Mounts HFS and HFS+ filesystems into the directory hierarchy.

Options

-a

Enables (adopts) permissions on the volume, creating an entry for it in /var/db/volinfo.database if one does not already exist. Unlike disktool -A or vsdbutil -a, this functions only on an unmounted volume.

-J

Enables journaling on the volume.

-k

Reads the disk’s UUID key and prints it to standard output. Functions only on an unmounted volume.

-m

Mounts the device.

-M

Attempts to force the mount.

-p

Probes the device, and prints the volume name to standard output.

-s

Generates a new disk UUID key and sets it on the volume. Functions only on an unmounted volume.

-u

Unmounts the device. This function doesn’t appear to work.

-U

Disables journaling on the volume.

device

The disk device filename, e.g., disk0s5.

mount_point

The directory on which the filesystem is mounted.
