pure-bash-bible VS shellcheck-repl

I believe it's been posted here before, but I also use this for reference whenever I forget the syntax to something, or know there must be a better way than what I am doing.

I'd say check out the work of William Shotts at https://linuxcommand.org/ His book, "The Linux Command Line" is free for downloading, and there are lots of references to style guides, good practices, and bash templates in the book.

There is also a shorter, HTML version at the same site: https://linuxcommand.org/lc3_learning_the_shell.php

I'm trying to get a little proficiency in all this, and just yesterday I went through the "Further Reading" sections at the end of each chapter, and captured all the likely URLs for further investigation.

One that looks really good is Dylan Araps' "Pure Bash Bible" ( See https://github.com/dylanaraps/pure-bash-bible ) Confession: I found a PDF copy at Libgen, but don't tell anyone. This and the Shotts book have also been thoroughly discussed on Hacker News in the past. (I.e., search on the two titles and you'll probably get all the opinions that you can stand, plus maybe some more hints.)

Bash is profoundly weird, but if/when you can make it work, it's slick.

I recommend taking a look at https://github.com/dylanaraps/pure-bash-bible

Additionally, Pure Bash Bible is a bit more advanced but really fun to go through it.

Here is another resource I have found useful.

After falling in love with ShellCheck several years ago, with the help of another person, I made the ShellCheck REPL tool for Bash:

  https://github.com/HenrikBengtsson/shellcheck-repl>

Thank you, and thanks for the suggestion. Yes, it should be possible to keep the SC2154 check. I probably just disabled it as a quick fix when first started out. I'm tracking this in https://github.com/HenrikBengtsson/shellcheck-repl/issues/15.

> You'd also want to take into account special variables like $RANDOM and $HOSTNAME, but that's pretty trivial.

It seems like ShellCheck is already aware of these special Bash variable, e.g. 'echo $RANDOM' will not trigger SC2154 (or even SC2086 that otherwise asks you to quote variables).

shellcheck-repl: Validation of Shell Commands Before Evaluation

https://github.com/HenrikBengtsson/shellcheck-repl

This tool validates your commands at the Bash prompt using ShellCheck and refuses to evaluate them if there's a mistake. It ignores a set of rules that doesn't play well with oneliners.
