    Unix Unix Document Transcript

    • Unix-likeThe Unix-like family is a diverse group of operating systems, with several major subcategoriesincluding System V, BSD, and Linux. The name "Unix" is a trademark of The OpenGroup which licenses it for use to any operating system that has been shown to conform to thedefinitions that they have cooperatively developed. The name is commonly used to refer to thelargeset of operating systems which resemble the original Unix.Unix systems run on a wide variety of machine architectures. They are used heavily asserver systems in business, as well as workstations in academic and engineering environments.Freesoftware Unix variants, such as Linux and BSD, are increasingly popular. They are used inthedesktop market as well, for example Ubuntu, but mostly by hobbyists.Some Unix variants like HPs HP-UX and IBMs AIX are designed to run only on thatvendors proprietary hardware. Others, such as Solaris, can run on both proprietary hardwareand oncommodity x86 PCs. Apples Mac OS X, a microkernel BSD variant derived from NeXTSTEP,Mach, and FreeBSD, has replaced Apples earlier (non-Unix) Mac OS. Over the past severalyears,free Unix systems have supplanted proprietary ones in most instances. For instance, scientificmodeling and computer animation were once the province of SGIs IRIX. Today, they aredominated by Linux-based or Plan 9 clusters.The team at Bell Labs who designed and developed Unix went on to develop Plan 9 andInferno, which were designed for modern distributed environments. They had graphics built-in,unlike Unix counterparts that added it to the design later. Plan 9 did not become popularbecause,unlike many Unix distributions, it was not originally free. It has since been released underFreeSoftware and Open Source Lucent Public License, and has an expanding community ofdevelopers.Inferno was sold to Vita Nuova and has been released under a GPL/MIT license.
