Some Git aliases I use constantly, with a rebase-heavy workflow:

    di = diff
    dc = diff --cached

    ap = add -p
    unstage = reset HEAD -p
    discard = checkout -p

    ci = commit -v
    ca = commit -va
    amend = commit -v --amend
    reword = commit -v --amend --only
    extend = commit -v --amend --no-edit

    ri = rebase -i
    rem = rebase master
    rim = rebase -i master
    red = rebase development
    rid = rebase -i development
    continue = rebase --continue
    skip = rebase --skip

    pu   = push -v --progress
    poof = push -v --progress --force-with-lease
    pusu = -c push.default=current push -v --progress --set-upstream
