Remove old remote branches from Git
When I use bash autocompletion in Git, it keeps showing me branches of old remotes that I don't have anymore. When I do a git branch -la it shows those old remotes and branches while a git branch -l won't. A ls .git/refs/remotes/ also shows them. However, they are not present in my .git/config and neither are they shown when I run git remote show .
So how do I get rid of them because my autocomplete list is too long right now.
I have already tried:
git reflog expire --expire=now --all
git gc --prune=now
rm .git/refs/remotes/theoldremote
git remote prune theoldremote
I'm also aware of the fact that I can just re-clone the repo but that's just cheating ;-)
Git does not delete the (local) remote-tracking branches automatically if the branch was deleted in the remote repository. Additionally, before V2.0.1 remote-tracking branches were in some cases not deleted when you removed the remote from your git config (see VonC's answer).
To delete stale remote-tracking branches (branches that were deleted in the remote repository) for one of your remote repositories, run
git remote prune <remote>
To cite the man page or git remote :
prune
Deletes all stale tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in "remotes/<name>".
With --dry-run option, report what branches will be pruned, but do not actually prune them.
However, from your question it seems you manually removed .git/refs/remotes/theoldremote , so Git no longer knows about the remote repository that the remote-tracking branches belonged to. That's not how you're supposed to do it.
The normal way to remove a remote repository is to run
git remote rm <remote>
This will remove the remote from your .git/config , and will delete the remote-tracking branches.
If you just delete the directory under .git/refs/remotes/ , the branches will remain behind. Then you will need to remove them manually:
git branch -rd <remote>/<branchname>
You need option -r to delete a remote branch.
I use
git push origin :remote_branch
to remove a branch from server.
git remote prune origin
to remove remote references which are not exists on server anymore
Note: while git remote prune is the answer, know that, starting with git 2.0.1 (June 25th, 2014), a git remote rm starts by removing the remote tracking branches .
So hopefully, one shouldn't have to cleanup old branches after a git remote rm .
See commit b07bdd3 by Jens Lindström ( jensl )
remote rm : delete remote configuration as the last
When removing a remote, delete the remote-tracking branches before deleting the remote configuration.
This way, if the operation fails or is aborted while deleting the remote-tracking branches, the command can be rerun to complete the operation .
