fstyp_msdos

/sbin/fstyp_msdos
Check for an MSDOS FAT volume

The fstyp_msdos utility is not intended to be run directly, but rather called by fstyp while it is trying to determine which file system type is present on the given device. It returns 1 if it thinks the device contains an MSDOS FAT volume, and 0 otherwise.
