Linux is growing day by day, not only on servers but in desktop environments too. We designed this book for beginners to intermediate experts on shell scripting. 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. This book is written by someone who has had practical experience on scripting for over 20+ years. Upon completion, you will be able to write your own script by using basic to complex logic.

This book will cover all the areas that fall under scripting including:
• Usage of statements.
• You will learn what operators are and how to perform arithmetic operations.
• The power of loops and how to use loops in combinations to create magic within the system.
• What functions are and how to use them in different modes.
• How signals and traps can automate file management and other administrative tasks.
• A guide on how to debug your system with multiple options.

It explains every concept with practical examples. Users can keep this handbook as a quick reference guide to use as a future resource. You will be confident about how to create a new script and understand any script or change it to whatever script is needed, which is the core power of any system administrator.

So what are you waiting for? Now is the time to get started.
