Which of the following is NOT a feature of Command-Line Interfaces?

A Command-Line Interface (CLI) is characterized by its reliance on text-based input, allowing users to interact with the operating system or software by typing commands into a terminal window. Since a CLI primarily operates through textual commands rather than graphical elements, it does not typically provide a visual representation of options like buttons, icons, or menus.

Support for keyboard shortcuts (option A) is indeed a common feature in CLI environments, enhancing user efficiency and command execution speed. Text-based input (option C) is fundamental to how CLIs function, emphasizing direct command input instead of graphical manipulation. Direct interaction through terminal commands (option D) is the essence of a CLI; users enter commands to execute processes directly.

The absence of a visual interface in CLIs clearly differentiates them from graphical user interfaces (GUIs), which do provide such visual representations. Thus, recognizing that CLIs do not incorporate visual representation helps in understanding their fundamental characteristics.
