CLI

CLI (Command-Line Interface) is a text-based interface that allows users to interact with computer systems by typing commands into a terminal or console. It provides direct access to operating system functions, applications, and tools through a series of text-based prompts and responses, enabling automation, scripting, and efficient system management.

Also known as: Command Line, Terminal, Shell, Console, Cmd

Why learn CLI?

Developers should learn CLI for tasks like server administration, file manipulation, version control (e.g., Git), and automation via scripting, as it offers greater control, speed, and flexibility compared to graphical interfaces. It is essential in DevOps, cloud computing, and backend development where remote server management and command-line tools are prevalent.
