A Begginer’s guide to shell scripting

Shell scripts are one of the easiest programming languages to learn. They are a Linux administrators best friend and you can use them to automate tasks like a server backup or even just to email you the IP address of your Raspberry Pi server on boot.

In this post we will see how to write a simple shell script and then proceed to some intermediate shell scripting examples.

Before we start, I recommend you install “VIM”, a file editor, via yum .

Let’s get started with a simple script to tell us the disk usage in the current directory
