Command Line Interface (CLI)

A command-line interface (CLI) is a method of interacting with a computer program or operating system where the user issues commands to the program by typing in text commands. The user types in specific commands and parameters to perform specific tasks, and the program responds with output in the form of text. CLI is often used in a terminal or console window, and it is typically used by advanced users and system administrators to perform tasks more efficiently and quickly than using a graphical user interface (GUI).
