What is Bourne?

The Bourne shell (sh) is a command-line interpreter for computer operating systems. It's one of the original Unix shells, developed by Stephen Bourne at Bell Labs. It's commonly used for scripting and executing commands in Unix-like environments. As the default shell for Unix Version 7, it introduced several features like control flow constructs, command substitution, and I/O redirection that are still prevalent in modern shells.
