This brings up something i have been wondering about for some time. SCO's
Xenix has a "file" program, but it only knows so many types. I sometimes
FTP files from BSD systems and loose part of the filename because of the 
Xenix filename length limit. SCO does not recognize compressed files at,
it just says data. Is the source for a file like program available on the
net? Is there a BSD file program that is free of AT&T code?

On Xenix, the file man page says;

	.
	.
	.
	  If the -f option is given, file takes	the list of filenames
	  from namesfile. If the -m option is given, file sets the
	  access time for the examined file to the current time.
	  Otherwise, the access	time remains unchanged.
