I’ve also got the Linux Basics for Hackers book but it’s at home while I’m on vacation.
I’m just really happy rn yall :) this install took some work, SecureBoot kept getting in the way and I’m not the most savvy person so there was a lot of Googling and trial and error in the way of getting here.
Be mindful that Linux changes faster than a lot of books. I would stick to online documentation.
Those books were published in 2019 and 2021. They’ll still be mostly accurate a decade from now. Open-source developers usually try not to introduce breaking changes to mature software unless absolutely necessary.
Schotts actually provides TLCL for free, and last updated it a month ago:

Documentation is not the proper place for an absolute beginner to learn (unless it explicitly has tutorials, and even then they’re not always great).
Books will teach the essentials: my core UNIX knowledge comes from an SVR4 book I read in the late 2000s (a decade or more after it was relevant) and it’s still applicable today
