'How to get the branch from tag name in Git?

I am trying to get the branch name from a given tag. I tried git describe --tag <tag-name> but this doesn't provide me any branch name. I tried using gitk to show to the tags and branch but gitk doesn't show me the tag. When I list out the tags git tag -l I see the tag name exist in the list.

I just want a simple command which can tell me the branch when tag name is provided.

A tag is just an alias name for a commit.

That said, this should answer your question: https://stackoverflow.com/a/2707110/550177

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/.*\///")
