Is there a specific hook that is executed on git submodule update?

I'd like to ask if there is a possible way that a hook is executed on git submodule update; possibly like a post-update hook? thanks! :)

I like to execute a script (for now it just contains echo msg) that is executed every time git submodule update is run.

I have tried post-update hook but it seems that submodule update does not trigger this. I'd appreciate help. thank you very much!

Create an alias:

git config alias.sup !"git submodule update; my-post-sup-hook"

and always update submodules using the alias:

git sup

A post-update, like a post-receive hook, would be a server-side hook.
So it is expected to not work locally (client side)

So there is no specific hook for a git submodule update, which means you would need to script the git command itself in a wrapper, to detect the submodule argument, and chain that command with your echos.

Another convoluted approach is described in "git-submodule with git-hooks — A way to scalable repositories" from Ashwini Kumar, where a pre-commit hook is trigger by a git commit (done after a git submodule update), which will look at the diff introduced by said commit.
If the diff involves submodules, then it proceeds with additional commands.
