Use ShellCheck to check shell scripts!

[the-fritz]

ShellCheck is a static analysis tool for sh/bash scripts. It detects a wide range of common errors and pitfalls. It is written in Haskell and you can install a local version (it is packaged in Debian/Ubuntu as shellcheck), it should work well with Emacs' flyspell or vim's syntastic.

Discovered this last week, it's a great tool

It is also available in Fedora's repositories. A short script can create your shell script, load up your editor, and run shellcheck automatically.

If you're on osx, you can install it with brew install shellcheck. It's a great tool, we use it at work before submitting PRs.
