What is command line interface (CLI)?
The command line interface (CLI) is a text-based interface used to operate software and operating systems, while the user can respond to visual prompts by entering individual commands into the interface and receiving a response in the same way.
CLI is fundamentally different from the graphical user interface (GUI) currently used in the latest operating systems.
CLI is an older way of interacting with applications and operating systems and is used to perform specific tasks that users need. CLI is a text-based interface, as opposed to the GUI, which uses graphical options that allow the user to interact with the operating system and applications.
CLI enables a user to perform tasks by entering commands. Its working mechanism is very simple, but not user-friendly. Users enter the specific command, press 'Enter' and wait for a response. Upon receiving the command, the CLI will process it accordingly and display the output / result on the same screen; Command line interpreter is used for this purpose.
CLI wurde mit der Fernschreibermaschine eingeführt. Dieses System basierte auf Batch processing. Moderne Computer unterstützen CLI, Stapelverarbeitung und GUI in einer Schnittstelle.
To get the most out of the CLI, a user must be able to quickly enter a bunch of commands, one at a time. There are many applications (mono processing systems) still using CLI for their operators. In addition, some programming languages such as Forth, Python and BASIC CLI. The command line interpreter is used to implement the text-based interface.
Another feature of the CLI is the command prompt, which is used as a string of characters used in the user interface or shell. The command prompt is used to inform users that the CLI is ready to accept commands. MS-DOS is the best example of CLI.
