Unix is now seen as a user-friendly, very secure, and robust operating system rather than the cold, command line-only operating system once thought to be useful only to computer experts.

Beginning Unix covers all basic aspects of the Unix operating system. What is unique about this book is that it covers not only the standard Unix systems, such as Sun's Solaris and IBM's AIX, but also Unix derivatives, such as Apple's Mac OS X and the various Linuxes. Additionally, this book includes a unique conversion section explaining how to convert Mac OS X–specific or Windows operating systems commands that you may already know into their Unix equivalents, making the transition ...
