To my apprentices I always recommend this one: UNIX for Dummies.
It's written in a very funny way and gives you a good general overview, and yet you can learn a lot. There is a similar one: Linux for Dummies.
That one focusses more on Linux (and not so much on UNIX in general as the other one does), but it too is written in a very funny and entertaining way.
BTW, when in those books they mention a certain "Bill"
who invented things and that you should not dare to criticise those inventions (or "Bill" might get angry ...) .... They are talking of Bill Joy
from SUN Microsystems
... and not that certain other "Bill" from a certain company in Redmond ... (that "Bill" definitely never invented anything):
"... He was largely responsible for the authorship of Berkeley UNIX
, also known as BSD
, from which spring many modern forms of UNIX, including FreeBSD
, and OpenBSD
. Apple Computer has also based much of the Mac OS X
operating system line on BSD technology
. Some of his most notable contributions were TCP/IP, the vi editor, NFS, and the csh shell.
He rewrote BSD in one weekend, according to Nerds 2.0.1. ..."
So that's why. Someone who can rightfully claim to have invented TCP/IP, the "vi" editor and having been the key-person to create BSD UNIX is pretty much off-limits for criticism by us mortal beings. That would be blasphemy
