-forced-updates in git-fetch(1) and git-pull(1) commands. Defaults to true. fetch.parallel Specifies the maximal number of fetch operations to be run in parallel at a time (submodules, or remotes when the --multiple option of git-fetch(1) is in effect). A value of 0 will give some reasonable default. If unset, it defaults to 1. For submodules, this setting can be overridden using the submodule.fetchJobs config setting. fetch.writeCommitGraph Set to true to write a commit-graph after every git fetch command that downloads a pack-file from a remote. Using the --split option, most executions will create a very small commit-graph file on top of the existing commit-graph file(s). Occasionally, these files will merge and the write may take longer. Having an updated commit-graph file helps performance of many Git commands, including git merge-base, git push -f, and git log --graph. Defaults to false. fetch.bundleURI This value stores a URI for downloading Git object data from a bundle URI before performing an incremental fetch from the origin Git server. This is similar to how the --bundle-uri option behaves in git-clone(1). git clone --bundle-uri will set the fetch.bundleURI value if the supplied bundle URI contains a bundle list that is organized for incremental fetches. If you modify this value and your repository has a fetch.bundleCreationToken value, then remove that fetch.bundleCreationToken value before fetching from the new bundle URI. fetch.bundleCreationToken When using fetch.bundleURI to fetch incrementally from a bundle list that uses the "creationToken" heuristic, this config value stores the maximum creationToken value of the downloaded bundles. This value is used to prevent downloading bundles in the future if the advertised creationToken is not strictly larger than this value. The creation token values are chosen by the provider serving the specific bundle URI. If you modify the URI at fetch.bundleURI, then be sure to remove the value for the fetch.bundleCreationToken value before fetching. filter..clean The command which is used to convert the content of a worktree file to a blob upon checkin. See gitattributes(5) for details. filter..smudge The command which is used to convert the content of a blob object to a worktree file upon checkout. See gitattributes(5) for details. format.attach Enable multipart/mixed attachments as the default for format-patch. The value can also be a double quoted string which will enable attachments as the default and set the value as the boundary. See the --attach option in git-format-patch(1). To countermand an earlier value, set it to an empty string. format.from Provides the default value for the --from option to format-patch. Accepts a boolean value, or a name and email address. If false, format-patch defaults to --no-from, using commit authors directly in the "From:" field of patch mails. If true, format-patch defaults to --from, using your committer identity in the "From:" field of patch mails and including a "From:" field in the body of the patch mail if different. If set to a non-boolean value, format-patch uses that value instead of your committer identity. Defaults to false. format.forceInBodyFrom Provides the default value for the --[no-]force-in-body-from option to format-patch. Defaults to false. format.numbered A boolean which can enable or disable sequence numbers in patch subjects. It defaults to "auto" which enables it only if there is more than one patch. It can be enabled or disabled for all messages by setting it to "true" or "false". See --numbered option in git- format-patch(1). format.headers Additional email headers to include in a patch to be submitted by mail. See git-format-patch(1). format.to, format.cc Additional recipients to include in a patch to be submitted by mail. See the --to and --cc options in git-format-patch(1). format.subjectPrefix The default for format-patch is to output files with the [PATCH] subject prefix. Use this variable to change that prefix. format.coverFromDescription The default mode for format-patch to determine which parts of the cover letter will be populated using the branch's description. See the --cover-from-description option in git-format-patch(1). format.signature The default for format-patch is to output a signature containing the Git version number. Use this variable to change that default. Set this variable to the empty string ("") to suppress signature generation. format.signatureFile Works just like format.signature except the contents of the file specified by this variable will be used as the signature. format.suffix The default for format-patch is to output files with the suffix .patch. Use this variable to change that suffix (make sure to include the dot if you want it). format.encodeEmailHeaders Encode email headers that have non-ASCII characters with "Q-encoding" (described in RFC 2047) for email transmission. Defaults to true. format.pretty The default pretty format for log/show/whatchanged command. See git-log(1), git-show(1), git-whatchanged(1). format.thread The default threading style for git format-patch. Can be a boolean value, or shallow or deep. shallow threading makes every mail a reply to the head of the series, where the head is chosen from the cover letter, the --in-reply-to, and the first patch mail, in this order. deep threading makes every mail a reply to the previous one. A true boolean value is the same as shallow, and a false value disables threading. format.signOff A boolean value which lets you enable the -s/--signoff option of format-patch by default. Note: Adding the Signed-off-by trailer to a patch should be a conscious act and means that you certify you have the rights to submit this work under the same open source license. Please see the SubmittingPatches document for further discussion. format.coverLetter A boolean that controls whether to generate a cover-letter when format-patch is invoked, but in addition can be set to "auto", to generate a cover-letter only when there's more than one patch. Default is false. format.outputDirectory Set a custom directory to store the resulting files instead of the current working directory. All directory components will be created. format.filenameMaxLength The maximum length of the output filenames generated by the format-patch command; defaults to 64. Can be overridden by the --filename-max-length= command line option. format.useAutoBase A boolean value which lets you enable the --base=auto option of format-patch by default. Can also be set to "whenAble" to allow enabling --base=auto if a suitable base is available, but to skip adding base info otherwise without the format dying. format.notes Provides the default value for the --notes option to format-patch. Accepts a boolean value, or a ref which specifies where to get notes. If false, format-patch defaults to --no-notes. If true, format-patch defaults to --notes. If set to a non-boolean value, format-patch defaults to --notes=, where ref is the non-boolean value. Defaults to false. If one wishes to use the ref refs/notes/true, please use that literal instead. This configuration can be specified multiple times in order to allow multiple notes refs to be included. In that case, it will behave similarly to multiple --[no-]notes[=] options passed in. That is, a value of true will show the default notes, a value of will also show notes from that notes ref and a value of false will negate previous configurations and not show notes. For example, [format] notes = true notes = foo notes = false notes = bar will only show notes from refs/notes/bar. format.mboxrd A boolean value which enables the robust "mboxrd" format when --stdout is in use to escape "^>+From " lines. format.noprefix If set, do not show any source or destination prefix in patches. This is equivalent to the diff.noprefix option used by git diff (but which is not respected by format-patch). Note that by setting this, the receiver of any patches you generate will have to apply them using the -p0 option. fsck. During fsck git may find issues with legacy data which wouldn't be generated by current versions of git, and which wouldn't be sent over the wire if transfer.fsckObjects was set. This feature is intended to support working with legacy repositories containing such data. Setting fsck. will be picked up by git-fsck(1), but to accept pushes of such data set receive.fsck. instead, or to clone or fetch it set fetch.fsck.. The rest of the documentation discusses fsck.* for brevity, but the same applies for the corresponding receive.fsck.* and fetch.fsck.*. variables. Unlike variables like color.ui and core.editor, the receive.fsck. and fetch.fsck. variables will not fall back on the fsck. configuration if they aren't set. To uniformly configure the same fsck settings in different circumstances, all three of them must be set to the same values. When fsck. is set, errors can be switched to warnings and vice versa by configuring the fsck. setting where the is the fsck message ID and the value is one of error, warn or ignore. For convenience, fsck prefixes the error/warning with the message ID, e.g. "missingEmail: invalid author/committer line - missing email" means that setting fsck.missingEmail = ignore will hide that issue. In general, it is better to enumerate existing objects with problems with fsck.skipList, instead of listing the kind of breakages these problematic objects share to be ignored, as doing the latter will allow new instances of the same breakages go unnoticed. Setting an unknown fsck. value will cause fsck to die, but doing the same for receive.fsck. and fetch.fsck. will only cause git to warn. See the Fsck Messages section of git-fsck(1) for supported values of . fsck.skipList The path to a list of object names (i.e. one unabbreviated SHA-1 per line) that are known to be broken in a non-fatal way and should be ignored. On versions of Git 2.20 and later, comments (#), empty lines, and any leading and trailing whitespace are ignored. Everything but a SHA-1 per line will error out on older versions. This feature is useful when an established project should be accepted despite early commits containing errors that can be safely ignored, such as invalid committer email addresses. Note: corrupt objects cannot be skipped with this setting. Like fsck. this variable has corresponding receive.fsck.skipList and fetch.fsck.skipList variants. Unlike variables like color.ui and core.editor the receive.fsck.skipList and fetch.fsck.skipList variables will not fall back on the fsck.skipList configuration if they aren't set. To uniformly configure the same fsck settings in different circumstances, all three of them must be set to the same values. Older versions of Git (before 2.20) documented that the object names list should be sorted. This was never a requirement; the object names could appear in any order, but when reading the list we tracked whether the list was sorted for the purposes of an internal binary search implementation, which could save itself some work with an already sorted list. Unless you had a humongous list there was no reason to go out of your way to pre-sort the list. After Git version 2.20 a hash implementation is used instead, so there's now no reason to pre-sort the list. fsmonitor.allowRemote By default, the fsmonitor daemon refuses to work with network-mounted repositories. Setting fsmonitor.allowRemote to true overrides this behavior. Only respected when core.fsmonitor is set to true. fsmonitor.socketDir This Mac OS-specific option, if set, specifies the directory in which to create the Unix domain socket used for communication between the fsmonitor daemon and various Git commands. The directory must reside on a native Mac OS filesystem. Only respected when core.fsmonitor is set to true. gc.aggressiveDepth The depth parameter used in the delta compression algorithm used by git gc --aggressive. This defaults to 50, which is the default for the --depth option when --aggressive isn't in use. See the documentation for the --depth option in git-repack(1) for more details. gc.aggressiveWindow The window size parameter used in the delta compression algorithm used by git gc --aggressive. This defaults to 250, which is a much more aggressive window size than the default --window of 10. See the documentation for the --window option in git-repack(1) for more details. gc.auto When there are approximately more than this many loose objects in the repository, git gc --auto will pack them. Some Porcelain commands use this command to perform a light-weight garbage collection from time to time. The default value is 6700. Setting this to 0 disables not only automatic packing based on the number of loose objects, but also any other heuristic git gc --auto will otherwise use to determine if there's work to do, such as gc.autoPackLimit. gc.autoPackLimit When there are more than this many packs that are not marked with *.keep file in the repository, git gc --auto consolidates them into one larger pack. The default value is 50. Setting this to 0 disables it. Setting gc.auto to 0 will also disable this. See the gc.bigPackThreshold configuration variable below. When in use, it'll affect how the auto pack limit works. gc.autoDetach Make git gc --auto return immediately and run in the background if the system supports it. Default is true. gc.bigPackThreshold If non-zero, all non-cruft packs larger than this limit are kept when git gc is run. This is very similar to --keep-largest-pack except that all non-cruft packs that meet the threshold are kept, not just the largest pack. Defaults to zero. Common unit suffixes of k, m, or g are supported. Note that if the number of kept packs is more than gc.autoPackLimit, this configuration variable is ignored, all packs except the base pack will be repacked. After this the number of packs should go below gc.autoPackLimit and gc.bigPackThreshold should be respected again. If the amount of memory estimated for git repack to run smoothly is not available and gc.bigPackThreshold is not set, the largest pack will also be excluded (this is the equivalent of running git gc with --keep-largest-pack). gc.writeCommitGraph If true, then gc will rewrite the commit-graph file when git-gc(1) is run. When using git gc --auto the commit-graph will be updated if housekeeping is required. Default is true. See git-commit- graph(1) for details. gc.logExpiry If the file gc.log exists, then git gc --auto will print its content and exit with status zero instead of running unless that file is more than gc.logExpiry old. Default is "1.day". See gc.pruneExpire for more ways to specify its value. gc.packRefs Running git pack-refs in a repository renders it unclonable by Git versions prior to 1.5.1.2 over dumb transports such as HTTP. This variable determines whether git gc runs git pack-refs. This can be set to notbare to enable it within all non-bare repos or it can be set to a boolean value. The default is true. gc.cruftPacks Store unreachable objects in a cruft pack (see git-repack(1)) instead of as loose objects. The default is true. gc.maxCruftSize Limit the size of new cruft packs when repacking. When specified in addition to --max-cruft-size, the command line option takes priority. See the --max-cruft-size option of git-repack(1). gc.pruneExpire When git gc is run, it will call prune --expire 2.weeks.ago (and repack --cruft --cruft-expiration 2.weeks.ago if using cruft packs via gc.cruftPacks or --cruft). Override the grace period with this config variable. The value "now" may be used to disable this grace period and always prune unreachable objects immediately, or "never" may be used to suppress pruning. This feature helps prevent corruption when git gc runs concurrently with another process writing to the repository; see the "NOTES" section of git-gc(1). gc.worktreePruneExpire When git gc is run, it calls git worktree prune --expire 3.months.ago. This config variable can be used to set a different grace period. The value "now" may be used to disable the grace period and prune $GIT_DIR/worktrees immediately, or "never" may be used to suppress pruning. gc.reflogExpire, gc..reflogExpire git reflog expire removes reflog entries older than this time; defaults to 90 days. The value "now" expires all entries immediately, and "never" suppresses expiration altogether. With "" (e.g. "refs/stash") in the middle the setting applies only to the refs that match the . gc.reflogExpireUnreachable, gc..reflogExpireUnreachable git reflog expire removes reflog entries older than this time and are not reachable from the current tip; defaults to 30 days. The value "now" expires all entries immediately, and "never" suppresses expiration altogether. With "" (e.g. "refs/stash") in the middle, the setting applies only to the refs that match the . These types of entries are generally created as a result of using git commit --amend or git rebase and are the commits prior to the amend or rebase occurring. Since these changes are not part of the current project most users will want to expire them sooner, which is why the default is more aggressive than gc.reflogExpire. gc.recentObjectsHook When considering whether or not to remove an object (either when generating a cruft pack or storing unreachable objects as loose), use the shell to execute the specified command(s). Interpret their output as object IDs which Git will consider as "recent", regardless of their age. By treating their mtimes as "now", any objects (and their descendants) mentioned in the output will be kept regardless of their true age. Output must contain exactly one hex object ID per line, and nothing else. Objects which cannot be found in the repository are ignored. Multiple hooks are supported, but all must exit successfully, else the operation (either generating a cruft pack or unpacking unreachable objects) will be halted. gc.repackFilter When repacking, use the specified filter to move certain objects into a separate packfile. See the --filter= option of git-repack(1). gc.repackFilterTo When repacking and using a filter, see gc.repackFilter, the specified location will be used to create the packfile containing the filtered out objects. WARNING: The specified location should be accessible, using for example the Git alternates mechanism, otherwise the repo could be considered corrupt by Git as it migh not be able to access the objects in that packfile. See the --filter-to= option of git-repack(1) and the objects/info/alternates section of gitrepository-layout(5). gc.rerereResolved Records of conflicted merge you resolved earlier are kept for this many days when git rerere gc is run. You can also use more human-readable "1.month.ago", etc. The default is 60 days. See git- rerere(1). gc.rerereUnresolved Records of conflicted merge you have not resolved are kept for this many days when git rerere gc is run. You can also use more human-readable "1.month.ago", etc. The default is 15 days. See git- rerere(1). gitcvs.commitMsgAnnotation Append this string to each commit message. Set to empty string to disable this feature. Defaults to "via git-CVS emulator". gitcvs.enabled Whether the CVS server interface is enabled for this repository. See git-cvsserver(1). gitcvs.logFile Path to a log file where the CVS server interface well... logs various stuff. See git-cvsserver(1). gitcvs.usecrlfattr If true, the server will look up the end-of-line conversion attributes for files to determine the -k modes to use. If the attributes force Git to treat a file as text, the -k mode will be left blank so CVS clients will treat it as text. If they suppress text conversion, the file will be set with -kb mode, which suppresses any newline munging the client might otherwise do. If the attributes do not allow the file type to be determined, then gitcvs.allBinary is used. See gitattributes(5). gitcvs.allBinary This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If true, all unresolved files are sent to the client in mode -kb. This causes the client to treat them as binary files, which suppresses any newline munging it otherwise might do. Alternatively, if it is set to "guess", then the contents of the file are examined to decide if it is binary, similar to core.autocrlf. gitcvs.dbName Database used by git-cvsserver to cache revision information derived from the Git repository. The exact meaning depends on the used database driver, for SQLite (which is the default driver) this is a filename. Supports variable substitution (see git-cvsserver(1) for details). May not contain semicolons (;). Default: %Ggitcvs.%m.sqlite gitcvs.dbDriver Used Perl DBI driver. You can specify any available driver for this here, but it might not work. git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and reported not to work with DBD::mysql. Experimental feature. May not contain double colons (:). Default: SQLite. See git-cvsserver(1). gitcvs.dbUser, gitcvs.dbPass Database user and password. Only useful if setting gitcvs.dbDriver, since SQLite has no concept of database users and/or passwords. gitcvs.dbUser supports variable substitution (see git-cvsserver(1) for details). gitcvs.dbTableNamePrefix Database table name prefix. Prepended to the names of any database tables used, allowing a single database to be used for several repositories. Supports variable substitution (see git-cvsserver(1) for details). Any non-alphabetic characters will be replaced with underscores. All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allBinary can also be specified as gitcvs.. (where access_method is one of "ext" and "pserver") to make them apply only for the given access method. gitweb.category, gitweb.description, gitweb.owner, gitweb.url See gitweb(1) for description. gitweb.avatar, gitweb.blame, gitweb.grep, gitweb.highlight, gitweb.patches, gitweb.pickaxe, gitweb.remote_heads, gitweb.showSizes, gitweb.snapshot See gitweb.conf(5) for description. gpg.program Use this custom program instead of "gpg" found on $PATH when making or verifying a PGP signature. The program must support the same command-line interface as GPG, namely, to verify a detached signature, "gpg --verify $signature - <$file" is run, and the program is expected to signal a good signature by exiting with code 0. To generate an ASCII-armored detached signature, the standard input of "gpg -bsau $key" is fed with the contents to be signed, and the program is expected to send the result to its standard output. gpg.format Specifies which key format to use when signing with --gpg-sign. Default is "openpgp". Other possible values are "x509", "ssh". See gitformat-signature(5) for the signature format, which differs based on the selected gpg.format. gpg..program Use this to customize the program used for the signing format you chose. (see gpg.program and gpg.format) gpg.program can still be used as a legacy synonym for gpg.openpgp.program. The default value for gpg.x509.program is "gpgsm" and gpg.ssh.program is "ssh-keygen". gpg.minTrustLevel Specifies a minimum trust level for signature verification. If this option is unset, then signature verification for merge operations requires a key with at least marginal trust. Other operations that perform signature verification require a key with at least undefined trust. Setting this option overrides the required trust-level for all operations. Supported values, in increasing order of significance: o undefined o never o marginal o fully o ultimate gpg.ssh.defaultKeyCommand This command will be run when user.signingkey is not set and a ssh signature is requested. On successful exit a valid ssh public key prefixed with key:: is expected in the first line of its output. This allows for a script doing a dynamic lookup of the correct public key when it is impractical to statically configure user.signingKey. For example when keys or SSH Certificates are rotated frequently or selection of the right key depends on external factors unknown to git. gpg.ssh.allowedSignersFile A file containing ssh public keys which you are willing to trust. The file consists of one or more lines of principals followed by an ssh public key. e.g.: user1@example.com,user2@example.com ssh-rsa AAAAX1... See ssh-keygen(1) "ALLOWED SIGNERS" for details. The principal is only used to identify the key and is available when verifying a signature. SSH has no concept of trust levels like gpg does. To be able to differentiate between valid signatures and trusted signatures the trust level of a signature verification is set to fully when the public key is present in the allowedSignersFile. Otherwise the trust level is undefined and git verify-commit/tag will fail. This file can be set to a location outside of the repository and every developer maintains their own trust store. A central repository server could generate this file automatically from ssh keys with push access to verify the code against. In a corporate setting this file is probably generated at a global location from automation that already handles developer ssh keys. A repository that only allows signed commits can store the file in the repository itself using a path relative to the top-level of the working tree. This way only committers with an already valid key can add or change keys in the keyring. Since OpensSSH 8.8 this file allows specifying a key lifetime using valid-after & valid-before options. Git will mark signatures as valid if the signing key was valid at the time of the signature's creation. This allows users to change a signing key without invalidating all previously made signatures. Using a SSH CA key with the cert-authority option (see ssh-keygen(1) "CERTIFICATES") is also valid. gpg.ssh.revocationFile Either a SSH KRL or a list of revoked public keys (without the principal prefix). See ssh-keygen(1) for details. If a public key is found in this file then it will always be treated as having trust level "never" and signatures will show as invalid. grep.lineNumber If set to true, enable -n option by default. grep.column If set to true, enable the --column option by default. grep.patternType Set the default matching behavior. Using a value of basic, extended, fixed, or perl will enable the --basic-regexp, --extended-regexp, --fixed-strings, or --perl-regexp option accordingly, while the value default will use the grep.extendedRegexp option to choose between basic and extended. grep.extendedRegexp If set to true, enable --extended-regexp option by default. This option is ignored when the grep.patternType option is set to a value other than default. grep.threads Number of grep worker threads to use. If unset (or set to 0), Git will use as many threads as the number of logical cores available. grep.fullName If set to true, enable --full-name option by default. grep.fallbackToNoIndex If set to true, fall back to git grep --no-index if git grep is executed outside of a git repository. Defaults to false. gui.commitMsgWidth Defines how wide the commit message window is in the git-gui(1). "75" is the default. gui.diffContext Specifies how many context lines should be used in calls to diff made by the git-gui(1). The default is "5". gui.displayUntracked Determines if git-gui(1) shows untracked files in the file list. The default is "true". gui.encoding Specifies the default character encoding to use for displaying of file contents in git-gui(1) and gitk(1). It can be overridden by setting the encoding attribute for relevant files (see gitattributes(5)). If this option is not set, the tools default to the locale encoding. gui.matchTrackingBranch Determines if new branches created with git-gui(1) should default to tracking remote branches with matching names or not. Default: "false". gui.newBranchTemplate Is used as a suggested name when creating new branches using the git-gui(1). gui.pruneDuringFetch "true" if git-gui(1) should prune remote-tracking branches when performing a fetch. The default value is "false". gui.trustmtime Determines if git-gui(1) should trust the file modification timestamp or not. By default the timestamps are not trusted. gui.spellingDictionary Specifies the dictionary used for spell checking commit messages in the git-gui(1). When set to "none" spell checking is turned off. gui.fastCopyBlame If true, git gui blame uses -C instead of -C -C for original location detection. It makes blame significantly faster on huge repositories at the expense of less thorough copy detection. gui.copyBlameThreshold Specifies the threshold to use in git gui blame original location detection, measured in alphanumeric characters. See the git- blame(1) manual for more information on copy detection. gui.blamehistoryctx Specifies the radius of history context in days to show in gitk(1) for the selected commit, when the Show History Context menu item is invoked from git gui blame. If this variable is set to zero, the whole history is shown. guitool..cmd Specifies the shell command line to execute when the corresponding item of the git-gui(1) Tools menu is invoked. This option is mandatory for every tool. The command is executed from the root of the working directory, and in the environment it receives the name of the tool as GIT_GUITOOL, the name of the currently selected file as FILENAME, and the name of the current branch as CUR_BRANCH (if the head is detached, CUR_BRANCH is empty). guitool..needsFile Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not empty. guitool..noConsole Run the command silently, without creating a window to display its output. guitool..noRescan Don't rescan the working directory for changes after the tool finishes execution. guitool..confirm Show a confirmation dialog before actually running the tool. guitool..argPrompt Request a string argument from the user, and pass it to the tool through the ARGS environment variable. Since requesting an argument implies confirmation, the confirm option has no effect if this is enabled. If the option is set to true, yes, or 1, the dialog uses a built-in generic prompt; otherwise the exact value of the variable is used. guitool..revPrompt Request a single valid revision from the user, and set the REVISION environment variable. In other aspects this option is similar to argPrompt, and can be used together with it. guitool..revUnmerged Show only unmerged branches in the revPrompt subdialog. This is useful for tools similar to merge or rebase, but not for things like checkout or reset. guitool..title Specifies the title to use for the prompt dialog. The default is the tool name. guitool..prompt Specifies the general prompt string to display at the top of the dialog, before subsections for argPrompt and revPrompt. The default value includes the actual command. help.browser Specify the browser that will be used to display help in the web format. See git-help(1). help.format Override the default help format used by git-help(1). Values man, info, web and html are supported. man is the default. web and html are the same. help.autoCorrect If git detects typos and can identify exactly one valid command similar to the error, git will try to suggest the correct command or even run the suggestion automatically. Possible config values are: o 0 (default): show the suggested command. o positive number: run the suggested command after specified deciseconds (0.1 sec). o "immediate": run the suggested command immediately. o "prompt": show the suggestion and prompt for confirmation to run the command. o "never": don't run or show any suggested command. help.htmlPath Specify the path where the HTML documentation resides. File system paths and URLs are supported. HTML pages will be prefixed with this path when help is displayed in the web format. This defaults to the documentation path of your Git installation. http.proxy Override the HTTP proxy, normally configured using the http_proxy, https_proxy, and all_proxy environment variables (see curl(1)). In addition to the syntax understood by curl, it is possible to specify a proxy string with a user name but no password, in which case git will attempt to acquire one in the same way it does for other credentials. See gitcredentials(7) for more information. The syntax thus is [protocol://][user[:password]@]proxyhost[:port]. This can be overridden on a per-remote basis; see remote..proxy http.proxyAuthMethod Set the method with which to authenticate against the HTTP proxy. This only takes effect if the configured proxy string contains a user name part (i.e. is of the form user@host or user@host:port). This can be overridden on a per-remote basis; see remote..proxyAuthMethod. Both can be overridden by the GIT_HTTP_PROXY_AUTHMETHOD environment variable. Possible values are: o anyauth - Automatically pick a suitable authentication method. It is assumed that the proxy answers an unauthenticated request with a 407 status code and one or more Proxy-authenticate headers with supported authentication methods. This is the default. o basic - HTTP Basic authentication o digest - HTTP Digest authentication; this prevents the password from being transmitted to the proxy in clear text o negotiate - GSS-Negotiate authentication (compare the --negotiate option of curl(1)) o ntlm - NTLM authentication (compare the --ntlm option of curl(1)) http.proxySSLCert The pathname of a file that stores a client certificate to use to authenticate with an HTTPS proxy. Can be overridden by the GIT_PROXY_SSL_CERT environment variable. http.proxySSLKey The pathname of a file that stores a private key to use to authenticate with an HTTPS proxy. Can be overridden by the GIT_PROXY_SSL_KEY environment variable. http.proxySSLCertPasswordProtected Enable Git's password prompt for the proxy SSL certificate. Otherwise OpenSSL will prompt the user, possibly many times, if the certificate or private key is encrypted. Can be overridden by the GIT_PROXY_SSL_CERT_PASSWORD_PROTECTED environment variable. http.proxySSLCAInfo Pathname to the file containing the certificate bundle that should be used to verify the proxy with when using an HTTPS proxy. Can be overridden by the GIT_PROXY_SSL_CAINFO environment variable. http.emptyAuth Attempt authentication without seeking a username or password. This can be used to attempt GSS-Negotiate authentication without specifying a username in the URL, as libcurl normally requires a username for authentication. http.delegation Control GSSAPI credential delegation. The delegation is disabled by default in libcurl since version 7.21.7. Set parameter to tell the server what it is allowed to delegate when it comes to user credentials. Used with GSS/kerberos. Possible values are: o none - Don't allow any delegation. o policy - Delegates if and only if the OK-AS-DELEGATE flag is set in the Kerberos service ticket, which is a matter of realm policy. o always - Unconditionally allow the server to delegate. http.extraHeader Pass an additional HTTP header when communicating with a server. If more than one such entry exists, all of them are added as extra headers. To allow overriding the settings inherited from the system config, an empty value will reset the extra headers to the empty list. http.cookieFile The pathname of a file containing previously stored cookie lines, which should be used in the Git http session, if they match the server. The file format of the file to read cookies from should be plain HTTP headers or the Netscape/Mozilla cookie file format (see curl(1)). NOTE that the file specified with http.cookieFile is used only as input unless http.saveCookies is set. http.saveCookies If set, store cookies received during requests to the file specified by http.cookieFile. Has no effect if http.cookieFile is unset. http.version Use the specified HTTP protocol version when communicating with a server. If you want to force the default. The available and default version depend on libcurl. Currently the possible values of this option are: o HTTP/2 o HTTP/1.1 http.curloptResolve Hostname resolution information that will be used first by libcurl when sending HTTP requests. This information should be in one of the following formats: o [+]HOST:PORT:ADDRESS[,ADDRESS] o -HOST:PORT The first format redirects all requests to the given HOST:PORT to the provided ADDRESS(s). The second format clears all previous config values for that HOST:PORT combination. To allow easy overriding of all the settings inherited from the system config, an empty value will reset all resolution information to the empty list. http.sslVersion The SSL version to use when negotiating an SSL connection, if you want to force the default. The available and default version depend on whether libcurl was built against NSS or OpenSSL and the particular configuration of the crypto library in use. Internally this sets the CURLOPT_SSL_VERSION option; see the libcurl documentation for more details on the format of this option and for the ssl version supported. Currently the possible values of this option are: o sslv2 o sslv3 o tlsv1 o tlsv1.0 o tlsv1.1 o tlsv1.2 o tlsv1.3 Can be overridden by the GIT_SSL_VERSION environment variable. To force git to use libcurl's default ssl version and ignore any explicit http.sslversion option, set GIT_SSL_VERSION to the empty string. http.sslCipherList A list of SSL ciphers to use when negotiating an SSL connection. The available ciphers depend on whether libcurl was built against NSS or OpenSSL and the particular configuration of the crypto library in use. Internally this sets the CURLOPT_SSL_CIPHER_LIST option; see the libcurl documentation for more details on the format of this list. Can be overridden by the GIT_SSL_CIPHER_LIST environment variable. To force git to use libcurl's default cipher list and ignore any explicit http.sslCipherList option, set GIT_SSL_CIPHER_LIST to the empty string. http.sslVerify Whether to verify the SSL certificate when fetching or pushing over HTTPS. Defaults to true. Can be overridden by the GIT_SSL_NO_VERIFY environment variable. http.sslCert File containing the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CERT environment variable. http.sslKey File containing the SSL private key when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_KEY environment variable. http.sslCertPasswordProtected Enable Git's password prompt for the SSL certificate. Otherwise OpenSSL will prompt the user, possibly many times, if the certificate or private key is encrypted. Can be overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable. http.sslCAInfo File containing the certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable. http.sslCAPath Path containing files with the CA certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable. http.sslBackend Name of the SSL backend to use (e.g. "openssl" or "schannel"). This option is ignored if cURL lacks support for choosing the SSL backend at runtime. http.schannelCheckRevoke Used to enforce or disable certificate revocation checks in cURL when http.sslBackend is set to "schannel". Defaults to true if unset. Only necessary to disable this if Git consistently errors and the message is about checking the revocation status of a certificate. This option is ignored if cURL lacks support for setting the relevant SSL option at runtime. http.schannelUseSSLCAInfo As of cURL v7.60.0, the Secure Channel backend can use the certificate bundle provided via http.sslCAInfo, but that would override the Windows Certificate Store. Since this is not desirable by default, Git will tell cURL not to use that bundle by default when the schannel backend was configured via http.sslBackend, unless http.schannelUseSSLCAInfo overrides this behavior. http.pinnedPubkey Public key of the https service. It may either be the filename of a PEM or DER encoded public key file or a string starting with sha256// followed by the base64 encoded sha256 hash of the public key. See also libcurl CURLOPT_PINNEDPUBLICKEY. git will exit with an error if this option is set but not supported by cURL. http.sslTry Attempt to use AUTH SSL/TLS and encrypted data transfers when connecting via regular FTP protocol. This might be needed if the FTP server requires it for security reasons or you wish to connect securely whenever remote FTP server supports it. Default is false since it might trigger certificate verification errors on misconfigured servers. http.maxRequests How many HTTP requests to launch in parallel. Can be overridden by the GIT_HTTP_MAX_REQUESTS environment variable. Default is 5. http.minSessions The number of curl sessions (counted across slots) to be kept across requests. They will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1. http.postBuffer Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests. Note that raising this limit is only effective for disabling chunked transfer encoding and therefore should be used only where the remote server or a proxy only supports HTTP/1.0 or is noncompliant with the HTTP standard. Raising this is not, in general, an effective solution for most push problems, but can increase memory consumption significantly since the entire buffer is allocated even for small pushes. http.lowSpeedLimit, http.lowSpeedTime If the HTTP transfer speed, in bytes per second, is less than http.lowSpeedLimit for longer than http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by the GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables. http.noEPSV A boolean which disables using of EPSV ftp command by curl. This can be helpful with some "poor" ftp servers which don't support EPSV mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV). http.userAgent The HTTP USER_AGENT string presented to an HTTP server. The default value represents the version of the Git client such as git/1.7.1. This option allows you to override this value to a more common value such as Mozilla/4.0. This may be necessary, for instance, if connecting through a firewall that restricts HTTP connections to a set of common USER_AGENT strings (but not including those like git/1.7.1). Can be overridden by the GIT_HTTP_USER_AGENT environment variable. http.followRedirects Whether git should follow HTTP redirects. If set to true, git will transparently follow any redirect issued by a server it encounters. If set to false, git will treat all redirects as errors. If set to initial, git will follow redirects only for the initial request to a remote, but not for subsequent follow-up HTTP requests. Since git uses the redirected URL as the base for the follow-up requests, this is generally sufficient. The default is initial. http..* Any of the http.* options above can be applied selectively to some URLs. For a config key to match a URL, each element of the config key is compared to that of the URL, in the following order: 1. Scheme (e.g., https in https://example.com/). This field must match exactly between the config key and the URL. 2. Host/domain name (e.g., example.com in https://example.com/). This field must match between the config key and the URL. It is possible to specify a * as part of the host name to match all subdomains at this level. https://*.example.com/ for example would match https://foo.example.com/, but not https://foo.bar.example.com/. 3. Port number (e.g., 8080 in http://example.com:8080/). This field must match exactly between the config key and the URL. Omitted port numbers are automatically converted to the correct default for the scheme before matching. 4. Path (e.g., repo.git in https://example.com/repo.git). The path field of the config key must match the path field of the URL either exactly or as a prefix of slash-delimited path elements. This means a config key with path foo/ matches URL path foo/bar. A prefix can only match on a slash (/) boundary. Longer matches take precedence (so a config key with path foo/bar is a better match to URL path foo/bar than a config key with just path foo/). 5. User name (e.g., user in https://user@example.com/repo.git). If the config key has a user name it must match the user name in the URL exactly. If the config key does not have a user name, that config key will match a URL with any user name (including none), but at a lower precedence than a config key with a user name. The list above is ordered by decreasing precedence; a URL that matches a config key's path is preferred to one that matches its user name. For example, if the URL is https://user@example.com/foo/bar a config key match of https://example.com/foo will be preferred over a config key match of https://user@example.com. All URLs are normalized before attempting any matching (the password part, if embedded in the URL, is always ignored for matching purposes) so that equivalent URLs that are simply spelled differently will match properly. Environment variable settings always override any matches. The URLs that are matched against are those given directly to Git commands. This means any URLs visited as a result of a redirection do not participate in matching. i18n.commitEncoding Character encoding the commit messages are stored in; Git itself does not care per se, but this information is necessary e.g. when importing commits from emails or in the gitk graphical history browser (and possibly in other places in the future or in other porcelains). See e.g. git-mailinfo(1). Defaults to utf-8. i18n.logOutputEncoding Character encoding the commit messages are converted to when running git log and friends. imap.folder The folder to drop the mails into, which is typically the Drafts folder. For example: "INBOX.Drafts", "INBOX/Drafts" or "[Gmail]/Drafts". Required. imap.tunnel Command used to set up a tunnel to the IMAP server through which commands will be piped instead of using a direct network connection to the server. Required when imap.host is not set. imap.host A URL identifying the server. Use an imap:// prefix for non-secure connections and an imaps:// prefix for secure connections. Ignored when imap.tunnel is set, but required otherwise. imap.user The username to use when logging in to the server. imap.pass The password to use when logging in to the server. imap.port An integer port number to connect to on the server. Defaults to 143 for imap:// hosts and 993 for imaps:// hosts. Ignored when imap.tunnel is set. imap.sslverify A boolean to enable/disable verification of the server certificate used by the SSL/TLS connection. Default is true. Ignored when imap.tunnel is set. imap.preformattedHTML A boolean to enable/disable the use of html encoding when sending a patch. An html encoded patch will be bracketed with 
 and have
           a content type of text/html. Ironically, enabling this option
           causes Thunderbird to send the patch as a plain/text, format=fixed
           email. Default is false.

       imap.authMethod
           Specify the authentication method for authenticating with the IMAP
           server. If Git was built with the NO_CURL option, or if your curl
           version is older than 7.34.0, or if you're running git-imap-send
           with the --no-curl option, the only supported method is CRAM-MD5.
           If this is not set then git imap-send uses the basic IMAP plaintext
           LOGIN command.

       include.path, includeIf..path
           Special variables to include other configuration files. See the
           "CONFIGURATION FILE" section in the main git-config(1)
           documentation, specifically the "Includes" and "Conditional
           Includes" subsections.

       index.recordEndOfIndexEntries
           Specifies whether the index file should include an "End Of Index
           Entry" section. This reduces index load time on multiprocessor
           machines but produces a message "ignoring EOIE extension" when
           reading the index using Git versions before 2.20. Defaults to true
           if index.threads has been explicitly enabled, false otherwise.

       index.recordOffsetTable
           Specifies whether the index file should include an "Index Entry
           Offset Table" section. This reduces index load time on
           multiprocessor machines but produces a message "ignoring IEOT
           extension" when reading the index using Git versions before 2.20.
           Defaults to true if index.threads has been explicitly enabled,
           false otherwise.

       index.sparse
           When enabled, write the index using sparse-directory entries. This
           has no effect unless core.sparseCheckout and
           core.sparseCheckoutCone are both enabled. Defaults to false.

       index.threads
           Specifies the number of threads to spawn when loading the index.
           This is meant to reduce index load time on multiprocessor machines.
           Specifying 0 or true will cause Git to auto-detect the number of
           CPUs and set the number of threads accordingly. Specifying 1 or
           false will disable multithreading. Defaults to true.

       index.version
           Specify the version with which new index files should be
           initialized. This does not affect existing repositories. If
           feature.manyFiles is enabled, then the default is 4.

       index.skipHash
           When enabled, do not compute the trailing hash for the index file.
           This accelerates Git commands that manipulate the index, such as
           git add, git commit, or git status. Instead of storing the
           checksum, write a trailing set of bytes with value zero, indicating
           that the computation was skipped.

           If you enable index.skipHash, then Git clients older than 2.13.0
           will refuse to parse the index and Git clients older than 2.40.0
           will report an error during git fsck.

       init.templateDir
           Specify the directory from which templates will be copied. (See the
           "TEMPLATE DIRECTORY" section of git-init(1).)

       init.defaultBranch
           Allows overriding the default branch name e.g. when initializing a
           new repository.

       instaweb.browser
           Specify the program that will be used to browse your working
           repository in gitweb. See git-instaweb(1).

       instaweb.httpd
           The HTTP daemon command-line to start gitweb on your working
           repository. See git-instaweb(1).

       instaweb.local
           If true the web server started by git-instaweb(1) will be bound to
           the local IP (127.0.0.1).

       instaweb.modulePath
           The default module path for git-instaweb(1) to use instead of
           /usr/lib/apache2/modules. Only used if httpd is Apache.

       instaweb.port
           The port number to bind the gitweb httpd to. See git-instaweb(1).

       interactive.singleKey
           In interactive commands, allow the user to provide one-letter input
           with a single key (i.e., without hitting enter). Currently this is
           used by the --patch mode of git-add(1), git-checkout(1), git-
           restore(1), git-commit(1), git-reset(1), and git-stash(1).

       interactive.diffFilter
           When an interactive command (such as git add --patch) shows a
           colorized diff, git will pipe the diff through the shell command
           defined by this configuration variable. The command may mark up the
           diff further for human consumption, provided that it retains a
           one-to-one correspondence with the lines in the original diff.
           Defaults to disabled (no filtering).

       log.abbrevCommit
           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
           assume --abbrev-commit. You may override this option with
           --no-abbrev-commit.

       log.date
           Set the default date-time mode for the log command. Setting a value
           for log.date is similar to using git log's --date option. See git-
           log(1) for details.

           If the format is set to "auto:foo" and the pager is in use, format
           "foo" will be used for the date format. Otherwise, "default" will
           be used.

       log.decorate
           Print out the ref names of any commits that are shown by the log
           command. If short is specified, the ref name prefixes refs/heads/,
           refs/tags/ and refs/remotes/ will not be printed. If full is
           specified, the full ref name (including prefix) will be printed. If
           auto is specified, then if the output is going to a terminal, the
           ref names are shown as if short were given, otherwise no ref names
           are shown. This is the same as the --decorate option of the git
           log.

       log.initialDecorationSet
           By default, git log only shows decorations for certain known ref
           namespaces. If all is specified, then show all refs as decorations.

       log.excludeDecoration
           Exclude the specified patterns from the log decorations. This is
           similar to the --decorate-refs-exclude command-line option, but the
           config option can be overridden by the --decorate-refs option.

       log.diffMerges
           Set diff format to be used when --diff-merges=on is specified, see
           --diff-merges in git-log(1) for details. Defaults to separate.

       log.follow
           If true, git log will act as if the --follow option was used when a
           single  is given. This has the same limitations as --follow,
           i.e. it cannot be used to follow multiple files and does not work
           well on non-linear history.

       log.graphColors
           A list of colors, separated by commas, that can be used to draw
           history lines in git log --graph.

       log.showRoot
           If true, the initial commit will be shown as a big creation event.
           This is equivalent to a diff against an empty tree. Tools like git-
           log(1) or git-whatchanged(1), which normally hide the root commit
           will now show it. True by default.

       log.showSignature
           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
           assume --show-signature.

       log.mailmap
           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
           assume --use-mailmap, otherwise assume --no-use-mailmap. True by
           default.

       lsrefs.unborn
           May be "advertise" (the default), "allow", or "ignore". If
           "advertise", the server will respond to the client sending "unborn"
           (as described in gitprotocol-v2(5)) and will advertise support for
           this feature during the protocol v2 capability advertisement.
           "allow" is the same as "advertise" except that the server will not
           advertise support for this feature; this is useful for
           load-balanced servers that cannot be updated atomically (for
           example), since the administrator could configure "allow", then
           after a delay, configure "advertise".

       mailinfo.scissors
           If true, makes git-mailinfo(1) (and therefore git-am(1)) act by
           default as if the --scissors option was provided on the
           command-line. When active, this feature removes everything from the
           message body before a scissors line (i.e. consisting mainly of
           ">8", "8<" and "-").

       mailmap.file
           The location of an augmenting mailmap file. The default mailmap,
           located in the root of the repository, is loaded first, then the
           mailmap file pointed to by this variable. The location of the
           mailmap file may be in a repository subdirectory, or somewhere
           outside of the repository itself. See git-shortlog(1) and git-
           blame(1).

       mailmap.blob
           Like mailmap.file, but consider the value as a reference to a blob
           in the repository. If both mailmap.file and mailmap.blob are given,
           both are parsed, with entries from mailmap.file taking precedence.
           In a bare repository, this defaults to HEAD:.mailmap. In a non-bare
           repository, it defaults to empty.

       maintenance.auto
           This boolean config option controls whether some commands run git
           maintenance run --auto after doing their normal work. Defaults to
           true.

       maintenance.strategy
           This string config option provides a way to specify one of a few
           recommended schedules for background maintenance. This only affects
           which tasks are run during git maintenance run --schedule=X
           commands, provided no --task= arguments are provided.
           Further, if a maintenance..schedule config value is set, then
           that value is used instead of the one provided by
           maintenance.strategy. The possible strategy strings are:

           o   none: This default setting implies no tasks are run at any
               schedule.

           o   incremental: This setting optimizes for performing small
               maintenance activities that do not delete any data. This does
               not schedule the gc task, but runs the prefetch and
               commit-graph tasks hourly, the loose-objects and
               incremental-repack tasks daily, and the pack-refs task weekly.

       maintenance..enabled
           This boolean config option controls whether the maintenance task
           with name  is run when no --task option is specified to git
           maintenance run. These config values are ignored if a --task option
           exists. By default, only maintenance.gc.enabled is true.

       maintenance..schedule
           This config option controls whether or not the given  runs
           during a git maintenance run --schedule= command. The
           value must be one of "hourly", "daily", or "weekly".

       maintenance.commit-graph.auto
           This integer config option controls how often the commit-graph task
           should be run as part of git maintenance run --auto. If zero, then
           the commit-graph task will not run with the --auto option. A
           negative value will force the task to run every time. Otherwise, a
           positive value implies the command should run when the number of
           reachable commits that are not in the commit-graph file is at least
           the value of maintenance.commit-graph.auto. The default value is
           100.

       maintenance.loose-objects.auto
           This integer config option controls how often the loose-objects
           task should be run as part of git maintenance run --auto. If zero,
           then the loose-objects task will not run with the --auto option. A
           negative value will force the task to run every time. Otherwise, a
           positive value implies the command should run when the number of
           loose objects is at least the value of
           maintenance.loose-objects.auto. The default value is 100.

       maintenance.incremental-repack.auto
           This integer config option controls how often the
           incremental-repack task should be run as part of git maintenance
           run --auto. If zero, then the incremental-repack task will not run
           with the --auto option. A negative value will force the task to run
           every time. Otherwise, a positive value implies the command should
           run when the number of pack-files not in the multi-pack-index is at
           least the value of maintenance.incremental-repack.auto. The default
           value is 10.

       man.viewer
           Specify the programs that may be used to display help in the man
           format. See git-help(1).

       man..cmd
           Specify the command to invoke the specified man viewer. The
           specified command is evaluated in shell with the man page passed as
           an argument. (See git-help(1).)

       man..path
           Override the path for the given tool that may be used to display
           help in the man format. See git-help(1).

       merge.conflictStyle
           Specify the style in which conflicted hunks are written out to
           working tree files upon merge. The default is "merge", which shows
           a <<<<<<< conflict marker, changes made by one side, a =======
           marker, changes made by the other side, and then a >>>>>>> marker.
           An alternate style, "diff3", adds a ||||||| marker and the original
           text before the ======= marker. The "merge" style tends to produce
           smaller conflict regions than diff3, both because of the exclusion
           of the original text, and because when a subset of lines match on
           the two sides, they are just pulled out of the conflict region.
           Another alternate style, "zdiff3", is similar to diff3 but removes
           matching lines on the two sides from the conflict region when those
           matching lines appear near either the beginning or end of a
           conflict region.

       merge.defaultToUpstream
           If merge is called without any commit argument, merge the upstream
           branches configured for the current branch by using their last
           observed values stored in their remote-tracking branches. The
           values of the branch..merge that name the branches
           at the remote named by branch..remote are
           consulted, and then they are mapped via remote..fetch to
           their corresponding remote-tracking branches, and the tips of these
           tracking branches are merged. Defaults to true.

       merge.ff
           By default, Git does not create an extra merge commit when merging
           a commit that is a descendant of the current commit. Instead, the
           tip of the current branch is fast-forwarded. When set to false,
           this variable tells Git to create an extra merge commit in such a
           case (equivalent to giving the --no-ff option from the command
           line). When set to only, only such fast-forward merges are allowed
           (equivalent to giving the --ff-only option from the command line).

       merge.verifySignatures
           If true, this is equivalent to the --verify-signatures command line
           option. See git-merge(1) for details.

       merge.branchdesc
           In addition to branch names, populate the log message with the
           branch description text associated with them. Defaults to false.

       merge.log
           In addition to branch names, populate the log message with at most
           the specified number of one-line descriptions from the actual
           commits that are being merged. Defaults to false, and true is a
           synonym for 20.

       merge.suppressDest
           By adding a glob that matches the names of integration branches to
           this multi-valued configuration variable, the default merge message
           computed for merges into these integration branches will omit "into
           " from its title.

           An element with an empty value can be used to clear the list of
           globs accumulated from previous configuration entries. When there
           is no merge.suppressDest variable defined, the default value of
           master is used for backward compatibility.

       merge.renameLimit
           The number of files to consider in the exhaustive portion of rename
           detection during a merge. If not specified, defaults to the value
           of diff.renameLimit. If neither merge.renameLimit nor
           diff.renameLimit are specified, currently defaults to 7000. This
           setting has no effect if rename detection is turned off.

       merge.renames
           Whether Git detects renames. If set to "false", rename detection is
           disabled. If set to "true", basic rename detection is enabled.
           Defaults to the value of diff.renames.

       merge.directoryRenames
           Whether Git detects directory renames, affecting what happens at
           merge time to new files added to a directory on one side of history
           when that directory was renamed on the other side of history. If
           merge.directoryRenames is set to "false", directory rename
           detection is disabled, meaning that such new files will be left
           behind in the old directory. If set to "true", directory rename
           detection is enabled, meaning that such new files will be moved
           into the new directory. If set to "conflict", a conflict will be
           reported for such paths. If merge.renames is false,
           merge.directoryRenames is ignored and treated as false. Defaults to
           "conflict".

       merge.renormalize
           Tell Git that canonical representation of files in the repository
           has changed over time (e.g. earlier commits record text files with
           CRLF line endings, but recent ones use LF line endings). In such a
           repository, Git can convert the data recorded in commits to a
           canonical form before performing a merge to reduce unnecessary
           conflicts. For more information, see section "Merging branches with
           differing checkin/checkout attributes" in gitattributes(5).

       merge.stat
           Whether to print the diffstat between ORIG_HEAD and the merge
           result at the end of the merge. True by default.

       merge.autoStash
           When set to true, automatically create a temporary stash entry
           before the operation begins, and apply it after the operation ends.
           This means that you can run merge on a dirty worktree. However, use
           with care: the final stash application after a successful merge
           might result in non-trivial conflicts. This option can be
           overridden by the --no-autostash and --autostash options of git-
           merge(1). Defaults to false.

       merge.tool
           Controls which merge tool is used by git-mergetool(1). The list
           below shows the valid built-in values. Any other value is treated
           as a custom merge tool and requires that a corresponding
           mergetool..cmd variable is defined.

       merge.guitool
           Controls which merge tool is used by git-mergetool(1) when the
           -g/--gui flag is specified. The list below shows the valid built-in
           values. Any other value is treated as a custom merge tool and
           requires that a corresponding mergetool..cmd variable is
           defined.

       merge.verbosity
           Controls the amount of output shown by the recursive merge
           strategy. Level 0 outputs nothing except a final error message if
           conflicts were detected. Level 1 outputs only conflicts, 2 outputs
           conflicts and file changes. Level 5 and above outputs debugging
           information. The default is level 2. Can be overridden by the
           GIT_MERGE_VERBOSITY environment variable.

       merge..name
           Defines a human-readable name for a custom low-level merge driver.
           See gitattributes(5) for details.

       merge..driver
           Defines the command that implements a custom low-level merge
           driver. See gitattributes(5) for details.

       merge..recursive
           Names a low-level merge driver to be used when performing an
           internal merge between common ancestors. See gitattributes(5) for
           details.

       mergetool..path
           Override the path for the given tool. This is useful in case your
           tool is not in the PATH.

       mergetool..cmd
           Specify the command to invoke the specified merge tool. The
           specified command is evaluated in shell with the following
           variables available: BASE is the name of a temporary file
           containing the common base of the files to be merged, if available;
           LOCAL is the name of a temporary file containing the contents of
           the file on the current branch; REMOTE is the name of a temporary
           file containing the contents of the file from the branch being
           merged; MERGED contains the name of the file to which the merge
           tool should write the results of a successful merge.

       mergetool..hideResolved
           Allows the user to override the global mergetool.hideResolved value
           for a specific tool. See mergetool.hideResolved for the full
           description.

       mergetool..trustExitCode
           For a custom merge command, specify whether the exit code of the
           merge command can be used to determine whether the merge was
           successful. If this is not set to true then the merge target file
           timestamp is checked, and the merge is assumed to have been
           successful if the file has been updated; otherwise, the user is
           prompted to indicate the success of the merge.

       mergetool.meld.hasOutput
           Older versions of meld do not support the --output option. Git will
           attempt to detect whether meld supports --output by inspecting the
           output of meld --help. Configuring mergetool.meld.hasOutput will
           make Git skip these checks and use the configured value instead.
           Setting mergetool.meld.hasOutput to true tells Git to
           unconditionally use the --output option, and false avoids using
           --output.

       mergetool.meld.useAutoMerge
           When the --auto-merge is given, meld will merge all non-conflicting
           parts automatically, highlight the conflicting parts, and wait for
           user decision. Setting mergetool.meld.useAutoMerge to true tells
           Git to unconditionally use the --auto-merge option with meld.
           Setting this value to auto makes git detect whether --auto-merge is
           supported and will only use --auto-merge when available. A value of
           false avoids using --auto-merge altogether, and is the default
           value.

       mergetool..layout
           Configure the split window layout for vimdiff's , which is
           any of vimdiff, nvimdiff, gvimdiff. Upon launching git mergetool
           with --tool= (or without --tool if merge.tool is
           configured as ), Git will consult
           mergetool..layout to determine the tool's layout. If the
           variant-specific configuration is not available, vimdiff's is used
           as fallback. If that too is not available, a default layout with 4
           windows will be used. To configure the layout, see the BACKEND
           SPECIFIC HINTS section in git-mergetool(1).

       mergetool.hideResolved
           During a merge, Git will automatically resolve as many conflicts as
           possible and write the MERGED file containing conflict markers
           around any conflicts that it cannot resolve; LOCAL and REMOTE
           normally represent the versions of the file from before Git's
           conflict resolution. This flag causes LOCAL and REMOTE to be
           overwritten so that only the unresolved conflicts are presented to
           the merge tool. Can be configured per-tool via the
           mergetool..hideResolved configuration variable. Defaults to
           false.

       mergetool.keepBackup
           After performing a merge, the original file with conflict markers
           can be saved as a file with a .orig extension. If this variable is
           set to false then this file is not preserved. Defaults to true
           (i.e. keep the backup files).

       mergetool.keepTemporaries
           When invoking a custom merge tool, Git uses a set of temporary
           files to pass to the tool. If the tool returns an error and this
           variable is set to true, then these temporary files will be
           preserved; otherwise, they will be removed after the tool has
           exited. Defaults to false.

       mergetool.writeToTemp
           Git writes temporary BASE, LOCAL, and REMOTE versions of
           conflicting files in the worktree by default. Git will attempt to
           use a temporary directory for these files when set true. Defaults
           to false.

       mergetool.prompt
           Prompt before each invocation of the merge resolution program.

       mergetool.guiDefault
           Set true to use the merge.guitool by default (equivalent to
           specifying the --gui argument), or auto to select merge.guitool or
           merge.tool depending on the presence of a DISPLAY environment
           variable value. The default is false, where the --gui argument must
           be provided explicitly for the merge.guitool to be used.

       notes.mergeStrategy
           Which merge strategy to choose by default when resolving notes
           conflicts. Must be one of manual, ours, theirs, union, or
           cat_sort_uniq. Defaults to manual. See the "NOTES MERGE STRATEGIES"
           section of git-notes(1) for more information on each strategy.

           This setting can be overridden by passing the --strategy option to
           git-notes(1).

       notes..mergeStrategy
           Which merge strategy to choose when doing a notes merge into
           refs/notes/. This overrides the more general
           "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES" section in
           git-notes(1) for more information on the available strategies.

       notes.displayRef
           Which ref (or refs, if a glob or specified more than once), in
           addition to the default set by core.notesRef or GIT_NOTES_REF, to
           read notes from when showing commit messages with the git log
           family of commands.

           This setting can be overridden with the GIT_NOTES_DISPLAY_REF
           environment variable, which must be a colon separated list of refs
           or globs.

           A warning will be issued for refs that do not exist, but a glob
           that does not match any refs is silently ignored.

           This setting can be disabled by the --no-notes option to the git
           log family of commands, or by the --notes= option accepted by
           those commands.

           The effective value of "core.notesRef" (possibly overridden by
           GIT_NOTES_REF) is also implicitly added to the list of refs to be
           displayed.

       notes.rewrite.
           When rewriting commits with  (currently amend or rebase),
           if this variable is false, git will not copy notes from the
           original to the rewritten commit. Defaults to true. See also
           "notes.rewriteRef" below.

           This setting can be overridden with the GIT_NOTES_REWRITE_REF
           environment variable, which must be a colon separated list of refs
           or globs.

       notes.rewriteMode
           When copying notes during a rewrite (see the
           "notes.rewrite." option), determines what to do if the
           target commit already has a note. Must be one of overwrite,
           concatenate, cat_sort_uniq, or ignore. Defaults to concatenate.

           This setting can be overridden with the GIT_NOTES_REWRITE_MODE
           environment variable.

       notes.rewriteRef
           When copying notes during a rewrite, specifies the (fully
           qualified) ref whose notes should be copied. May be a glob, in
           which case notes in all matching refs will be copied. You may also
           specify this configuration several times.

           Does not have a default value; you must configure this variable to
           enable note rewriting. Set it to refs/notes/commits to enable
           rewriting for the default commit notes.

           Can be overridden with the GIT_NOTES_REWRITE_REF environment
           variable. See notes.rewrite. above for a further
           description of its format.

       pack.window
           The size of the window used by git-pack-objects(1) when no window
           size is given on the command line. Defaults to 10.

       pack.depth
           The maximum delta depth used by git-pack-objects(1) when no maximum
           depth is given on the command line. Defaults to 50. Maximum value
           is 4095.

       pack.windowMemory
           The maximum size of memory that is consumed by each thread in git-
           pack-objects(1) for pack window memory when no limit is given on
           the command line. The value can be suffixed with "k", "m", or "g".
           When left unconfigured (or set explicitly to 0), there will be no
           limit.

       pack.compression
           An integer -1..9, indicating the compression level for objects in a
           pack file. -1 is the zlib default. 0 means no compression, and 1..9
           are various speed/size tradeoffs, 9 being slowest. If not set,
           defaults to core.compression. If that is not set, defaults to -1,
           the zlib default, which is "a default compromise between speed and
           compression (currently equivalent to level 6)."

           Note that changing the compression level will not automatically
           recompress all existing objects. You can force recompression by
           passing the -F option to git-repack(1).

       pack.allowPackReuse
           When true or "single", and when reachability bitmaps are enabled,
           pack-objects will try to send parts of the bitmapped packfile
           verbatim. When "multi", and when a multi-pack reachability bitmap
           is available, pack-objects will try to send parts of all packs in
           the MIDX.

           If only a single pack bitmap is available, and pack.allowPackReuse
           is set to "multi", reuse parts of just the bitmapped packfile. This
           can reduce memory and CPU usage to serve fetches, but might result
           in sending a slightly larger pack. Defaults to true.

       pack.island
           An extended regular expression configuring a set of delta islands.
           See "DELTA ISLANDS" in git-pack-objects(1) for details.

       pack.islandCore
           Specify an island name which gets to have its objects be packed
           first. This creates a kind of pseudo-pack at the front of one pack,
           so that the objects from the specified island are hopefully faster
           to copy into any pack that should be served to a user requesting
           these objects. In practice this means that the island specified
           should likely correspond to what is the most commonly cloned in the
           repo. See also "DELTA ISLANDS" in git-pack-objects(1).

       pack.deltaCacheSize
           The maximum memory in bytes used for caching deltas in git-pack-
           objects(1) before writing them out to a pack. This cache is used to
           speed up the writing object phase by not having to recompute the
           final delta result once the best match for all objects is found.
           Repacking large repositories on machines which are tight with
           memory might be badly impacted by this though, especially if this
           cache pushes the system into swapping. A value of 0 means no limit.
           The smallest size of 1 byte may be used to virtually disable this
           cache. Defaults to 256 MiB.

       pack.deltaCacheLimit
           The maximum size of a delta, that is cached in git-pack-objects(1).
           This cache is used to speed up the writing object phase by not
           having to recompute the final delta result once the best match for
           all objects is found. Defaults to 1000. Maximum value is 65535.

       pack.threads
           Specifies the number of threads to spawn when searching for best
           delta matches. This requires that git-pack-objects(1) be compiled
           with pthreads otherwise this option is ignored with a warning. This
           is meant to reduce packing time on multiprocessor machines. The
           required amount of memory for the delta search window is however
           multiplied by the number of threads. Specifying 0 will cause Git to
           auto-detect the number of CPUs and set the number of threads
           accordingly.

       pack.indexVersion
           Specify the default pack index version. Valid values are 1 for
           legacy pack index used by Git versions prior to 1.5.2, and 2 for
           the new pack index with capabilities for packs larger than 4 GB as
           well as proper protection against the repacking of corrupted packs.
           Version 2 is the default. Note that version 2 is enforced and this
           config option is ignored whenever the corresponding pack is larger
           than 2 GB.

           If you have an old Git that does not understand the version 2 *.idx
           file, cloning or fetching over a non-native protocol (e.g. "http")
           that will copy both *.pack file and corresponding *.idx file from
           the other side may give you a repository that cannot be accessed
           with your older version of Git. If the *.pack file is smaller than
           2 GB, however, you can use git-index-pack(1) on the *.pack file to
           regenerate the *.idx file.

       pack.packSizeLimit
           The maximum size of a pack. This setting only affects packing to a
           file when repacking, i.e. the git:// protocol is unaffected. It can
           be overridden by the --max-pack-size option of git-repack(1).
           Reaching this limit results in the creation of multiple packfiles.

           Note that this option is rarely useful, and may result in a larger
           total on-disk size (because Git will not store deltas between
           packs) and worse runtime performance (object lookup within multiple
           packs is slower than a single pack, and optimizations like
           reachability bitmaps cannot cope with multiple packs).

           If you need to actively run Git using smaller packfiles (e.g.,
           because your filesystem does not support large files), this option
           may help. But if your goal is to transmit a packfile over a medium
           that supports limited sizes (e.g., removable media that cannot
           store the whole repository), you are likely better off creating a
           single large packfile and splitting it using a generic multi-volume
           archive tool (e.g., Unix split).

           The minimum size allowed is limited to 1 MiB. The default is
           unlimited. Common unit suffixes of k, m, or g are supported.

       pack.useBitmaps
           When true, git will use pack bitmaps (if available) when packing to
           stdout (e.g., during the server side of a fetch). Defaults to true.
           You should not generally need to turn this off unless you are
           debugging pack bitmaps.

       pack.useBitmapBoundaryTraversal
           When true, Git will use an experimental algorithm for computing
           reachability queries with bitmaps. Instead of building up complete
           bitmaps for all of the negated tips and then OR-ing them together,
           consider negated tips with existing bitmaps as additive (i.e.
           OR-ing them into the result if they exist, ignoring them
           otherwise), and build up a bitmap at the boundary instead.

           When using this algorithm, Git may include too many objects as a
           result of not opening up trees belonging to certain UNINTERESTING
           commits. This inexactness matches the non-bitmap traversal
           algorithm.

           In many cases, this can provide a speed-up over the exact
           algorithm, particularly when there is poor bitmap coverage of the
           negated side of the query.

       pack.useSparse
           When true, git will default to using the --sparse option in git
           pack-objects when the --revs option is present. This algorithm only
           walks trees that appear in paths that introduce new objects. This
           can have significant performance benefits when computing a pack to
           send a small change. However, it is possible that extra objects are
           added to the pack-file if the included commits contain certain
           types of direct renames. Default is true.

       pack.preferBitmapTips
           When selecting which commits will receive bitmaps, prefer a commit
           at the tip of any reference that is a suffix of any value of this
           configuration over any other commits in the "selection window".

           Note that setting this configuration to refs/foo does not mean that
           the commits at the tips of refs/foo/bar and refs/foo/baz will
           necessarily be selected. This is because commits are selected for
           bitmaps from within a series of windows of variable length.

           If a commit at the tip of any reference which is a suffix of any
           value of this configuration is seen in a window, it is immediately
           given preference over any other commit in that window.

       pack.writeBitmaps (deprecated)
           This is a deprecated synonym for repack.writeBitmaps.

       pack.writeBitmapHashCache
           When true, git will include a "hash cache" section in the bitmap
           index (if one is written). This cache can be used to feed git's
           delta heuristics, potentially leading to better deltas between
           bitmapped and non-bitmapped objects (e.g., when serving a fetch
           between an older, bitmapped pack and objects that have been pushed
           since the last gc). The downside is that it consumes 4 bytes per
           object of disk space. Defaults to true.

           When writing a multi-pack reachability bitmap, no new namehashes
           are computed; instead, any namehashes stored in an existing bitmap
           are permuted into their appropriate location when writing a new
           bitmap.

       pack.writeBitmapLookupTable
           When true, Git will include a "lookup table" section in the bitmap
           index (if one is written). This table is used to defer loading
           individual bitmaps as late as possible. This can be beneficial in
           repositories that have relatively large bitmap indexes. Defaults to
           false.

       pack.readReverseIndex
           When true, git will read any .rev file(s) that may be available
           (see: gitformat-pack(5)). When false, the reverse index will be
           generated from scratch and stored in memory. Defaults to true.

       pack.writeReverseIndex
           When true, git will write a corresponding .rev file (see:
           gitformat-pack(5)) for each new packfile that it writes in all
           places except for git-fast-import(1) and in the bulk checkin
           mechanism. Defaults to true.

       pager.
           If the value is boolean, turns on or off pagination of the output
           of a particular Git subcommand when writing to a tty. Otherwise,
           turns on pagination for the subcommand using the pager specified by
           the value of pager.. If --paginate or --no-pager is specified
           on the command line, it takes precedence over this option. To
           disable pagination for all commands, set core.pager or GIT_PAGER to
           cat.

       pretty.
           Alias for a --pretty= format string, as specified in git-log(1).
           Any aliases defined here can be used just as the built-in pretty
           formats could. For example, running git config pretty.changelog
           "format:* %H %s" would cause the invocation git log
           --pretty=changelog to be equivalent to running git log
           "--pretty=format:* %H %s". Note that an alias with the same name as
           a built-in format will be silently ignored.

       protocol.allow
           If set, provide a user defined default policy for all protocols
           which don't explicitly have a policy (protocol..allow). By
           default, if unset, known-safe protocols (http, https, git, ssh)
           have a default policy of always, known-dangerous protocols (ext)
           have a default policy of never, and all other protocols (including
           file) have a default policy of user. Supported policies:

           o   always - protocol is always able to be used.

           o   never - protocol is never able to be used.

           o   user - protocol is only able to be used when
               GIT_PROTOCOL_FROM_USER is either unset or has a value of 1.
               This policy should be used when you want a protocol to be
               directly usable by the user but don't want it used by commands
               which execute clone/fetch/push commands without user input,
               e.g. recursive submodule initialization.

       protocol..allow
           Set a policy to be used by protocol  with clone/fetch/push
           commands. See protocol.allow above for the available policies.

           The protocol names currently used by git are:

           o   file: any local file-based path (including file:// URLs, or
               local paths)

           o   git: the anonymous git protocol over a direct TCP connection
               (or proxy, if configured)

           o   ssh: git over ssh (including host:path syntax, ssh://, etc).

           o   http: git over http, both "smart http" and "dumb http". Note
               that this does not include https; if you want to configure
               both, you must do so individually.

           o   any external helpers are named by their protocol (e.g., use hg
               to allow the git-remote-hg helper)

       protocol.version
           If set, clients will attempt to communicate with a server using the
           specified protocol version. If the server does not support it,
           communication falls back to version 0. If unset, the default is 2.
           Supported versions:

           o   0 - the original wire protocol.

           o   1 - the original wire protocol with the addition of a version
               string in the initial response from the server.

           o   2 - Wire protocol version 2, see gitprotocol-v2(5).

       pull.ff
           By default, Git does not create an extra merge commit when merging
           a commit that is a descendant of the current commit. Instead, the
           tip of the current branch is fast-forwarded. When set to false,
           this variable tells Git to create an extra merge commit in such a
           case (equivalent to giving the --no-ff option from the command
           line). When set to only, only such fast-forward merges are allowed
           (equivalent to giving the --ff-only option from the command line).
           This setting overrides merge.ff when pulling.

       pull.rebase
           When true, rebase branches on top of the fetched branch, instead of
           merging the default branch from the default remote when "git pull"
           is run. See "branch..rebase" for setting this on a per-branch
           basis.

           When merges (or just m), pass the --rebase-merges option to git
           rebase so that the local merge commits are included in the rebase
           (see git-rebase(1) for details).

           When the value is interactive (or just i), the rebase is run in
           interactive mode.

           NOTE: this is a possibly dangerous operation; do not use it unless
           you understand the implications (see git-rebase(1) for details).

       pull.octopus
           The default merge strategy to use when pulling multiple branches at
           once.

       pull.twohead
           The default merge strategy to use when pulling a single branch.

       push.autoSetupRemote
           If set to "true" assume --set-upstream on default push when no
           upstream tracking exists for the current branch; this option takes
           effect with push.default options simple, upstream, and current. It
           is useful if by default you want new branches to be pushed to the
           default remote (like the behavior of push.default=current) and you
           also want the upstream tracking to be set. Workflows most likely to
           benefit from this option are simple central workflows where all
           branches are expected to have the same name on the remote.

       push.default
           Defines the action git push should take if no refspec is given
           (whether from the command-line, config, or elsewhere). Different
           values are well-suited for specific workflows; for instance, in a
           purely central workflow (i.e. the fetch source is equal to the push
           destination), upstream is probably what you want. Possible values
           are:

           o   nothing - do not push anything (error out) unless a refspec is
               given. This is primarily meant for people who want to avoid
               mistakes by always being explicit.

           o   current - push the current branch to update a branch with the
               same name on the receiving end. Works in both central and
               non-central workflows.

           o   upstream - push the current branch back to the branch whose
               changes are usually integrated into the current branch (which
               is called @{upstream}). This mode only makes sense if you are
               pushing to the same repository you would normally pull from
               (i.e. central workflow).

           o   tracking - This is a deprecated synonym for upstream.

           o   simple - push the current branch with the same name on the
               remote.

               If you are working on a centralized workflow (pushing to the
               same repository you pull from, which is typically origin), then
               you need to configure an upstream branch with the same name.

               This mode is the default since Git 2.0, and is the safest
               option suited for beginners.

           o   matching - push all branches having the same name on both ends.
               This makes the repository you are pushing to remember the set
               of branches that will be pushed out (e.g. if you always push
               maint and master there and no other branches, the repository
               you push to will have these two branches, and your local maint
               and master will be pushed there).

               To use this mode effectively, you have to make sure all the
               branches you would push out are ready to be pushed out before
               running git push, as the whole point of this mode is to allow
               you to push all of the branches in one go. If you usually
               finish work on only one branch and push out the result, while
               other branches are unfinished, this mode is not for you. Also
               this mode is not suitable for pushing into a shared central
               repository, as other people may add new branches there, or
               update the tip of existing branches outside your control.

               This used to be the default, but not since Git 2.0 (simple is
               the new default).

       push.followTags
           If set to true, enable --follow-tags option by default. You may
           override this configuration at time of push by specifying
           --no-follow-tags.

       push.gpgSign
           May be set to a boolean value, or the string if-asked. A true value
           causes all pushes to be GPG signed, as if --signed is passed to
           git-push(1). The string if-asked causes pushes to be signed if the
           server supports it, as if --signed=if-asked is passed to git push.
           A false value may override a value from a lower-priority config
           file. An explicit command-line flag always overrides this config
           option.

       push.pushOption
           When no --push-option=
