Command prompt
A command prompt (or just prompt) is a character or string of characters used in a command line interface to indicate that the computer is ready to accept typed input. Common prompt characters include $, #, :, and > and they are often preceded by other information, such as the path name of the current working directory. Command line interfaces are sometimes called "type-at-the-prompt interfaces" and originated in the early days of interactive computing, when slow, but inexpensive teletype machines were used as computer terminals.
