NAME
       fish - the friendly interactive shell

SYNOPSIS
       fish [OPTIONS] [FILE [ARG ...]]
       fish [OPTIONS] [-c COMMAND [ARG ...]]


DESCRIPTION
       fish is a command-line shell written mainly with interactive use in
       mind.  This page briefly describes the options for invoking fish.  The
       full manual is available in HTML by using the help command from inside
       fish, and in the fish-doc(1) man page.  The tutorial is available as
       HTML via help tutorial or in man fish-tutorial.

       The following options are available:

       -c or --command=COMMAND
              Evaluate the specified commands instead of reading from the
              commandline, passing additional positional arguments through
              $argv.

       -C or --init-command=COMMANDS
              Evaluate specified commands after reading the configuration but
              before executing command specified by -c or reading interactive
              input.

       -d or --debug=DEBUG_CATEGORIES
              Enables debug output and specify a pattern for matching debug
              categories.  See Debugging below for details.

       -o or --debug-output=DEBUG_FILE
              Specifies a file path to receive the debug output, including
              categories and  fish_trace.  The default is stderr.

       -i or --interactive
              The shell is interactive.

       -l or --login
              Act as if invoked as a login shell.

       -N or --no-config
              Do not read configuration files.

       -n or --no-execute
              Do not execute any commands, only perform syntax checking.

       -p or --profile=PROFILE_FILE
              when fish exits, output timing information on all executed
              commands to the specified file.  This excludes time spent
              starting up and reading the configuration.

       --profile-startup=PROFILE_FILE
              Will write timing for fish startup to specified file.

       -P or --private
              Enables private mode: fish will not access old or store new
              history.

       --print-rusage-self
              When fish exits, output stats from getrusage.

       --print-debug-categories
              Print all debug categories, and then exit.

       -v or --version
              Print version and exit.

       -f or --features=FEATURES
              Enables one or more comma-separated feature flags.

       The fish exit status is generally the exit status of the last
       foreground command.

DEBUGGING
       While fish provides extensive support for debugging fish scripts, it is
       also possible to debug and instrument its internals.  Debugging can be
       enabled by passing the --debug option.  For example, the following
       command turns on debugging for background IO thread events, in addition
       to the default categories, i.e. debug, error, warning, and
       warning-path:

          > fish --debug=iothread

       Available categories are listed by fish --print-debug-categories. The
       --debug option accepts a comma-separated list of categories, and
       supports glob syntax.  The following command turns on debugging for
       complete, history, history-file, and profile-history, as well as the
       default categories:

          > fish --debug='complete,*history*'

       Debug messages output to stderr by default. Note that if fish_trace is
       set, execution tracing also outputs to stderr by default. You can
       output to a file using the --debug-output option:

          > fish --debug='complete,*history*' --debug-output=/tmp/fish.log --init-command='set fish_trace on'

       These options can also be changed via the FISH_DEBUG and
       FISH_DEBUG_OUTPUT variables.  The categories enabled via --debug are
       added to the ones enabled by $FISH_DEBUG, so they can be disabled by
       prefixing them with - (reader-*,-ast* enables reader debugging and
       disables ast debugging).

       The file given in --debug-output takes precedence over the file in
       FISH_DEBUG_OUTPUT.
