Completely new to Linux, never touched it a day in my life but I want to start learning. Recommendations for books and tools for practice?(r/linux4noobs)
The one single-best reference book on the topic of system administration is: UNIX and Linux System Administration Handbook.
The Linux Bible, How Linux Works, The Debian System, Slackware Linux Essentials, and CompTIA Linux+ all deserve places on the bookshelf.
