On March 6, 2003, the SCO Group ( formerly known as Caldera International and Caldera Systems ) filed a $ 1 billion lawsuit in the US against IBM for allegedly “ devaluing ” its version of the UNIX operating system.

On March 30, 2010, following a jury trial, Novell, and not The SCO Group, was " unanimously " to be the owner of the UNIX and UnixWare copyrights.

For example, in March 1999, Hardware Canada Computing donated a Horizon UltraSparc III UNIX Workstation valued at more than Cdn $ 8, 500.

DG / UX 1. 00, released in March, 1985, was based on UNIX System V Release 2 with additions from 4. 1BSD.

In 1996, the Santa Cruz Operation finally authorised the release of the twenty-year-old 6th Edition source code ( along with the source code of other versions of " Ancient UNIX "), and the full code plus the 1977 version of the commentary was published by Peer-To-Peer Communications ( ISBN 1-57398-013-7 ).

Later DEC computers, such as their VAX systems, were also popular platforms on which to run Unix ; the first port to VAX, UNIX / 32V, was finished in 1978 ( the VAX was only released in October 1977 ).

In June 1977, a lawyer from AT & T informed the group that they could not use the word UNIX as it was a trademark of Western Electric ( the manufacturing arm of AT & T until 1995 ), which led to the change of name to USENIX.

PWB / UNIX 1. 0, released July 1, 1977 was based on Version 6 Unix ; PWB 2. 0 was based on Version 7 Unix.

Also in New South Wales, a group at Wollongong University completed a port to the Interdata 7 / 32 in 1977 called Wollongong Interdata UNIX, Level 6, thus proving the portability of Unix and its new systems programming language C. A Bell Labs port to the Interdata 8 / 32 was not released.

In April 1999, Compaq announced that Tru64 UNIX 5. 0 successfully ran on Intel's IA-64 simulator.

With their purchase of Compaq in 2002, HP announced their intention to migrate many of Tru64 UNIX ′ s more innovative features ( including its AdvFS, TruCluster, and LSM ) to HP-UX.

Later, Sun and AT & T announced that the two firms would jointly develop AT & T's next version of UNIX: System V Release 4.

In May, the Common Open Software Environment ( COSE ) initiative was announced by the major players in the UNIX world from both the UI and OSF camps: Hewlett-Packard, IBM, Sun, Unix System Laboratories, and the Santa Cruz Operation.

Shortly after IBM announced plans for a native UNIX product, Stettner, having advocated a DEC UNIX product several times in the past, suggested to Bill Doll, a marketing manager, during a hallway conversation that it was finally time for DEC to make a native VAX Unix product available to its customers.

In 2007, IBM announced z / OS 1. 9 which includes several new USS features, including partial alignment with the newer Single UNIX Specification Version 3 ( UNIX 03 ).

On November 22, 2011 HP announced Project Odyssey-a project to redefine the future of mission-critical computing with a development roadmap that will unify UNIX ® and x86 server architectures on a single platform.

In 1988, AT & T announced its intent to buy up to a 20 % stake in Sun Microsystems, a company then most well known for making high-end UNIX workstations. Upset at their academic-minded supplier ( Bell Labs ) now turned competitor ( AT & T-CS ), the " Gang of Seven " founded the Open Software Foundation ( OSF ), each contributing source code from their UNIX SVR3 versions.

Microsoft announced on July 29, 1996 that it would develop a native version of IE for " Solaris and other popular variants of UNIX " to be available " by the end of 1996 " which would have " equivalent functionality as that provided in Microsoft Internet Explorer 3. 0 ", thus " delivering on its commitment to provide full-featured Web browser support on all major operating system platforms " as well as " supporting and promoting open standards, including HTML, ActiveX and Java ".

* The Art of Unix Usability, the book about programming and user interface philosophy in UNIX

It gained popularity with the publication of The UNIX Programming Environment by Brian W. Kernighan and Rob Pike — the first commercially published book that presented the shell as a programming language in a tutorial form.

As well as the Bourne shell, he wrote the debugger and The UNIX System, the second book on the UNIX system, intended for a general readership.

The book contains many contributions, quotations and comments from UNIX gurus past and present.

Given that the authors were the primary developers of the Unix operating system, it is natural that QED had a strong influence on the classic UNIX text editors ed, sed and their descendants such as ex and sam.

The Single UNIX Specification ( SUS ) is the collective name of a family of standards for computer operating systems to qualify for the name " Unix ".

* words ( Unix ), a standard file in UNIX

HP-UX ( Hewlett-Packard UniX ) is Hewlett-Packard's proprietary implementation of the Unix operating system, based on UNIX System V ( initially System III ) and first released in 1984.

In 1994, after AT & T had sold UNIX System V to Novell and the rival Unix International consortium had disbanded, the Open Software Foundation ceased funding of research and development of OSF / 1.

Lions ' Commentary on UNIX 6th Edition, with Source Code by John Lions ( 1976 ) contains the complete source code of the 6th Edition Unix kernel plus a commentary.

However, due to the 68010's small speed boost over the 68000 and its support for virtual memory it can be found in a number of smaller Unix systems, both with the 68451 MMU ( in the Torch Triple X ), and with a custom MMU ( such as the Sun-2 Workstation, AT & T UNIX PC, the NCR Tower XP and early HP9000s like the Model 300 and 310 ) and various research machines.

By the early 1990s, the major UNIX system vendors had begun to realize that the standards rivalries often termed as the Unix wars were causing all participants more harm than good, leaving the UNIX industry open to emerging competition from Microsoft.

OSF had previously merged with UNIX International in 1994, meaning that the new entity effectively represented all elements of the Unix community of the time.

Zilog also formed a Systems Division, which designed the Zilog System 8000, a Z8000-or Z80000-based multiuser computer system running a Unix derivative called ZEUS ( Zilog Enhanced UNIX System ).

The " 2900 " suffix was dropped at System Version 213 ( SV213 ) when ICL launched Series 39 in 1985 as the successor to the original 2900 series ; and the " Open " prefix was added after SV294 when VME became capable of hosting applications written originally for Unix through a UNIX System V Release 3 based subsystem using the ASCII character encoding adapted to run under VME.

Xenix was Microsoft's version of Unix intended for use on microcomputers ; because Microsoft was not able to license the " UNIX " name itself, they gave it an original name.

roff was the first Unix text-formatting computer program, the most important application run on the first machine specifically purchased to run UNIX, and a predecessor of the nroff and troff document processing systems.

NLUUG ( formerly known as The Netherlands Local Unix User Group ) is an association of professional UNIX / Linux users in the Netherlands.

There are now a number of dependency-tracking build utilities, but Make is one of the most widespread, primarily due to its inclusion in Unix, starting with the PWB / UNIX 1. 0, which featured a variety of tools targeting software development tasks.
