Bourne Shell (sh)

The Bourne Shell (sh) is a command-line interface used in Unix and Linux systems. It allows users to execute commands, run scripts, and automate tasks by typing text instructions. Think of it as a way to communicate with the computer directly, telling it what to do. The Bourne Shell was one of the first widely used shells and provides fundamental features like scripting, input/output management, and program control structures. While more modern shells have additional capabilities, sh remains important for scripting compatibility and system maintenance tasks.
