Does anybody know of great guides to master the majority of the useful CLI tools available on Unix and Linux? For me the challenge is that I don't even know I have some of these fantastic solutions readily available. I'd really benefit of knowing they're there in the first place instead of hacking a homebrew solution every time.

Learn Linux the Hard Way talks about them quite a bit, is that the go to guide in 2012 or can I do better?

http://www.commandlinefu.com/commands/browse is a good resource to at least browse through for inspiration.

I also learned a lot from "The Linux Cookbook" (Second Edition) by Michael Stutz (this might be the first edition online: http://dsl.org/cookbook/cookbook_toc.html).
