What is one key function of the command line interface (CLI)?

The command line interface (CLI) serves a vital role in allowing users to interact with the operating system by typing text commands. This method enables the execution of tasks in a direct and efficient manner, offering a powerful alternative to graphical interfaces. Users can perform a variety of functions such as launching applications, managing files, and configuring system settings all through text-based commands.

The CLI is particularly valued for its speed and flexibility, as skilled users can quickly execute complex tasks that may require multiple clicks in a graphical user interface (GUI). Additionally, the CLI often supports scripting, allowing users to automate repetitive tasks, which enhances productivity.

This functionality sets the command line interface apart from other methods of interaction with a computer system, such as managing files graphically, handling hardware at a low level, or simply displaying notifications to users. Each of these aspects plays a role in operating systems, but they do not embody the core purpose of the CLI, which is centered around executing commands through text input.
