Command Reference Book List

[Ferros]

I was wondering if anyone knows of a good book list for Command Reference titles for programming, networking, sys admin, and so forth. Not a bunch of HowTo books, but reference guides that people believe are invaluable to their library no matter what field they are interested in. Basically I'll i'm asking, what's on peoples' book shelves?

So your looking for reference books for everything regarding CLI?

Some more information might help ;)

I guess i should be a little more specific. For example, when it comes to Java, C#, c++, python, etc. what can people recommend as the best Command Reference books that anyone coding in any of these languages would have on their book shelves. CLI command reference would be good to. I'm looking more to start a conversation here rather than just get an "answer".
