Show blank SHA-1 for boundary commits. This can also be
controlled via the blame.blankBoundary config option.
Do not treat root commits as boundaries. This can also be
controlled via the blame.showRoot config option.

. May be specified multiple times. Overlapping ranges
<start> and <end> are optional. -L
<start> or -L <start>, spans from
<start> to end of file. -L ,<end> spans from start
of file to <end>.
<start> and <end> can take one of these
If <start> or <end> is a number, it
specifies an absolute line number (lines count from 1).
This form will use the first line matching the given POSIX regex.
If <start> is a regex, it will search from the end of the
previous -L range, if any, otherwise from the start of file. If
<start> is ^/regex/, it will search from the start of
file. If <end> is a regex, it will search starting at the line
given by <start>.
•+offset or -offset
This is only valid for <end> and will specify a
number of lines before or after the line given by <start>.
If :<funcname> is given in place of
<start> and <end>, it is a regular expression that
denotes the range from the first funcname line that matches
<funcname>, up to the next funcname line.
:<funcname> searches from the end of the previous -L
range, if any, otherwise from the start of file. ^:<funcname>
searches from the start of file. The function names are determined in the
same way as git diff works out patch hunk headers (see Defining a
custom hunk-header in gitattributes(5)).
Show long rev (Default: off).
Show raw timestamp (Default: off).
Walk history forward instead of backward. Instead of
showing the revision in which a line appeared, this shows the last revision in
which a line has existed. This requires a range of revision like START..END
where the path to blame exists in START. git blame --reverse START is
taken as git blame --reverse START..HEAD for convenience.
Follow only the first parent commit upon seeing a merge
commit. This option can be used to determine when a line was introduced to a
particular integration branch, rather than when it was introduced to the

Detect moved or copied lines within a file. When a commit
moves or copies a block of lines (e.g. the original file has A and then B, and
the commit changes it to B and then A), the traditional blame
notices only half of the movement and typically blames the lines that were
moved up (i.e. B) to the parent and assigns blame to the lines that were moved
down (i.e. A) to the child commit. With this option, both groups of lines are
blamed on the parent by running extra passes of inspection.
<num> is optional but it is the lower bound on the number of
alphanumeric characters that Git must detect as moving/copying within a file
for it to associate those lines with the parent commit. The default value is
In addition to -M
, detect lines moved or copied
from other files that were modified in the same commit. This is useful when
you reorganize your program and move code around across files. When this
option is given twice, the command additionally looks for copies from other
files in the commit that creates the file. When this option is given three
times, the command additionally looks for copies from other files in any
<num> is optional but it is the lower bound on the number of
alphanumeric characters that Git must detect as moving/copying between files
for it to associate those lines with the parent commit. And the default
value is 40. If there are more than one -C options given, the
<num> argument of the last -C will take effect.
Ignore changes made by the revision when assigning blame,
as if the change never happened. Lines that were changed or added by an
ignored commit will be blamed on the previous commit that changed that line or
nearby lines. This option may be specified multiple times to ignore more than
one revision. If the blame.markIgnoredLines config option is set, then
lines that were changed by an ignored commit and attributed to another commit
will be marked with a ? in the blame output. If the
blame.markUnblamableLines config option is set, then those lines
touched by an ignored commit that we could not attribute to another revision
are marked with a *.
Ignore revisions listed in file, which must be in
the same format as an fsck.skipList. This option may be repeated, and
these files will be processed after any files specified with the
blame.ignoreRevsFile config option. An empty file name,
"", will clear the list of revs from previously processed
Color line annotations in the default format differently
if they come from the same commit as the preceding line. This makes it easier
to distinguish code blocks introduced by different commits. The color defaults
to cyan and can be adjusted using the color.blame.repeatedLines config
Color line annotations depending on the age of the line
in the default format. The color.blame.highlightRecent config option
controls what color is used for each range of age.
