UnixUnix[′yü·niks]Unix(operating system)The turning point in Unix's history came when it wasreimplemented almost entirely in C during 1972 - 1974, makingit the first source-portable OS. Unix subsequentlyunderwent mutations and expansions at the hands of manydifferent people, resulting in a uniquely flexible anddeveloper-friendly environment. By 1991, Unix had become the most widely used multi-usergeneral-purpose operating system in the world. Many peopleconsider this the most important victory yet of hackerdom overindustry opposition (but see Unix weenie and Unix conspiracy for an opposing point of view). Unix is now offered by many manufacturers and is the subjectof an international standardisation effort Unix-like operating systems include AIX, A/UX, BSD,Debian, FreeBSD, GNU, HP-UX, Linux, NetBSD,NEXTSTEP, OpenBSD, OPENSTEP, OSF, POSIX, RISCiX,Solaris, SunOS, System V, Ultrix, USG Unix, Version 7, Xenix. "Unix" or "UNIX"? Both seem roughly equally popular, perhapswith a historical bias toward the latter. "UNIX" is aregistered trademark of The Open Group, however, since it isa name and not an acronym, "Unix" has been adopted in thisdictionary except where a larger name includes it in uppercase. Since the OS is case-sensitive and exists in manydifferent versions, it is fitting that its name should reflectthis. The UNIX Reference Desk. Spanish fire extinguisher. UnixA multiuser, multitasking operating system that has been widely used in servers and high-end workstations. The Open Group holds the trademark for the UNIX name (spelled in upper case) on behalf of the industry and provides compliance certification to the UNIX standard (see Single UNIX Specification).Numerous commercial applications run on Unix servers; however, most websites run under Linux, which is a variant of Unix. Over the years, there have been many different Unix versions, and, except for the PC world, where Windows dominates, almost every hardware vendor has offered Unix either as its primary or secondary operating system. Sun was singularly instrumental in commercializing Unix with its Solaris OS (formerly SunOS), and HP, IBM, SCO and Digital Equipment (before it was acquired by Compaq) were also Unix promoters. From the Telephone Company Both Unix and the C programming language were developed by AT&T, dating back to the early 1970s. Unix and C were freely distributed to government and academic institutions, causing it to be ported to a wider variety of machine families than any other operating system. As a result, Unix became synonymous with "open systems" and thrives today on virtually every hardware platform. See AT&T. Command Lines and GUIs The Unix OS is made up of the kernel, file system and a shell, which is the command line interface with more than 600 commands for manipulating data and text. The major user interface shells are the original Bourne shell, C shell and Korn shell. Many commands are cryptic, but just as Windows hid the DOS prompt from users, graphical interfaces provide a Windows-like look into Unix and Linux. Linux desktops offer various GUIs, and many pundits claim that Apple created the best GUI for Unix with its OS X operating system, which is also Unix based. See Unix history, Mac OS X and Linux. Unix Is Everywhere Unix components are world class standards. The Internet runs on Unix protocols such as TCP/IP for network transfer and SMTP for email. NFS provides file sharing, Kerberos provides network security, and X Window lets users execute programs remotely in a mostly Unix environment. See POSIX, BSD Unix, USENIX and UDI. Versions of Unix that are compliant with The Open Group's UNIX specifications include Sun's Solaris, HP's HP-UX, IBM's AIX and z/OS and SCO's UnixWare. See Open Group, Solaris, HP-UX, AIX, z/OS, Mac OS X and Linux. In the following illustrations, notice how many workstations and servers have run and still run under Unix.
