git-describe(1) Manual Page
git-describe - Show the most recent tag that is reachable from a commit
git describe [--all] [--tags] [--contains] [--abbrev=<n>] <committish>...
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.
By default (without --all or --tags) git describe only shows annotated tags. For more information about creating annotated tags see the -a and -s options to git-tag(1).
Committish object names to describe.
Instead of using only the annotated tags, use any ref found in .git/refs/. This option enables matching any known branch, remote branch, or lightweight tag.
Instead of using only the annotated tags, use any tag found in .git/refs/tags. This option enables matching a lightweight (non-annotated) tag.
Instead of finding the tag that predates the commit, find the tag that comes after the commit, and thus contains it. Automatically implies --tags.
Instead of using the default 7 hexadecimal digits as the abbreviated object name, use <n> digits.
Instead of considering only the 10 most recent tags as candidates to describe the input committish consider up to <n> candidates. Increasing <n> above 10 will take slightly longer but may produce a more accurate result. An <n> of 0 will cause only exact matches to be output.
Only output exact matches (a tag directly references the supplied commit). This is a synonym for --candidates=0.
Verbosely display information about the searching strategy being employed to standard error. The tag name will still be printed to standard out.
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-deadbeef (0th commit since tag v1.2 that points at object deadbeef....).
- --match <pattern>
Only consider tags matching the given pattern (can be used to avoid leaking private tags made from the repository).
Show uniquely abbreviated commit object as fallback.
With something like git.git current tree, I get:
[torvalds@g5 git]$ git describe parent v1.0.4-14-g2414721
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, describe has added the number of additional commits ("14") and an abbreviated object name for the commit itself ("2414721") at the end.
The number of additional commits is the number of commits which would be displayed by "git log v1.0.4..parent". The hash suffix is "-g" + 7-char abbreviation for the tip commit of parent (which was 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/v1.0.0-21-g975b
[torvalds@g5 git]$ git describe --all HEAD^ heads/lt/describe-7-g975b
With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
[torvalds@g5 git]$ git describe --abbrev=0 v1.0.5^2 tags/v1.0.0
For each committish supplied, git-describe 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.
If an exact match was not found, git-describe 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 committish's SHA1.
If multiple tags were found during the walk then the tag which has the fewest commits different from the input committish will be selected and output. Here fewest commits different is defined as the number of commits which would be shown by git log tag..input will be the smallest number of commits possible.
