Here's my favorite git oneliner:

  git push origin --delete $(git branch --merged origin/master -r | grep -v master | grep origin | cut -d/ -f2-)

It deletes all remote branches that are merged into the remote master. Because people always forget to click the "Delete branch" button after merging their pull requests.

EDIT: And another thing. Turn all your Git aliases into shell aliases (e.g. "git status" is aliased to "git st" is aliased to just "st" on my system) with this one weird trick! https://github.com/majewsky/devenv/blob/2c4252d37597617a493f...

While not an issue in Zsh, one bummer about using shell aliases in Bash is that auto-completion won't work. That doesn't really matter with an alias for `git status`, but it's annoying for plenty of others.

You can get around it doing the following:

    _completion_loader git  # manually load git completion functions

    alias g='git'
    __git_complete g _git

    alias ga='git add'
    __git_complete ga _git_add

For a more exhaustive list, see https://gist.github.com/brbsix/713feaf3034d60bbe4774cb8ee03b....

Why would you want to delete merged branches? i like to keep them. It's not costing you any storage.

Personally because it makes both `git branch -a` and tab-completing a branch virtually useless because there's just too many branches.

Exactly.

Is there a dry-run option for this?

Just run everything that's inside $(), which is this:

git branch --merged origin/master -r | grep -v master | grep origin | cut -d/ -f2-

Beautiful, I've been looking for something like this for a while. My only issue is getting a strange

  fatal: remote part of refspec is not a valid name in :MARKET-446

error which seems resistant to the usual sort of tweaks.

I'm getting errors such as: `error: unable to delete 'feature/cleanup-casts': remote ref does not exist`. But the branch does exist... Any ideas?

Fixed by fetching to prune first.
