Questions tagged [command-line-interface]

The interface to a program that consists entirely of text, as opposed to (although not necessarily mutually exclusive to) a GUI, or Graphical User Interface.

A command line interface (CLI) is an interface to a program based on a series of typed text lines, called commands, which follow a specific language structure. The command lines are then interpreted by a Command Language Interpreter (more commonly known as a Shell).

The CLI was a popular interface since the 1960's, and even with development of more modern UI experiences such as , it is still a ubiquitous interface today.
