Bourne shell

The Bourne shell is a command-line interface used in Unix and Linux operating systems, allowing users to interact with the computer by typing text-based commands. It functions as a program that interprets and executes these commands, enabling tasks like file management, running programs, and scripting automated processes. Developed in the 1970s, it laid the foundation for many later shells and remains integral for system administrators and developers to automate and control system operations efficiently.
