Tag bash

I've recently been doing similar with some of my utilities, albeit with an informal comparison between Ruby and Go versions, but would agree that for large, production critical scrips, this is a great way to do it

I used to write a lot of shell scripts before realising that what I was trying to do was treat shell scripting as a "full" scripting language (I won't define here what I mean by "full").

Its not - reach for a higher level scripting language like Ruby or Python when things are getting more complicated, and allow shell scripts to glue things together, or be for quick tasks maybe a few lines long.

When you do write them, this advice is great but it's definitely worth gaining understanding of when you should and shouldn't use them.
