choice

The "choice" command is a useful command line tool available in various operating systems, including Windows and DOS. It allows users to create a prompt that requires a user input or selection from a predefined set of options.

When executed, the "choice" command displays a prompt message and waits for the user to press a key corresponding to the desired option. The options are typically represented by keys or numbers, and the user's selection is returned as an exit code.

This tool is commonly used in batch scripts or command line interfaces where user interaction is required. It provides a simple and convenient way to add decision-making capabilities to scripts.

By default, the "choice" command has a timeout feature, which automatically selects a default option if the user does not respond within a specified time. This is useful for automating tasks or allowing a script to continue execution without manual intervention.

Furthermore, the "choice" command allows customization of the prompt message, the available options, the timeout duration, and the behavior when an invalid input is provided.

Overall, the "choice" command is a versatile and efficient tool for adding interactive elements to command line operations, enabling users to make selections without the need for complex programming.
