Editing git changelog automatically

Hello, git experts

Sorry if this is a question already answered, but google search didn't give me anything useful.

My question is how to edit dozens of git commit changelogs automatically?

Let's say I want to fix a stupid typo in all of these commits, as simply as s/foo/bar/. Usually I use`git rebase -i` and `git commit --amend`, but both of them are interactive, apparently I don't want to edit them one by one. :)

I know I can change $EDITOR to something like `sed -e 's/foo/bar/'`, but this seems pretty ugly. Is there a clean way to do that?

Thanks!
