Splitting a Git commit into multiple commits

• Do an interactive rebase from an earlier commit.

• Change the command for the commit(s) to split to edit.

• When you run the rebase, you’ll be dropped back into the shell for each commit, at that commit.

• Reset to HEAD~1 to undo the commit

• git add -p to create the new commits

• Commit as normal

• git rebase --continue to go to the next commit to split, or finish.
