<p>The command finds the most recent tag that is reachable from a
|
|
commit. If the tag points to the commit, then only the tag is
|
|
shown. Otherwise, it suffixes the tag name with the number of
|
|
additional commits on top of the tagged object and the
|
|
abbreviated object name of the most recent commit. The result
|
|
is a "human-readable" object name which can also be used to
|
|
identify the commit to other git commands.</p>

|
<p>By default (without --all or --tags) <code>git describe</code> only shows

annotated tags. For more information about creating annotated tags

as <code><commit-ish>:<path></code>, such that the blob can be found

at <code><path></code> in the <code><commit-ish></code>, which itself describes the
|
|
first commit in which this blob occurs in a reverse revision walk
|

<div class="sectionbody">

<div class="paragraph">
|
|
<p>For each commit-ish supplied, <em>git describe</em> will first look for
|
|
a tag which tags exactly that commit. Annotated tags will always
|
|
be preferred over lightweight tags, and tags with newer dates will
|
|
always be preferred over tags with older dates. If an exact match
|
|
is found, its name will be output and searching will stop.</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>If an exact match was not found, <em>git describe</em> will walk back
|
|
through the commit history to locate an ancestor commit which
|
|
has been tagged. The ancestor’s tag will be output along with an
|
|
abbreviation of the input commit-ish’s SHA-1. If <code>--first-parent</code> was
|
|
specified then the walk will only consider the first parent of each
|
|
commit.</p>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>If multiple tags were found during the walk then the tag which
|
|
has the fewest commits different from the input commit-ish will be
|
|
selected and output. Here fewest commits different is defined as
|
|
the number of commits which would be shown by <code>git log tag..input</code>
|
|
will be the smallest number of commits possible.</p>
