As far as I can tell (lots of googling and some experimentation with the git command line), git submodule status always returns an exit code of 0.

What am I missing here? I'd like to see for myself a case where git submodule status returns a non-zero exit code. Is there an easy way to demonstrate it?

In other words, what's the easiest way to "corrupt" a submodule?

@jww3 This can be recreated by cloning https://github.com/test-SKi/test-bad-module-clone & using checkout action with any self-hosted runner to see the failure.

Steps to recreate one scenario:

git checkout -b new
git clone [email protected]:test-SKi/submodule-repo.git
echo "recreate bad submodule issue" >>  README.md
git add .
git commit
git push --set-upstream origin new

async tagExists(pattern: string): Promise<boolean> {
const output = await this.execGit(['tag', '--list', pattern])
return !!output.stdout.trim()
