Interactive Unix Shell

An Interactive Unix Shell is a command-line interface that allows users to communicate with the Unix operating system directly. It accepts commands entered by the user and executes them immediately, providing real-time feedback or results. Think of it as a conversation between the user and the computer’s core system, enabling tasks like file management, program execution, and system control through typed instructions. It’s called "interactive" because it responds instantly to each command, offering a flexible and efficient way for users and administrators to manage and configure Unix systems.
