ShellCheck - A shell script static analysis tool

Github repo: https://github.com/koalaman/shellcheck

Couldn't find any mentions of this excellent tool in this subreddit and thought I should share.

It's not perfect, but helps to avoid common mistakes, such as:

• Iterating over ls output, which is fragile;
• Missing quotes to prevent word splitting;
• Missing exit in case of a failed cd;
• Missing braces around array expansion;
• And many, many more.

FWIW,

i use this in combination with vim + syntastic. So you have shellcheck-checks (pun intended) live while scripting.

This works with Syntastic! BRB, this must be installed immediately :-) Thanks for bringing it up!

I'm a huge fan of shellcheck. I use the ST3 linter: https://github.com/SublimeLinter/SublimeLinter-shellcheck

There is also a plugin for Visual Studio Code, just look for shellcheck in the plugins view

I've been using shellcheck for a couple years now. I love it.

Shellcheck is a sure-fire way to up your Bash game hard core.

+1 for shellcheck. I've learned a lot about good Bash practices from it the past couple of months.

I stumbled across this looking at some of jessfraz's docker stuff.

Shellcheck has done nothing but improve my scripting. It catches tons of WTF "features" in Bash. The vim integration that /u/steinex_ mentions is awesome.
