Unix history tree AT&T System V license plate UNIX System V Release 1 on SIMH (PDP-11). System V was the successor to 1982's UNIX System III.While AT&T developed and sold hardware that ran System V, most customers ran a version from a reseller, based on AT&T's reference implementation.
Unix (/ ˈ j uː n ɪ k s / ⓘ, YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 [1] at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. [4]
After the release of Version 10, the Unix research team at Bell Labs turned its focus to Plan 9 from Bell Labs, a distinct operating system that was first released to the public in 1993. All versions of BSD from its inception up to 4.3BSD-Reno are based on Research Unix, with versions starting with 4.4 BSD and Net/2 instead
Unix workstations of the 1990s, including those made by DEC, HP, SGI, and Sun The Common Desktop Environment (CDE) was widely used on Unix workstations. The Unix wars continued into the 1990s, but turned out to be less of a threat than originally thought: AT&T and Sun went their own ways after System V.4, while OSF/1's schedule slipped behind. [46]
The UNIX operating system originated as a development of MULTICS for a single user. [40] Because UNIX's source code was available, it became the basis of other, incompatible operating systems, of which the most successful were AT&T 's System V and the University of California 's Berkeley Software Distribution (BSD).

The filesystem appears as one rooted tree of directories. [1] Instead of addressing separate volumes such as disk partitions, removable media, and network shares as separate trees (as done in DOS and Windows: each drive has a drive letter that denotes the root of its file system tree), such volumes can be mounted on a directory, causing the volume's file system tree to appear as that directory ...
