NAME
git-annotate - Annotate file lines with commit information
SYNOPSIS
git annotate [<options>] [<rev-opts>] [<rev>] [--] <file>
DESCRIPTION
Annotates each line in the given file with information from the
commit which introduced the line. Optionally annotates from a
given revision.
The only difference between this command and git-blame(1) is that
they use slightly different output formats, and this command
exists only for backward compatibility to support existing
scripts, and provide a more familiar command name for people
coming from other SCM systems.
OPTIONS
-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.
