Best way to sign (-S) each commit during an interactive rebase?

Question

If you are doing an interactive rebase (eg: git rebase -i HEAD~3) and you modify n-2 [aaaa]:

e aaaa commit message for n-2
pick bbbb commit message for n-1
pick cccc commit message for n

After you are done editing (git commit -S --amend), even if you used -S when you committed bbbb and cccc originally, they will no longer be verified because you modified a previous commit. Is there an easier way to sign bbbb and cccc instead of amending every commit in the chain like this:

e aaaa commit message for n-2
e bbbb commit message for n-1
e cccc commit message for n

and running

git commit -S --amend --no-edit && git rebase --continue for each commit?

With Git it's pretty much always a good idea to check for a config that sets it up to work the way you want.

Found by saying git help config and /commit.*sign:

git -c commit.gpgsign=true rebase

or just git config --global commit.gpgsign true.

[`git rebase --gpg-sign`](https://git-scm.com/docs/git-rebase#Documentation/git-rebase.txt--Sltkeyidgt). – phd Jul 26 '23 at 07:28
@phd I tried using -S [aka --gpg-sign] with -i and it wasn't working. – Nathaniel Jul 26 '23 at 17:33
@jthill Adding it to the config worked! Thank you!!! – Nathaniel Jul 26 '23 at 17:42

if `-S` doesn't work with `-i` I'd hazard that's not so much a bug as an exceptionally-difficult-to-overcome engineering limit. – jthill Jul 26 '23 at 21:11
