The Thompson shell was the first Unix shell, introduced in the first version of Unix in 1971, and was written by Ken Thompson. [1] It was a simple command interpreter, not designed for scripting, but nonetheless introduced several innovative features to the command-line interface and led to the development of the later Unix shells.
Ken Thompson and Dennis Ritchie DEC PDP-7. In 1969, programmer Ken Thompson worked for Bell Labs on the Multics operating system on a GE 645 mainframe. During his work, Thompson developed Space Travel on the system. Multics was a collaborative project between several institutions for an interactive, multi-user operating system that provided ...
Kenneth Lane Thompson (born February 4, 1943) is an American pioneer of computer science.Thompson worked at Bell Labs for most of his career where he designed and implemented the original Unix operating system.
The ed text editor was one of the first three key elements of the Unix operating system—assembler, editor, and shell—developed by Ken Thompson in August 1969 on a PDP-7 at AT&T Bell Labs. [2] Many features of ed came from the qed text editor developed at Thompson's alma mater University of California, Berkeley. [4]
In 1969, Ken Thompson wrote the first UNIX system, then named Unics as a pun on Multics despite only using two design elements from Multics, [9] [10] in assembly language on a PDP-7, [11] as the operating system for Space Travel, a game which requires graphics to depict the motion of the planets.
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]
The Unix philosophy, originated by Ken Thompson, is a set of cultural norms and philosophical approaches to minimalist, modular software development. It is based on the experience of leading developers of the Unix operating system .
In 1971, Ken Thompson developed the Thompson shell in the first version of Unix. While simpler than the Multics shell, it contained some innovative features, which have been carried forward in modern shells, including the use of < and > for input and output redirection.
