Preface

Welcome to The Ultimate Linux Shell Scripting Guide! This book, which is ideal for both Linux beginners and more advanced Linux administrators, will guide you through the shell script creation process. We’ll begin with basic command-line usage and will progress through more advanced concepts in every succeeding chapter. You’ll see how to build scripts that can help you automate repetitive administrative tasks, as well as many other cool things. We’ll primarily concentrate on bash scripting throughout most of the book. Later, we’ll show you how to make your scripts portable so that they can run on legacy Unix systems that can’t run bash. After chapters on shell script debugging and shell script security, we’ll wrap up with introductions to the Z Shell and PowerShell.
