In this course, the viewer is taken on a journey from knowing little to nothing about shell scripts, all the way up to being able to implement usable scripts on a Linux system. At the very beginning of the course, fundamental concepts such as 'What is a script?' are answered, before moving on to create a very small and very simple script. Throughout the rest of the course, concepts such as variables, positional parameters, conditional statements, looping constructs, functions, and scheduling are explained and demonstrated. By the end of the course, the viewer will be familiar with all of the major concepts of shell scripts and be able to read, write, and troubleshoot simple shell scripts.
