This is a question that often comes up in a team environment when using Git.
I'm trying to remove a branch both locally and remotely on my fork...
How do I delete this branch both locally and on Github?...
Deleting a remote branch:
git push origin --delete <BRANCH_NAME>
Note that origin could be changed to upstream if you're trying to remove the branch from the upstream (original) repository of your fork.
Deleting Local Branches:
git branch -d <BRANCH_NAME>
-D instead of
-d forces the delete, where
-d will warn you if the branch hasn't been merged.
