What is the correct way to run shell scripts in a hook in v9?

[janeklb]

In v8 etc we could put anything in the hook file

eg.

#!/bin/sh
. "$(dirname "$0")/_/husky.sh"

echo "Doing step 1 of pre-commit hook"
npx ....


echo "Doing step 2 of pre-commit hook"
npx ...

What's the correct way to achieve this in v9?

If i remove the shebang header and . "$(dirname "$0") ..., then the hooks fails because it doesn't understand echo "...". If I put the shebang back in then seems to work ok..

#!/bin/sh

echo "Doing step 1 of pre-commit hook"
npx ....


echo "Doing step 2 of pre-commit hook"
npx ...

However, if I remove the _ directory (rm -rf .husky/_) and run npm run prepare (initialising husky), then the _ is re-created. Should I be sourcing this directory in the hook script (as before), or is it purely optional now?
