GIT-ANNOTATE(1)                                  Git Manual                                  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>
           Annotate only the given line range. <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 <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>.

       -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) gitlog(1)
           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>
           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 git-log(1).

       -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.
