git-annotate(1)
NAME
git-annotate - Annotate file lines with commit information
SYNOPSIS
git annotate [options] file [revision]
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 given line range. 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.
-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
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.
-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>
When <rev> is not specified, the command annotates the changes
starting backwards from the working tree copy. This flag makes the
command pretend as if the working tree copy has the contents of the
named file (specify - to make the command read from the standard
input).
--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.
-h
Show help message.
