Shell scripts are the most widely used, especially those written in bash-compatible languages. But these scenarios are often complex and unclear. Complexity is the enemy of security and the cause of unreadable code. Using practical examples, this book will show you how to decipher old scripts and write new code that is as clear and easy to read as possible. Authors Carl Albing and JP Vossen show you how to harness the power and flexibility of the shell. Even if you know how to write bash scripts, this book will help expand your knowledge and skills. Regardless of the OS you're using—Linux, Unix, Windows, or Mac—by the end of the book, you'll be able to understand and write expert-level scripts. This will definitely come in handy. You'll become familiar with idioms to use and ones to avoid.
