What type of operating system uses a command line interface (CLI)?

An operating system that uses a command line interface (CLI) allows users to interact with the system by typing commands into a console or terminal. While many desktop operating systems do offer graphical user interfaces (GUIs), they also typically support a command line interface for advanced users who prefer or require more control and precision over their tasks. This CLI allows users to execute scripts, automate processes, and perform batch operations more efficiently than they might be able to do using a GUI.

Among the other types of operating systems, server operating systems can also use a command line interface, but the primary association with CLI in the context of general usage often points towards desktop OS offerings, as they are widely used in both personal and professional settings where CLI is frequently employed for troubleshooting, programming, and system administration. Mobile operating systems are designed primarily for touch-based interactions, which inherently limit the use of CLI, and real-time operating systems focus on time constraints rather than user interaction styles, where CLI might be less relevant or common. Thus, the connection to CLI with a desktop operating system holds strong in various contexts.
