mount_hfs(8)              BSD System Manager's Manual             mount_hfs(8)


     mount_hfs -- mount an HFS/HFS+ file system


     mount_hfs [-e encoding] [-u user] [-g group] [-m mask] [-o options] [-j]
               [-w] [-x] special directory


     The mount_hfs command attaches the HFS file system residing on the device
     special to the global file system namespace at the location indicated by
     directory.  This command is normally executed by mount(8) at boot time.

     The options are as follows:

     -e encoding (standard HFS volumes only)
             Specify the Macintosh encoding. The following encodings are sup-

             Arabic, ChineseSimp, ChineseTrad, Croatian, Cyrillic, Greek,
             Hebrew, Icelandic, Japanese, Korean, Roman (default), Romanian,
             Thai, Turkish

     -u user
             Set the owner of the files in the file system to user.  The
             default owner is the owner of the directory on which the file
             system is being mounted.  The user may be a user-name, or a
             numeric value.

     -g group
             Set the group of the files in the file system to group.  The
             default group is the group of the directory on which the file
             system is being mounted.  The group may be a group-name, or a
             numeric value.

     -m mask
             Specify the maximum file permissions for files in the file sys-
             tem.  (For example, a mask of 755 specifies that, by default, the
             owner should have read, write, and execute permissions for files,
             but others should only have read and execute permissions.  See
             chmod(1) for more information about octal file modes.)  Only the
             nine low-order bits of mask are used.  The default mask is taken
             from the directory on which the file system is being mounted.

     -o      Options are specified with a -o flag followed by a comma sepa-
             rated string of options.  See the mount(8) man page for possible
             options and their meanings.

     -j      Ignore the journal for this mount.

     -w      Mount the HFS wrapper volume.

     -x      Disable execute permissions on a standard HFS file system.


     mount(2), unmount(2), fstab(5), mount(8)


     Some HFS file systems with highly fragmented catalog files may not mount.


     The mount_hfs utility first appeared in Mac OS X Server 1.0.
