Git – How to delete a local branch or remote

Git – delete a local branch:

git branch -d some_example_local_branch

Git – delete/remove a remote branch:

git push origin : some_example_remote_branch

In case of error after trying to remove remote branch, run:

git fetch -p

This is what the error message would look like:

error: unable to push to unqualified destination: some_example_remote_branch
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to [email protected]_name'

and this is caused due to the fact that perhaps anyone else has already deleted the branch and you need to synchronize your branch list.
