$ git branch -d branch_name
$ git branch -D branch_name

git push -d <remote_name> <branch_name>

$ git push -d origin <branch_name>

6. Squash my last X commits together using Git
   Use git rebase -i <after-this-commit> and replace “pick” on the second and subsequent commits with “squash” or “fixup”, as described in the manual.

git push <remote> <branch> --force
