shellharden VS pure-bash-bible

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.

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.

Regarding linters, there are several of them in most languages.For bash, there is Shellcheck or a more strict (and sometimes confusing) Shellharden to do exactly what you want.

For example, shellharden looks awesome.

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.
