I had not noticed that there was a new edition of "The Linux Command Line" until today.
If you use Linux, and perhaps especially if you are new to Linux, and want to get to grips with command line / terminal usage, it is well worth dipping into this free (CC BY-NC-ND) tome:
I am not telling anyone else how to Linux, but when I first started using it, I found this kind of thing invaluable.
I had, I think, a smaller book, "Linux Pocket Guide: Essential Commands" and that was so helpful too.
I am sure that one could use Linux without touching a terminal but, for me, the terminal is a fantastic and useful way of computing, and so upskilling in its usage has been time very well spent.
(See also books like "Practical vim" or "tmux in practice".)
@neil I bought a copy of "UNIX In A Nutshell (updated for System V R4!)" in the mid 90s and it's still my go-to reference for all things POSIX.
The spine is broken on the pages for grep, awk, sed, nroff and vi 😁
