Nothing esoteric, but I advise every person I teach git about to put this in their .bashrc:

    alias s='git status'
    alias l='git log --graph --oneline --decorate --all --show-signature'
    alias d='git diff'
    alias dc='git diff --cached'
    alias c='git commit -m'
    alias ca='git commit -am'
    alias a='git add -p'
    alias u='git checkout -p'

These probably saved me hours of typing by now. Especially `l` I think should be canon.
