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

NAME

     mount_hfs -- mount an HFS/HFS+ file system

SYNOPSIS

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

DESCRIPTION

     The mount_hfs command attaches the HFS file system residing on the device special to the global file system namespace at the location indi-
     cated 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 supported:

	     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 system.  (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 separated string of options.  See the mount(8) man page for possible options
	     and their meanings.

     -j      Ignore the journal for this mount.

     -c      Disable group commit for journaling.

     -w      Mount the HFS wrapper volume.

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

BUGS

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

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

NAME

     mkfs.hfs -- construct a new HFS Plus file system

SYNOPSIS

     mkfs.hfs [-N [partition-size]] [-U uid] [-G gid] [-M mask] [-h | -w] [-s] [-b block-size] [-c clump-size-list] [-i first-cnid]
	      [-J [journal-size]] [-n node-size-list] [-v volume-name] special

DESCRIPTION

     mkfs.hfs builds an HFS Plus file system on the specified special device.

     The file system default parameters are calculated based on the size of the disk partition. Typically the defaults are reasonable, however
     mkfs.hfs has several options to allow the defaults to be selectively overridden.  The options are as follows:

     -N [partition-size]
		 Causes the file system parameters to be printed out without really creating the file system.

     -U uid	 Set the owner of the file system's root directory to uid.

     -G gid	 Set the group of the file system's root directory to gid.

     -M mask	 Specify the access permissions mask for the file system's root directory.

     -h 	 Creates a legacy HFS format filesystem. This option is not recommended for file systems that will be primarily used with Mac OS X
		 or Darwin.

     -s 	 Creates a case-sensitive HFS Plus filesystem. By default a case-insensitive filesystem is created.  Case-sensitive HFS Plus file
		 systems require a Mac OS X version of 10.3 (Darwin 7.0) or later.

     -w 	 Adds an HFS wrapper around the HFS Plus file system.  This wrapper is required if the file system will be used to boot natively
		 into Mac OS 9.

     -b block-size
		 The allocation block size of the file system.	The default value is 4096.

     -c clump-size-list
		 This specifies the clump and/or initial sizes, in allocation blocks, for the various metadata files.  Clump sizes are specified
		 with the -c option followed by a comma separated list of the form arg=blocks.

		 Example:  -c c=5000,e=500

		 a=blocks    Set the attribute file clump size.

		 b=blocks    Set the allocation bitmap file clump size.

		 c=blocks    Set the catalog file clump size.

		 e=blocks    Set the extent overflow file clump size.

     -i first-cnid
		 This specifies the initial catalog node ID for user files and directories. The default value is 16.

     -J [journal-size]
		 Creates a journaled HFS+ volume.  The default journal size is 8MB.  Appending an 'M' to the journal size implies megabytes (i.e.
		 64M is 64 megabytes).	The maximum journal size is 512 megabytes.

     -n node-size-list
		 This specifies the b-tree node sizes, in bytes, for the various b-tree files.	Node sizes are specified with the -n option fol-
		 lowed by a comma separated list of the form arg=bytes. The node size must be a power of two and no larger than 32768 bytes.

		 Example:  -n c=8192,e=4096

		 a=bytes     Set the attribute b-tree node size.

		 c=bytes     Set the catalog b-tree node size.

		 e=bytes     Set the extent overflow b-tree node size.

     -v volume-name
		 Volume name (file system name) in ascii or UTF-8 format.
