-
-b
-
Show blank SHA-1 for boundary commits. This can also
be controlled via the blame.blankBoundary config option.
-
--root
-
Do not treat root commits as boundaries. This can also be
controlled via the blame.showRoot config option.
-
--show-stats
-
Include additional statistics at the end of blame output.
-
-L <start>,<end>
-
-L :<funcname>
-
Annotate only the line range given by <start>,<end>,
or by the function name regex <funcname>.
May be specified multiple times. Overlapping ranges are allowed.
<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 forms:
-
number
If <start> or <end> is a number, it specifies an
absolute line number (lines count from 1).
-
/regex/
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)).
-
-l
-
Show long rev (Default: off).
-
-t
-
Show raw timestamp (Default: off).
-
-S <revs-file>
-
Use revisions from revs-file instead of calling git-rev-list(1).
-
--reverse <rev>..<rev>
-
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.
-
--first-parent
-
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 history overall.
-
-p
-
--porcelain
-
Show in a format designed for machine consumption.
-
--line-porcelain
-
Show the porcelain format, but output commit information for
each line, not just the first time a commit is referenced.
Implies --porcelain.
-
--incremental
-
Show the result incrementally in a format designed for
machine consumption.
-
--encoding=<encoding>
-
Specifies the encoding used to output author names
and commit summaries. Setting it to none makes blame
output unconverted data. For more information see the
discussion about encoding in the git-log(1)
manual page.
-
--contents <file>
-
Annotate using the contents from the named file, starting from <rev>
if it is specified, and HEAD otherwise. You may specify - to make
the command read from the standard input for the file contents.
-
--date <format>
-
Specifies the format used to output dates. If --date is not
provided, the value of the blame.date config variable is
used. If the blame.date config variable is also not set, the
iso format is used. For supported values, see the discussion
of the --date option at git-log(1).
-
--[no-]progress
-
Progress status is reported on the standard error stream
by default when it is attached to a terminal. This flag
enables progress reporting even if not attached to a
terminal. Can’t use --progress together with --porcelain
or --incremental.
-
-M[<num>]
-
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 algorithm 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 20.
-
-C[<num>]
-
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 commit.
<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-rev <rev>
-
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-revs-file <file>
-
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 files.
-
--color-lines
-
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 option.
-
--color-by-age
-
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.
-
-h
-
Show help message.
-
-c
-
Use the same output mode as git-annotate(1) (Default: off).
-
--score-debug
-
Include debugging information related to the movement of
lines between files (see -C) and lines moved within a
file (see -M). The first number listed is the score.
This is the number of alphanumeric characters detected
as having been moved between or within files. This must be above
a certain threshold for git blame to consider those lines
of code to have been moved.
-
-f
-
--show-name
-
Show the filename in the original commit. By default
the filename is shown if there is any line that came from a
file with a different name, due to rename detection.
-
-n
-
--show-number
-
Show the line number in the original commit (Default: off).
-
-s
-
Suppress the author name and timestamp from the output.
-
-e
-
--show-email
-
Show the author email instead of the author name (Default: off).
This can also be controlled via the blame.showEmail config
option.
-
-w
-
Ignore whitespace when comparing the parent’s version and
the child’s to find where the lines came from.
-
--abbrev=<n>
-
Instead of using the default 7+1 hexadecimal digits as the
abbreviated object name, use <m>+1 digits, where <m> is at
least <n> but ensures the commit object names are unique.
Note that 1 column
is used for a caret to mark the boundary commit.
