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>, -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:

           o   number

               If <start> or <end> is a number, it specifies an absolute line
               number (lines count from 1).

           o   /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>.

           o   +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 <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.

       -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.

       --indent-heuristic, --no-indent-heuristic
           These are to help debugging and tuning experimental heuristics
           (which are off by default) that shift diff hunk boundaries to make
           patches easier to read.
