command-line interface

a means of operating a computer by typing a text command at an on-screen prompt and hitting the Enter or Return key to issue the command. The computer then processes the command, displays whatever output is appropriate, and presents another prompt for the next command. Typical commands are to run a program, enter a text editor, list files, and change directories. This mode of interaction is common, for instance, in the traditional DOS and UNIX operating systems.
