FSTYP_HFS(8) System Manager's Manual FSTYP_HFS(8)

fstyp_hfscheck for an HFS volume

fstyp_hfs device

The fstyp_hfs utility is not intended to be run directly, but rather called by fstyp(8) 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 HFS volume, and 0 otherwise.
