git remote update -p

@chrisng,
Actually, scratch what I said above RE: the delete script.
I tried to delete a remote branch without using push and it didn't work :-(

Furthermore, it has to be "push origin --delete" not just "push --delete" or there is an error saying that --delete can't be done for branch "origin/branch-name" because --delete doesn't work without a given ref.

For that reason I have to keep the cut command in there.

:D sounds good man!

Great script, very useful and safe. Only thing I noticed is that Bitbucket starts resetting the connection after ±20 requests. But you rerun the script after a half a minute for a couple of times, you can get through them all.

Glad you found the script useful @micros123. I had been using Gitlab when I originally needed this script. I'm using Bitbucket now. I wonder if there is something I can do about the timeout. I'll look into it. Thanks.

@micros123, not sure if you manage the bitbucket server yourself or not but if you have the access or know the team who would be able to change the setting. I think this is the documentation on how to address that:
