Love P., Merlino J., Zimmerman C. Beginning Unix

Wiley, 2005. — 480 p. — ISBN13: 978-0-7645-7994-3.The new millennium has seen many changes in many areas of computing, from new forms of storage with massive amounts of storage space, to systems that are far more powerful than the first computer users could have ever imagined. Designed and initially created more than 30 years ago, the Unix operating system has been part of the evolution of computers, so it’s no accident that Unix is still one of the most popular operating systems for mission-critical tasks. Unix is the basis for some of the most-used operating systems today, from Apple’s Mac OS X to Linux to the more commonly known Unix versions, such as Sun’s Solaris Unix and IBM’s AIX. Today many of the versions of Unix are available free to users and corporations, allowing for a larger use base than many had imagined when Unix was first being developed. 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.Unix Fundamentals
