Ask HN: A Bash guide for Posix shell programmers?

It turns out the Bash manual groups the Bash specific features into its own chapter [1] and it's a short read and also there are not nearly as many Bash specific features as I thought.

The three most important resources I've used:
- https://tldp.org/LDP/abs/html/
- https://mywiki.wooledge.org/BashGuide
- https://www.shellcheck.net/ (can tell you if there's a Bash-specific replacement for a POSIX mechanic)
I'll be reading this book over the break: https://fabiensanglard.net/bash/

This may not explicitly meet your requirements, but I always find this site handy for quick reference:
https://learnxinyminutes.com/docs/bash/
It helpfully also links to the Bash manual:

Bash is slower. That's why a major Linux distribution would switch to NetBSD Almquist sh. On a Linux distribution, generally, bash is always found in the userland. But for scripting (non-interactive use), it's big and slow.
