Learning the shell.
Why do you need to learn the command line anyway? Well, let me tell you a story. Not long ago we had a problem where I used to work.

It also has a smaller learning curve than Perl does, and awk can be used almost everywhere in system monitoring scripts, where efficiency is key. This brief tutorial is designed to help you get started in awk programming.
