What type of software interface allows users to execute commands using text input?

The command-line interface (CLI) is a type of software interface that allows users to interact with the computer system by typing text commands into a console or terminal. This interface is primarily text-based, meaning that it does not use graphical elements like buttons or icons to facilitate user interaction. Instead, users need to be familiar with specific command syntax to perform tasks, such as navigating directories, executing programs, or managing files.

The primary advantage of using a command-line interface is its efficiency for users who are comfortable with text-based commands. It often requires less system resources than graphical user interfaces and can provide powerful capabilities for advanced users who need to automate tasks through scripting or wish to access features that may not be available in a GUI.

In contrast, graphical user interfaces rely on visual elements that users interact with through point-and-click actions. Touch interfaces use gestures on a touchscreen for interaction, while voice user interfaces allow users to execute commands through spoken language. Each of these interfaces caters to different user preferences and use cases, but they differ fundamentally from the text command interface of a CLI.
