Here are 5 books books I own and recommend for learning and understanding Linux 🎓🐧
👇Follow the thread 🧵
1. How Linux Works
This is what I recommend if you want to learn and understand the core functioning of Linux. How Linux Works is the perfect book if you are absolutely new or if you want to improve your Linux knowledge.
2. Linux Bible
This is perhaps the most comprehensive Linux book that covers a wide variety of topics. Running over 800 pages, you get everything from learning the basics of Linux command line to advanced sysadmin topics.
