Command Line, Shell Scripting, Terminal#
A command-line interface (CLI) is a type of user interface that allows users to interact with a computer by typing commands at a command prompt. In contrast to a graphical user interface (GUI), which uses visual elements such as icons and menus to interact with the computer, a CLI uses text-based commands that are typed into a command prompt. A CLI can be used to perform a wide variety of tasks, such as running programs, accessing files, and configuring the operating system. CLI’s are often used by advanced users who prefer the flexibility and control that they offer over GUI’s.
