Command-line interface

ACommand-line interface(CLI), Also knownCommand-line user interface,Console user interface, AndCharacter user interface(Cui), Is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines ).

The CLI was the primary means of interaction with most computer systems until the introduction of the video display terminal in the mid-1960s, and continued to be used throughout the 1970 s and 1980 s on UNIX systems and personal computer systems including MS-DOS, CP/M and Apple DOS. the interface is usually implemented with a command line shell, which is a program that accepts commands as text input and converts commands to appropriate operating system functions.

Command-line interfaces to computer operating systems are less widely used by casual (casual; informal; temporary; accidental) computer users, who favor graphical user interfaces. command-line interfaces are often preferred by more advanced computer users, as they often provide a more concise (concise, concise) and powerful means to control a program or operating system.

Programs with command-line interfaces are generally easier to automate (automate, enable automatic operations) via scripting.

Alternatives to the command line include, but are not limited to text User Interface menus (see ibm aix Smit for example), keyboard shortcuts, and varous other desktop metaphors centered on the pointer (usually controlled with a mouse ).
