It is for Linux administrators and users today looking for more and more practical examples along with more theoretical knowledge. This book will take readers through practical examples for clarity of each of the concepts by going through each line of the script. There are lots of examples that anyone can read and execute on their system and get to see the execution of scripts. You don’t have to be an expert. Most administrators are looking for more automation and run complex queries to save time and to increase productivity. Shell is the only way to get accomplished at this. This book will take administrators from the graphical interface to the command-line interface and explain the concepts of how things work on the operating system behind the graphics.
