DTYPE(C) XENIX System V DTYPE(C)
Name
dtype - Determines disk type.
Syntax
dtype [-s] device ...
Description
dtype determines type of disk, prints pertinent information
on the standard output unless the silent (-s) option is
selected, and exits with a corresponding code (see below).
When more than one argument is given, the exit code
corresponds to the last argument.

Notes
word-swapped refers to byte ordering of long words in
relation to the host system.
XENIX file systems and dump and cpio binary formats may not
be recognized if created on a foreign system. This is due
to such system differences as byte and word swapping and
structure alignment.
This utility only works reliably for floppy diskettes.
