There's also "UNIX and Linux System Administration Handbook" (https://www.oreilly.com/library/view/unix-and-linux/97801342...)

For more such resources, I have a list here: https://learnbyexample.github.io/curated_resources/linux_cli...

I have also written CLI one-liner books for grep/sed/awk, currently free for Twosday: https://learnbyexample.gumroad.com/l/oneliners/Twosday

Evi Nemeth was Godmother to a couple generations of Unix Sysadmins. The UNIX and Linux System Administration Handbook is practical, usefully opinionated, playful, and brilliant, much like its lead author/editor. I've used it as the core text for classes I have taught and it's a great interview study guide for systems folk.

If you really want a trip down memory lane, dig up some earlier editions and learn how to deal with the quirks of the SGI, DEC, SUN, IBM, & HP menagerie.

I'd definitely start with this one.
