Command Line Interface, CLI
Command Line Interface, CLI
The original concept of CLI goes back to the 1950s. It offered instant results for the interaction between teletype machines and computers. Today, the command line interface is widely used with GUIs (graphical users interfaces) found in operating systems and applications provided by Microsoft and Apple. A CLI may be needed whenever a large quantity of commands can be entered much faster as text opposed to a GUI. This is generally the scenario involved with command shell operating systems. Many popular computer scripts such as Lisp, Forth, and Python provide an interactive CLI mode to enable user experimentation.
A command line interface is most often used by program developers and system administrators. It also gets frequent use in scientific environments and by much more advanced computer users.
The command line interface is now being favored by many individuals with visual disabilities, as the commands and all results may be interpreted by way of Braille displays.
