How to delete a GIT branch

 Delete a Local Branch:

To delete the local branch, use one of the following:

git branch -d <branch_name>
git branch -D <branch_name>

• The -d option is an alias for --delete, which only deletes the branch if it has already been fully merged in its upstream branch.
• The -D option is an alias for --delete --force, which deletes the branch "irrespective of its merged status." [Source: man git-branch]

Delete Remote Branch

As of Git v1.7.0, you can delete a remote branch using

$ git push <remote_name> --delete <branch_name>
