Uniplus+ is a discontinued commercial version of the Unix System III and System V operating systems. It was available in the 1980s. It ran on the MC68000 Motorola chipset on Torch Triple X, among other machines.It was released by UniSoft.
troff is the major component of a document processing system developed by AT&T Corporation for the Unix operating system.
XENIX is a discontinued version of the UNIX operating system for various microcomputer platforms, licensed by Microsoft from AT&T Corporation in the late 1970s. The Santa Cruz Operation (SCO) later acquired exclusive rights to the software, and eventually replaced it with SCO UNIX.
ls is a command to list computer files in Unix and Unix-like operating systems.
ls is specified by POSIX and the Single UNIX Specification. When invoked without any arguments, ls lists the files in the current working directory. The command is also available in the EFI shell. In other environments, such as DOS, OS/2, and Microsoft Windows, similar functionality is provided by the
dir command. The numerical computing environments MATLAB and GNU Octave include an
ls function with similar functionality.
TYPSET was a document editor that was used with the 1964-released RUNOFF program, one of the earliest text formatting programs to see significant use.
This article presents a timeline of events in the history of computer operating systems from 1951 to the current day. For a narrative explaining the overall developments, see the History of operating systems.
Seventh Edition Unix, also called Version 7 Unix, Version 7 or just V7, was an important early release of the Unix operating system. V7, released in 1979, was the last Bell Laboratories release to see widespread distribution before the commercialization of Unix by AT&T Corporation in the early 1980s. V7 was originally developed for Digital Equipment Corporation's PDP-11 minicomputers and was later ported to other platforms.
UNIX System V is one of the first commercial versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as Unix System Unification, which solicited the collaboration of the major Unix vendors. It was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV.
UniSoft Corporation is an American software developer established in 1981, originally focused on the development of Unix ports for various computer architectures. Based in Millbrae, California, it now builds standardization and conformance testing applications for the digital television market.
exit is a command used in many operating system command-line shells and scripting languages.
The history of Unix dates back to the mid-1960s when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were jointly developing an experimental time sharing operating system called Multics for the GE-645 mainframe. Multics introduced many innovations, but had many problems.
more is a command to view the contents of a text file one screen at a time. It is available on Unix and Unix-like systems, DOS, Digital Research FlexOS, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows and ReactOS. Programs of this sort are called pagers.
more is a very basic pager, originally allowing only forward navigation through a file, though newer implementations do allow for limited backward movement.
The Model 7/32 and Model 8/32 were 32-bit minicomputers introduced by Perkin-Elmer after they acquired Interdata, Inc., in 1973. Interdata computers are primarily remembered for being the first 32-bit minicomputers. The 8/32 was a more powerful machine than the 7/32, with the notable feature of allowing user-programmable microcode to be employed.
Interactive Systems Corporation was a US-based software company and the first vendor of the Unix operating system outside AT&T, operating from Santa Monica, California. It was founded in 1977 by Peter G. Weiner, a RAND Corporation researcher who had previously founded the Yale University computer science department and had been the Ph. D. advisor to Brian Kernighan, one of Unix's developers at AT&T. Weiner was joined by Heinz Lycklama, also a veteran of AT&T and previously the author of a Version 6 Unix port to the LSI-11 computer.
as is a generic command name for an assembler on Unix.
Sun-1 was the first generation of UNIX computer workstations and servers produced by Sun Microsystems, launched in May 1982. These were based on a CPU board designed by Andy Bechtolsheim while he was a graduate student at Stanford University and funded by DARPA. The Sun-1 systems ran SunOS 0.9, a port of UniSoft's UniPlus V7 port of Seventh Edition UNIX to the Motorola 68000 microprocessor, with no window system. Early Sun-1 workstations and servers used the original Sun logo, a series of red "U"s laid out in a square, rather than the more familiar purple diamond shape used later.
The AT&T UNIX PC is a Unix desktop computer originally developed by Convergent Technologies, and marketed by AT&T in the mid- to late-1980s. The system was also known as PC-7300, and often dubbed the 3B1. Despite the latter name, the system had little in common with AT&T's line of 3B series computers. The system was tailored for use as a productivity tool in office environments and as an electronic communication center.
The Torch Triple X was a UNIX workstation computer produced by the British company Torch Computers, and launched in 1985. It was based on the Motorola 68010 microprocessor and ran a version of UNIX System V.
In computing, the
copy is a command in various operating systems. The command copies computer files from one directory to another.
Unix is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
