Unix (registrado oficialmente como UNIX es un sistema operativo portable, multitarea y multiusuario; desarrollado, en principio, en 1969, por un grupo de empleados de los laboratorios Bell de AT&T, entre los que figuran Ken Thompson, Dennis Ritchie y Douglas McIlroy.

Hasta 2009, el propietario de la marca UNIX fue The Open Group, un consorcio de normalización industrial. A partir de marzo de 2010 y tras una larga batalla legal, esta ha pasado nuevamente a ser propiedad de Novell, Inc. Solo los sistemas totalmente compatibles y que se encuentran certificados por la especificación Single UNIX Specification pueden ser denominados “UNIX” (otros reciben la denominación “similar a un sistema Unix” o “similar a Unix”). En ocasiones, suele usarse el término “Unix tradicional” para referirse a Unix o a un sistema operativo que cuenta con las características de UNIX Versión 7 o UNIX System V.

Unix (officially trademarked as UNIX, sometimes also written as Uɴɪx in small caps) is a multitasking, multi-user computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, Michael Lesk and Joe Ossanna.The Unix operating system was first developed in assembly language, but by 1973 had been almost entirely recoded in C, greatly facilitating its further development and porting to other hardware. Today’s Unix system evolution is split into various branches, developed over time by AT&T as well as various commercial vendors, universities (such as University of California, Berkeley’s BSD), and non-profit organizations.

The Open Group, an industry standards consortium, owns the UNIX trademark. Only systems fully compliant with and certified according to the Single UNIX Specification are qualified to use the trademark; others might be called Unix system-like or Unix-like, although the Open Group disapproves[2] of this term. However, the term Unix is often used informally to denote any operating system that closely resembles the trademarked system.

During the late 1970s and early 1980s, the influence of Unix in academic circles led to large-scale adoption of Unix (particularly of the BSD variant, originating from the University of California, Berkeley) by commercial startups, the most notable of which are Solaris, HP-UX, Sequent, and AIX, as well as Darwin, which forms the core set of components upon which Apple’s OS X, Apple TV, and iOS are based.[3][4] Today, in addition to certified Unix systems such as those already mentioned, Unix-like operating systems such as MINIX, Linux, and BSD descendants (FreeBSD, NetBSD, OpenBSD, and DragonFly BSD) are commonly encountered. The term traditional Unix may be used to describe an operating system that has the characteristics of either Version 7 Unix or UNIX System V.
