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

newfs_hfs -- construct a new HFS Plus file system SYNOPSIS
newfs_hfs [-N] [-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
Newfs_hfs builds an HFS Plus file system on the specified special device. Before running newfs_hfs the disk should be partitioned using the Disk Utility application or pdisk(8). The file system default parameters are calculated based on the size of the disk partition. Typically the defaults are reasonable, however newfs_hfs has several options to allow the defaults to be selectively overridden. The options are as follows: -N 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 recomended 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.

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

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.
