git-name-rev(1)


NAME

   git-name-rev - Find symbolic names for given revs

SYNOPSIS

   git name-rev [--tags] [--refs=<pattern>]
                  ( --all | --stdin | <commit-ish>... )

DESCRIPTION

   Finds symbolic names suitable for human digestion for revisions given
   in any format parsable by git rev-parse.

OPTIONS

   --tags
       Do not use branch names, but only tags to name the commits

   --refs=<pattern>
       Only use refs whose names match a given shell pattern. The pattern
       can be one of branch name, tag name or fully qualified ref name.

   --all
       List all commits reachable from all refs

   --stdin
       Transform stdin by substituting all the 40-character SHA-1 hexes
       (say $hex) with "$hex ($rev_name)". When used with --name-only,
       substitute with "$rev_name", omitting $hex altogether. Intended for
       the scripter's use.

   --name-only
       Instead of printing both the SHA-1 and the name, print only the
       name. If given with --tags the usual tag prefix of "tags/" is also
       omitted from the name, matching the output of git-describe more
       closely.

   --no-undefined
       Die with error code != 0 when a reference is undefined, instead of
       printing undefined.

   --always
       Show uniquely abbreviated commit object as fallback.

EXAMPLE

   Given a commit, find out where it is relative to the local refs. Say
   somebody wrote you about that fantastic commit
   33db5f4d9027a10e477ccf054b2c1ab94f74c85a. Of course, you look into the
   commit, but that only tells you what happened, but not the context.

   Enter git name-rev:

       % git name-rev 33db5f4d9027a10e477ccf054b2c1ab94f74c85a
       33db5f4d9027a10e477ccf054b2c1ab94f74c85a tags/v0.99~940

   Now you are wiser, because you know that it happened 940 revisions
   before v0.99.

   Another nice thing you can do is:

       % git log | git name-rev --stdin
