How to split last commit into two in Git

Question

I have two working branches, master and forum and I\'ve just made some modifications in forum branch, that I\'d like to ch

Answer 1

Goals:

• I want to split a past commit (splitme) into two.
• I want to maintain the commit message.

Plan:

1. rebase interactive from one before splitme.
2. edit splitme.
3. Reset the files to split into a second commit.
4. Amend commit, maintaining message, modify as necessary.
5. Add back the files split out from the first commit.
6. Commit with a new message.
7. Continue rebase.

The rebase steps (1 & 7) can be skipped if the splitme is the most recent commit.

git rebase -i splitme^
# mark splitme commit with 'e'
git reset HEAD^ -- $files
git commit --amend
git add $files
git commit -m "commit with just some files"
git rebase --continue

If I wanted the split files to be committed first, I'd then rebase -i again and switch the order

git rebase -i splitme^
# swap order of splitme and 'just some files'
