git commit - How to fix committing to the wrong Git branch?

Question

I just made a perfectly good commit to the wrong branch. How do I undo the last commit in my master branch and then take those same changes and get them into my upgrade branch?

Answer 1

If you haven't yet pushed your changes, you can also do a soft reset:

git reset --soft HEAD^

This will revert the commit, but put the committed changes back into your index. Assuming the branches are relatively up-to-date with regard to each other, git will let you do a checkout into the other branch, whereupon you can simply commit:

git checkout branch
git commit -c ORIG_HEAD

The -c ORIG_HEAD part is useful to not type commit message again.
