What is a command based interface in programming?

A command-based interface in programming is a user interface that allows users to interact with a computer system by typing commands in text format, rather than using graphical elements like buttons or menus. It typically involves a command line or terminal where users input specific commands to execute tasks, such as file manipulation or program execution. This interface is often favored by advanced users for its speed and efficiency, as it provides direct access to system functionalities without the need for a mouse or graphical navigation. Examples include UNIX shells and Windows Command Prompt.
