Command Interpretation

Command Interpreter is the interface between the user and the operating system. Many commands are given to the operating system by control statements. when a new job is started, or when user logs on to the system, a program that reads and interprets control statements is executed automatically. This program is called interpreter or command interpreter. It is also know as shell. The function is to get the next command and execute it.
The Command Interpreter must be user friendly. One style of user friendly interface is the mouse based window in Microsoft Windows. The mouse is moved to position the mouse pointer on images known as icon. Depending upon the position of mouse pointer, clicking a button can open program, select a file or folder or pull down menu that contains commands.
