SYNOPSIS
|
|
|
|
|
--------
|
|
|

DESCRIPTION
|
|
|
|
|
-----------
|
|
|
|
|
The command finds the most recent tag that is reachable from a
|
|
|
|
|
commit, and if the commit itself is pointed at by the tag, shows
|
|
|
|
|
the tag. Otherwise, it suffixes the tag name with abbreviated
|
|
|
|
|
object name of the commit.
|
|
|

|
|
OPTIONS
|
|
|
|
|
-------
|
|
|
|
|
<committish>::
|
|
|
|
|
The object name of the comittish.
|
|
|
|
|
|
|
|
|
|
--all::
|
|
|
|
|
Instead of using only the annotated tags, use any ref
|
|
|
|
|
found in `.git/refs/`.
|
|
|
|
|
|
|
|
|
|
--tags::
|
|
|
|
|
Instead of using only the annotated tags, use any tag
|
|
|
|
|
found in `.git/refs/tags`.
|
|
|
|
|
|
|
|
|
|
--abbrev=<n>::
|
|
|
|
|
Instead of using the default 8 hexadecimal digits as the
|
|
|
|
|
abbreviated object name, use <n> digits.
|

EXAMPLES
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
With something like git.git current tree, I get:
|
|
|
|
|
|
|
|
|
|
[torvalds@g5 git]$ git-describe parent
|
|
|
|
|
v1.0.4-g2414721b
|
|
|
|
|
|
|
|
|
|
i.e. the current head of my "parent" branch is based on v1.0.4,
|
|
|
|
|
but since it has a few commits on top of that, it has added the
|
|
|
|
|
git hash of the thing to the end: "-g" + 8-char shorthand for
|
|
|
|
|
the commit `2414721b194453f058079d897d13c4e377f92dc6`.
|
|
|
|
|
|
|
|
|
|
Doing a "git-describe" on a tag-name will just show the tag name:
|
|
|
|
|
|
|
|
|
|
[torvalds@g5 git]$ git-describe v1.0.4
|
|
|
|
|
v1.0.4
|
|
|
|
|
|
|
|
|
|
With --all, the command can use branch heads as references, so
|
|
|
|
|
the output shows the reference path as well:
|
|
|
|
|
|
|
|
|
|
[torvalds@g5 git]$ git describe --all --abbrev=4 v1.0.5^2
|
|
|
|
|
tags/v1.0.0-g975b
|
|
|
|
|
|
|
|
|
|
[torvalds@g5 git]$ git describe --all HEAD^
|
|
|
|
|
heads/lt/describe-g975b
|
