NAME
fstyp – identify a file system
SYNOPSIS
fstyp device
DESCRIPTION
The fstyp utility attempts to determine what sort of volume is present on
the given device. It operates by iterating over directories that are
typically part of the path, searching for files matching the pattern
fstyp_* and running them. If it finds a match, it will print out the file
system type name and exit with a return value of 1. If it does not find a
match, it will not print out anything, and the return value will be 0.
