dtype(C) 19 June 1992 dtype(C) Name dtype - determine disk type Syntax dtype [-s] device ... Description The dtype command determines the type of a disk and prints pertinent in- formation on the standard output (unless the silent (-s) option is selected), then exits with a corresponding code (see below). When more than one argument is given for device, the exit code corresponds to the last argument.

XENIX filesystems and backup and cpio binary formats may not be recog- nized if created on a foreign system. This is due to such system differ- ences as byte and word swapping and structure alignment. This utility only works reliably for floppy diskettes.
