Many of the commands given at this level manipulate files: create, delete, list, print, copy, execute, and so on. The main function of the command interpreter is to get and execute the next user-specified command. Most shells provide similar functionality with only minor differences most users choose a shell based upon personal preference. For example, on UNIX and Linux systems, there are several different shells a user may choose from including the Bourne shell, C shell, Bourne-Again shell, the Korn shell, etc. On systems with multiple command interpreters to choose from, the interpreters are known as shells. Others, such as Windows XP and UNIX, treat the command interpreter as a special program that is running when a job is initiated or when a user first logs on (on interactive systems). Some operating systems include the command interpreter in the kernel. The second approach allows the user to interface with the operating system via a graphical user interface or GUI. One technique is to provide a command-line interface or command interpreter that allows users to directly enter commands that are to be performed by the operating system. There are two fundamental approaches for users to interface with the operating system.
