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!

You can use git filter-branch in --msg-filter mode.

Note that in any case, you'll rewrite the history hence change commit identifiers. If the history is already published, it's probably better to live with the typo than to try to fix it now.

I am aware of that, it is my local branch, so no worry.

Thanks.

This is exactly what I am looking for. Good to know this git command.

Thanks!

Both can be scripted, though.

I don't see the ugliness. There is no requirement that $EDITOR is interactive.
