Describe the state of the working tree. When the working

tree matches HEAD, the output is the same as "git describe

HEAD". If the working tree has local modification "-dirty"

is appended to it. If a repository is corrupt and Git

cannot determine if there is local modification, Git will

error out, unless ‘--broken’ is given, which appends

the suffix "-broken" instead.

Instead of using the default number of hexadecimal digits (which

a default of 7) of the abbreviated object name, use <n> digits, or

slightly longer but may produce a more accurate result.

Always output the long format (the tag, the number of commits
|
|
and the abbreviated commit name) even when it matches a tag.
|
|
This is useful when you want to see parts of the commit object name
|
|
in "describe" output, even when the commit in question happens to be
|
|
a tagged version. Instead of just emitting the tag name, it will
|
|
describe such a commit as v1.2-0-gdeadbee (0th commit since tag v1.2

<div class="paragraph"><p>The number of additional commits is the number

The hash suffix is "-g" + an unambiguous abbreviation for the tip commit

of parent (which was <code>2414721b194453f058079d897d13c4e377f92dc6</code>). The

length of the abbreviation scales as the repository grows, using the

|
approximate number of objects in the repository and a bit of math
|
|
around the birthday paradox, and defaults to a minimum of 7.
|
|
The "g" prefix stands for "git" and is used to allow describing the version of
|
|
a software depending on the SCM the software is managed with. This is useful

in an environment where people may use different SCMs.</p></div>

<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</code> <code>log</code> <code>tag</code><code>..</code><code>input</code>
|

will be the smallest number of commits possible.</p></div>
