How to delete remotes/origin/{branch}?

Question

How do you delete a remotes/origin/{branch}?

Answer 1

use: git remote prune origin

or use git remote prune origin --dry-run to preview what branches will be removed.

As in git help remote

prune
Deletes all stale remote-tracking branches under . These stale branches have already been removed from the remote repository referenced by , but are still locally available in "remotes/".

With --dry-run option, report what branches will be pruned, but do not actually prune them.
