I'm looking for good resources for learning POSIX compliant shell scripting. So far I have found not much that hasn't been written with AI or just isn't very in depth. I can easily find specific stuff, but I'd love a general guide of some sort.

I found one that seemed like it would be fantastic, then found out it was made using Claude.

I haven't done a lot of sh in a while, and my partner wants to learn, so it would be great to have some quality resources.

Thank you to anyone who can help me out.

Edit: bash stuff is good too, but I prefer to avoid bashisms when possible
