Aliases - I use daily these...

aliases.zsh

alias glog="git log --format='%Cgreen%h%Creset %C(cyan)%an%Creset - %s' --graph"
alias s="~/Sites/"
alias glean='git branch --merged master | grep -v "\* master" | xargs -n 1 git branch -d'
alias showFiles='defaults write com.apple.finder AppleShowAllFiles YES; killall Finder /System/Library/CoreServices/Finder.app'
alias hideFiles='defaults write com.apple.finder AppleShowAllFiles NO; killall Finder /System/Library/CoreServices/Finder.app'

I am thinking about adding this to the list. But I think it would be suitable with a input prompt

git for-each-ref --format="%(refname:short)" refs/heads/3.2\* | xargs git branch -D
