You should really remove the entire PDF of the book that you've shared on a public repo. No Starch Press is a gem and worth protecting.
For anyone just starting I highly recommend: "Linux Pocket Guide" and if moving forward adopting linux as a daily driver "Efficient Linux At The Command Line". Both books by Daniel J. Barnett.
Even if you're a seasoned Linux user you will learn a lot from those books.
Based on the nearly decade old first edition of the book (2018). I was wondering about the retro vibes.
