DESCRIPTION

     The hfs.util command supports the mounting, probing, and unmounting of HFS file systems.

     Options:
	   -a	       Adopt permissions for the HFS file system at device
	   -I	       Print out status information about the journal on the HFS file system at mountpoint
	   -J [size]   Enable journaling on the HFS file system mounted on mountpoint.	An optional size may be specified (e.g. 32M for a 32
		       megabyte journal).
	   -k	       Get the UUID key for the HFS file system at device.
	   -m	       Mount the HFS file system located on device onto mountpoint with the flags mountflag1 mountflag2 mountflag3 mountflag4
	   -M	       Force mount the HFS file system located on device onto mountpoint with the flags mountflag1 mountflag2 mountflag3
		       mountflag4.  This is a deprecated option.
	   -N	       Disable journaling on a HFS+ file system located at device
	   -p	       Probe the device for an HFS file system using the flags mountflag1 mountflag2 mountflag3 mountflag4
	   -s	       Set the UUID key (generates a new UUID value) for the HFS file system at device
	   -u	       Unmount the HFS file system located at device
	   -U	       Disable journaling on the HFS+ file system mounted on mountpoint

     The mountflags referenced above are either:
	   o   removable or fixed
	   o   readonly or writeable
	   o   suid or nosuid
	   o   dev or nodev

     Note that for the device references above, you must only supply the last component of the path to the device in question, such as disk0s2
     rather than /dev/disk0s2.
