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 such as file management, software installation, and system configuration through typed instructions. Unlike graphical user interfaces (GUIs), CLIs rely on precise command syntax and are often favored for automation, scripting, and remote server management.
Developers should learn CLI to efficiently perform system administration, automate repetitive tasks, and manage servers or cloud environments, as it offers greater control and speed for operations like file manipulation and process monitoring. It is essential for working with version control systems (e.g., Git), deploying applications, and using development tools that lack GUI support, making it a foundational skill for software engineering and DevOps roles.
