But there's much more here. There are chapters devoted to topics like the different UNIX "shells" (and their descriptions), file manipulation (along with opening, editing, saving, and printing files), working with the X Windows system, UNIX text editors like vi and emacs, and even how UNIX and the 'Net are intertwined with each other.
One more thing I liked about this book (besides the wonderful diagrams and screen captures) was the attention paid to describing various UNIX commands and their options. That really helps to "de-mystify" this operating system.
Even though I'm more of an "intermediate" UNIX user, I've searched for a long time for a good introductory UNIX book. I'd say this one definitely fits the bill.
