Find tag information for a given commit

Question

Is there a way to get the tag associated with a commit number in Git?

For releases I usually tag with something like v1.1.0. During my build script I am creating a fwVersion.c file that contains the current git info. Currently, I have commit, and branch info in the file, but I would like to add the tag.

Is this possible?

Thanks

Answer 1

RTFM my friend ;)

git tag --contains <commit>

Answer 2

Check the documentation for git describe. It finds the nearest tag to a given commit (that is a tag which points to an ancestor of the commit) and describes that commit in terms of the tag.

If you only want to know if the commit is pointed to by a tag then you can check the output of:

git describe --exact-match <commit-id>
