The user types commands and receives text-based feedback or results from the system, which can be more efficient and flexible for many tasks compared to graphical interfaces.

Using a CLI can speed up workflows for tasks that may be repetitive or complex to complete through a graphical user interface (GUI). For users who are proficient in the commands and syntax required, a CLI can offer powerful control over the operating system and applications. Additionally, CLIs are often used for scripting and automation, enabling advanced users to create and execute scripts that simplify their interactions with the system.

In contrast, visually-based interaction tools typically rely on graphical elements, which is distinct from the textual nature of a CLI. An online help system is a resource for users to find assistance and documentation about commands and functions, but it does not represent the interface itself. Similarly, a network configuration tool may utilize a graphical or textual interface, but it is a specific application rather than a form of interaction with the operating system as a
