What is Command Line Interface?
A command-line interface (CLI) is a text-based user interface (UI) used to run programs, manage computer files, and interact with computers. CLSs are also called command-line user interfaces or console user interfaces or character user interfaces.
The two types of operating system shells are GUI and CLI.
CLI-based shells provide a concise and efficient way for users to interact with the OS, without requiring the overhead of a graphical user interface. GUI-based shells are considered easy to use for beginners, but they also consist of a CLI-based shell for system administrators or power users who prefer to interact at the command prompt.
A command-line processor uses a command-line interface (CLI) to receive commands from the user in the form of lines of text. It provides a means of setting parameters for the environment, implementing executables, and providing information about what tasks they should perform. In some cases, the invocation is conditional based on conditions established by the user or the previous executable.
