@Michael_Harris, if you took your first steps in learning Linux back in 1994, this should be an easy walk for you now without a terminal.
I came to Windows in the 80s via the IBM PC and MS-DOS and didn’t look at Linux until Windows 8.1. I believed in a fiddling I could never do on my own. Mistake as it turns out today. It is made so easy today.
The standard work (The Linux Bible) by Kofler is now in its 17th edition 2021 and every IT student will be looking for the latest edition. I have the 14th edition from 2016 and notice in comparison that the basics never get lost. In the meantime, the basic work has grown to 1450 pages, taking into account the more current developments.
It is so pleasant not to have to read everything and slowly expand the knowledge according to topics. Mr. Kofler himself says he has sections that are still original as in the 1st edition. So you will read a part of your books like current and another part is described much too complicated by today’s standards.
