I didn’t know a book could be this fun..
Format: Paperback
This book has been sooooo much fun since the second I opened it. Im a beginner at all of this. Just finished yesterday getting my first virtual machine up and running. Now I’m learning the different terminal commands. The book is literally a step by step guide. If you can follow instructions, and are brand new, this is a great book. Having ChatGPT open while I’m going through it has been very helpful. It’s nice to have a deeper understanding of certain things. I’m also not using windows or my primary OS and decided to learn Kali. I actually cannot wait to wake up in the morning and start working on chapter 3.

Great Linux Intro!
Format: Paperback
This is one of the best beginner Linux books out there, even if you’re not into hacking. OTW covers the essentials in a clear, practical way without boring fluff. Perfect for anyone looking to get hands-on with Linux, whether you’re breaking into cybersecurity or just want to stop being scared of the terminal.

This IS where you start to understand it all!
Format: Paperback
While I haven't received my Second Edition book yet I do have the First Edition and I can say it's very thorough and well explained to even the beginner level. If you're trying to learn both Linux and Cybersecurity this IS the place you want to start. It will save you a ton of headaches and you're getting VERY VALUABLE skills you can use in any scenario. I would call it an advanced starting point. Linux itself can be somewhat difficult and daunting to learn and understand if you're coming from a strict use (Windows in my case) OS 25+ years. This book bridges that gap effectively and you can absorb the knowledge with a little work. Also watching OTW's video on YouTube with David Bombal is an excellent follow along source. In my opinion, OTW does the best job of explaining exactly what you need to know. And follow it up with a video or two of how to understand the Linux file system and you'll soon be set to go. David Bombal's vids on setting up VM on your computer are also very helpful! If your intention is to get into Cybersecurity from zero knowledge this IS the best point to gain valuable knowledge whether it's to crack into IT, Cybersecurity or just for your own knowledge, this book is worth 10x it's price!
