Autosquashing in git rebase

A pretty nifty git trick, if you often interactively rebase your feature branches, is to set the rebase.autosquash option (i.e. git config --global rebase.autosquash true). By setting this option, or passing --autosquash to git rebase -i, you can have commits pre-marked as fixup or squash commits by putting “fixup!” or “squash!” in their commit message, followed by a prefix of the commit message of the commit you want it applied to.

So, given the following history:

01b7812 - (HEAD,feature) fixup! added
a0f1e7b - modified a
b88bf82 - added b, c and d
af0e25c - (master) initial commit

running git rebase -i master will present you with the following list:

pick b88bf82 added b, c and d
fixup 01b7812 fixup! added
pick a0f1e7b modified a

(Note that the “fixup” commit was moved to the right place.)
