If you hope to outmaneuver threat actors, speed and efficiency need to be key components of your cybersecurity operations. Mastery of the standard command-line interface (CLI) is an invaluable skill in times of crisis because no other software application can match the CLI’s availability, flexibility, and agility. This practical guide shows you how to use the CLI with the bash shell to perform tasks such as data collection and analysis, intrusion detection, reverse engineering, and administration.
Authors Paul Troncone, founder of Digadel Corporation, and Carl Albing, coauthor of bash Cookbook (O’Reilly), provide insight into command-line tools and techniques to help defensive operators collect data, analyze logs, and monitor networks. Penetration testers will learn how to leverage the enormous amount of functionality built into nearly every version of Linux to enable offensive operations.

Don't get me wrong, there were some neat bash scripts and tricks in this book. But I felt like the book focused too much on bash and related tools, and too little on actual "cybersecurity ops". That is, it was spread too thin on its goals. I would have rather liked to see a larger focus on techniques, and theory, with anecdotes on how to accomplish them in bash. Lastly, much of the scripts felt too cumbersome to do in bash, and would have been better suited to non-shell languages or dedicated well-known programs.
Its useless book with easy bash commands. If you a good specialist, you already have been knew all commands and how to work with us. I might recommend this book for only beginners.
