Tags and Branches in Git are only Labels pointing to specific snapshot of your files. That being said, Tags ain't linked to a branch, but to a commit.

As so, you have to check wich branch contain the commit pointed by your tag, as so:

git branch --contains <tag name>

Answer 2

If you know the commit number the tag is linked to, you can find the branch from which the tag was placed from this command:

git_branch=$(git for-each-ref | grep ${commit_num} | grep origin | sed "s/.*\///")
