Command Line Interface
A Command Line Interface (CLI) is a text-based interface that allows users to interact with a computer system by typing commands into a terminal or console. It provides direct access to the operating system's functions, enabling tasks like file management, software installation, and system configuration through typed instructions. CLIs are widely used in development, system administration, and automation workflows due to their efficiency and scriptability.
Developers should learn CLI skills because they are essential for efficient system navigation, automation, and accessing advanced tools that lack graphical interfaces, such as version control systems (e.g., Git) and server management. It is particularly useful in DevOps, scripting repetitive tasks, and working in remote or headless environments like servers. Mastery of CLI improves productivity by enabling faster execution of commands compared to graphical user interfaces.
