The purpose of Command lines is to interface, navigate, and execute programs on a server or computer system. They enable users to input textual commands to configure files and folders effectively. Command lines essentially act as an intermediary between users and the computer’s operating system, allowing for precise and direct interaction with the system’s functions and processes. When a command is entered into the command line interface, it is passed on to the operating system to be executed, enabling users to perform a wide range of tasks and operations. This direct, text-based interaction with the computer system provides a powerful way to manage and control the system’s behavior and resources.
