Command Line Interface

Command Line Interface is an interface in which, we have to give command for each and every step.
Here, we have to study all the needed commants for the running of each and every applications.
A program that implements such a text interface is often called a command-line interpreter, command processor or shell. The term 'shell', often used to describe a command-line interpreter, can be in principle any program that constitutes the user-interface, including fully graphically oriented ones—for example, the default Windows GUI is created by a shell program named EXPLORER.EXE, as defined in the SHELL=EXPLORER.EXE line in the WIN.INI configuration file.

CLI is manly used in 1970's and 80's.

 

 

The main disadvantage of CLI is that it is not user friendly.
We have to byheart all the commands.

The main advantage is that here, user is in direct contact with the system.

e.g :  MS-DOS, CP/M, Unix, and Apple DOS
