Break a previous commit into multiple commits

Question

Without creating a branch and doing a bunch of funky work on a new branch, is it possible to break a single commit into a few different commits after it\'s been committed to

Answer 1

A quick reference of the necessary commands, because I basically know what to do but always forget the right syntax:

git rebase -i 
# mark the targeted commit with 'edit'
git reset HEAD^
git add ...
git commit -m "First part"
git add ...
git commit -m "Second part"
git rebase --continue
