.SH "NAME"
git-annotate \- Annotate file lines with commit information
.SH "SYNOPSIS"
.sp
.nf
\fIgit annotate\fR [options] file [revision]
.fi
.sp
.SH "DESCRIPTION"
.sp
Annotates each line in the given file with information from the commit which introduced the line\&. Optionally annotates from a given revision\&.
.sp
The only difference between this command and \fBgit-blame\fR(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\&.
.SH "OPTIONS"
.PP
\-b
.RS 4
Show blank SHA\-1 for boundary commits\&. This can also be controlled via the
blame\&.blankboundary
config option\&.
.RE
.PP
\-\-root
.RS 4
Do not treat root commits as boundaries\&. This can also be controlled via the
blame\&.showroot
config option\&.
.RE
.PP
\-\-show\-stats
.RS 4
Include additional statistics at the end of blame output\&.
.RE
.PP
\-L <start>,<end>, \-L :<regex>
.RS 4
Annotate only the given line range\&. May be specified multiple times\&. Overlapping ranges are allowed\&.
.sp
<start> and <end> are optional\&. \(lq\-L <start>\(rq or \(lq\-L <start>,\(rq spans from <start> to end of file\&. \(lq\-L ,<end>\(rq spans from start of file to <end>\&.
.sp
<start> and <end> can take one of these forms:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
number
.sp
If <start> or <end> is a number, it specifies an absolute line number (lines count from 1)\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
/regex/
.sp
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 \(lq^/regex/\(rq, it will search from the start of file\&. If <end> is a regex, it will search starting at the line given by <start>\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
+offset or \-offset
.sp
This is only valid for <end> and will specify a number of lines before or after the line given by <start>\&.
.RE
.sp
If \(lq:<regex>\(rq is given in place of <start> and <end>, it denotes the range from the first funcname line that matches <regex>, up to the next funcname line\&. \(lq:<regex>\(rq searches from the end of the previous
\-L
range, if any, otherwise from the start of file\&. \(lq^:<regex>\(rq searches from the start of file\&.
.RE
.PP
\-l
.RS 4
Show long rev (Default: off)\&.
.RE
.PP
\-t
.RS 4
Show raw timestamp (Default: off)\&.
.RE
.PP
\-S <revs\-file>
.RS 4
Use revisions from revs\-file instead of calling
\fBgit-rev-list\fR(1)\&.
.RE
.PP
\-\-reverse
.RS 4
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\&.
.RE
.PP
\-p, \-\-porcelain
.RS 4
Show in a format designed for machine consumption\&.
.RE
.PP
\-\-line\-porcelain
.RS 4
Show the porcelain format, but output commit information for each line, not just the first time a commit is referenced\&. Implies \-\-porcelain\&.
.RE
.PP
\-\-incremental
.RS 4
Show the result incrementally in a format designed for machine consumption\&.
.RE
.PP
\-\-encoding=<encoding>
.RS 4
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
\fBgit-log\fR(1)
manual page\&.
.RE
.PP
\-\-contents <file>
.RS 4
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)\&.
.RE
.PP
\-\-date <format>
.RS 4
The value is one of the following alternatives: {relative,local,default,iso,rfc,short}\&. 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 more information, See the discussion of the \-\-date option at
\fBgit-log\fR(1)\&.
.RE
.PP
\-M|<num>|
.RS 4
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
\fIblame\fR
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\&.
.sp
<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\&.
.RE
.PP
\-C|<num>|
.RS 4
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\&.
.sp
<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\&.
.RE
.PP
\-h
.RS 4
