command line interface
<operating system> A means of communication between a program and its
user, based solely on textual input and output. Commands are input with the help
of a keyboard or similar device and are interpreted and executed by the program.
Results are output as text or graphics to the terminal.
Command line interfaces usually provide greater flexibility than graphical user
interfaces, at the cost of being harder for the novice to use. Consequently,
some hackers look down on GUIs as designed For The Rest Of Them.
