DTYPE(C) UNIX System V
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 filesystems and backup 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.
Value Added
dtype is an extension of AT&T System V provided by the Santa
Cruz Operation.
