git-name-rev(1) Git Manual 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
