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
