Command Line Interface

A Command Line Interface (CLI) is a text-based interface that allows users to interact with a computer’s operating system or software applications by typing commands into a terminal or console. Unlike a Graphical User Interface (GUI), which uses visual elements like icons and menus to interact with an application, a CLI requires users to enter commands manually.

CLI commands are typically made up of a command name followed by one or more arguments or options. These commands can perform a wide range of functions, from simple file management tasks like creating, copying, and deleting files, to more complex tasks like configuring network settings or running system diagnostics.

While it may seem intimidating to use a CLI at first, it can be a powerful tool for developers and system administrators who need to perform repetitive or complex tasks quickly and efficiently. CLI commands can be scripted, meaning that a series of commands can be saved and executed automatically, saving time and reducing the risk of errors.

Some popular CLI interfaces include the Windows Command Prompt, Unix and Linux terminals, and the macOS Terminal. Many 프로그래밍 언어 also include their own CLI interfaces for running 코드 and managing dependencies.

Overall, the command line interface offers a flexible and efficient way to interact with computer systems and applications, making it an essential tool for developers and power users alike.
