Shell Script Best Practices, from a decade of scripting things
> "Use shellcheck."
(Disclaimer: I'm one of the authors)
After falling in love with ShellCheck several years ago, with the help of another person, I made the ShellCheck REPL tool for Bash:

Bash Pitfalls
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.

Shellcheck finds bugs in your shell scripts
Everytime I see Shellcheck coming up, I have to mention shellharden[0] written by a colleague of mine. It is basically shellcheck but it applies the suggested changes automatically.

Code formatter, linters, etc. Recommendations?
There is shellcheck, and shellharden which is a strict version of it. There are similar stuff here, some that also help with your editor. You can also use a docker version of shfmt. See here for a quick tutorial on shfmt.
