Switch off the branch that you want to delete. Most of the time, switching to master will allow you to delete a working branch:
$ git checkout master $ git branch -D mybranch
Delete the remote branch off GitHub:
$ git push origin --delete mybranch Enter passphrase for key '/home/vhu/.ssh/github/id_rsa': To git@github.com:whowutwut/xcat-doc.git - [deleted] mybranch
Verify branch is gone:
$ git branch -r origin/HEAD -> origin/master origin/large_cluster origin/master origin/sync upstream/master
There are times when you delete the branch off your local machine or from GitHub and it's become out of sync, you sync up the list, run the following:
git remote prune origin
