Answers
Explanation:
A command line interface (CLI) is a text-based user interface (UI) used to view and manage computer files. Command line interfaces are also called command-line user interfaces, console user interfaces and character user interfaces.
History and features of CLI
Before the mouse, users interacted with an operating system (OS) or application with a keyboard. Users typed commands in the command line interface to run tasks on a computer.
Typically, the command line interface features a black box with white text. The user responds to a prompt in the command line interface by typing a command. The output or response from the system can include a message, table, list, or some other confirmation of a system or application action.
Today, most users prefer the graphical user interface (GUI) offered by operating systems such as Windows, Linux and MacOS. Most current Unix-based systems offer both a command line interface and a graphical user interface.
The MS-DOS operating system and the command shell in the Windows operating system are examples of command line interfaces. In addition, programming languages can support command line interfaces, such as Python.
An explanation of a shell
The software that handles the command line interface is the shell, also commonly referred to as a command language interpreter. Two well-known shells are Windows shell and Bash for Linux and macOS.
