How to delete remote branch (e.g. Github) from command line? [duplicate]

Question

I have a git repository in my local machine:
I add a new branch called test and add a few commits
Then I checkout to master branch and add commits to it.
So I use git push --all github and continue working on master. After some time I decide to completely remove the test branch and use: git branch -d test and git branch -r -d github/test, but it only deletes the local branch used for tracking the actual test branch as git says:

Deleted remote-tracking branch github/buggy (was acc5a58).

I'm asking if there's a way to actually remove the test branch from github servers from command-line?

Answer 1

Local Branch

git branch -D local_branch 

Remote Branch

git push origin --delete remote_branch 

Answer 2

As with every git server:

$ git push github :<BRANCH_NAME> 

or:

$ git push github --delete <BRANCH_NAME> 

Example:

$ git push github --delete test
