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.
