Re: Bash 5.0 released
#2Any recommended reading for Bash? I'm somewhat new to it and it's interesting ways of getting things done. I've used it minimally in the past, but have found myself writing a 100> LOC script, which I can't help but feel I'm likely over-complicating certain bits and pieces.

I've recently picked up a subscription to Destroy All Software and he has a few really good demos of how to architect simple and powerful shell scripts using bash. I'd really recommend it for anyone who doesn't need help with the semantics and instead needs help with the organization of a script.

The man pages for bash are fairly comprehensive and I'd definitely recommend referencing them while writing scripts: https://linux.die.net/man/1/bash

It can't be done. If you want to write reliable code, and actually notice all of the possible error conditions instead of silently ignoring them, your code needs to get more verbose and complicated than it would be to just use a more capable tool like Python or Node, and it still won't be as reliable.
If you have more logic than a couple of string comparisons, Bash is not the right tool for the job.

> have found myself writing a 100> LOC script
Often, this is a good sign that you might want to switch to another scripting language.

As they say, bash is just good enough not to get replaced.

Pardon my naivety, but what do you normally use?

The full manual is here. https://www.gnu.org/software/bash/manual/bashref.html
GNU projects tend have info pages that are a lot more complete and thorough then their man pages, so that'd be a good place to check too.

I recommend Greg's Wiki. It's the only resource I use. It covers common pitfalls and anti-patterns.
