# Git rebase is a weird 3-way thing that compares local commits to upstream commits.
# Yes really. So if you just want to edit some local commits, you need an upstream
# branch with exactly the same commits on it, to avoid git doing weird stuff.
# There doesn't seem to be any "local only" option in git rebase.
git config user.name 'Full Name'
git config user.email '[email protected]'
git branch temp-1
# this is the critical step:
git push -u origin temp-1
# git rebase -i --root --exec "git commit --amend --reset-author --no-edit"
