Challenge

I have the SHA ID of a commit that I am interested in and would like to know how to find the first tag that contains it.

Solution

The commands show a reference to the commit built on a tag plus a ~$n ancestorhood count - they return the most recent tag that contains a commit. To remove the ancestorhood count pipe the result to sed:

<command> | sed 's/~.*//'

If there is no tag that contains this commit, git describe will fail.
