Java Command-Line-Interpreter (CLI)

A simple text-based interface for interacting with your operating system. Users can input commands through the keyboard and press enter, and the CLI will parse and execute the indicated commands. The CLI will keep accepting different commands until the user enters "exit" which will terminate it.
