Code validation

Most programming languages uses some kind of standard. We can get help and support from the program shellcheck which is a static code validation tool and linter.

Using shellcheck is no more difficult than running a script:

$ shellcheck myscript.bash

#Installation

To install shellcheck directly in the terminal:

Debian
$ sudo apt-get install shellcheck

MacOS
$ brew install shellcheck

Windows
Unfortunately, there is no shellcheck in Cygwin, but if you use Powershell 3 (or later) you can install it through scoop: $ scoop install shellcheck

Atom
We can also install shellcheck as a plugin to linter in Atom.
