mv (short for move) is a Unix command that moves a file or directory from one place to another. The original file is deleted, and the new file may have the same or a different name.

MVS has been said to be the operating system that keeps the world going and the same could be said of its successor systems, OS/390 and z/OS.
Although MVS has often been seen as a monolithic, centrally-controlled information system, IBM has in recent years repositioned it (and successor systems) as a "large server" in a network-oriented distributed environment, using a 3-tier application model.
MVS is considerably more complex and requires much more education and experience to operate than smaller server and personal computer operating systems.
