virtual shredder
     
        The jargon equivalent of the {bit bucket} at shops using
        {IBM}'s {VM/CMS} {operating system}.  VM/CMS officially
        supports a whole bestiary of virtual card readers, virtual
        printers, and other phantom devices; these are used to supply
        some of the same capabilities {Unix} gets from {pipe}s and
        {I/O redirection}.
