git cleanup

.gitconfig

# This alias lets you use "git cleanup" in the following scenario:
#   - you're on a branch
#   - that branch just got merged on the remote
#   - you would like to switch to master, update it, and delete your now-useless local branch
#   - you don't want to type three almost-identical commands every time you do this thing you do all the time
# Yay! Now you can do the thing in two words.
[alias]
        cleanup = "!f() { branch_name=$(git rev-parse --abbrev-ref HEAD); git checkout master; git branch -D ${branch_name}; git pull;}; f"

I love this one. Thanks for sharing.

Yay, I'm glad it works for you!

Also useful for me:
derpsquish = "!git add . && git commit -a --amend -C HEAD"

(This is for when you committed some stuff, then made a couple of changes that you immediately thereafter thought of which belonged in that commit. It replaces git commit -am"Earlier commit message", git commit -am"derp", then squashing the commits.)
