Course Overview
Hi everyone. My name is Andrew Mallett, and welcome. Welcome to my course, Creating Shell Scripts in Enterprise Linux. I'm a Linux trainer and consultant working at The Urban Penguin within the UK, my own company. In this course, I've designed to get you automating the boring stuff in Linux by using scripts. As you work your way into this course, you will learn different elements of shell scripting and seeing how they can be used in a very practical way. Some of the major topics that we cover include using abbreviations within VIM, using prompts within a script when parameters haven't been supplied, checking into data using loops, and building menus for operators. By the end of this course, you will have more than enough knowledge to start building your own project scripts giving you much more time to attend to the important stuff. Before beginning this course, you should be familiar with Linux Server management and be able to install Linux systems. You're going to need a system to be able to work with. I hope you'll join me on this journey and you too will start enjoying automating the boring stuff.
