Bourne shell

The UNIX Bourne shell (sh) was the first shell, named after its author, Steve Bourne of Bell Labs. The Bourne shell provides an easy-to-use language with which you can write shell scripts, although it does not have the interactive facilities provided by modern shells such as the C shell and Korn shell.
