This is the Linux Phrasebook by Scott Granneman and I highly recommend it.
It is a very helpful 'how-to' when it comes to using the CLI for common
(and some not-so-common) tasks. Tasks such as file moving, file archiving,
setting file permissions, finding files and much much more.

I've been using Linux for quite a while, and I have (as of late) been
carrying it with me. It's lightweight, small, yet jam-packed with useful
information
that makes sense as soon as you read it, whether in front of a *nix box or not.
