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.
Schotts actually provides TLCL for free, and last updated it a month ago:

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.
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
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).
