NAME

     apfs_hfs_convert -- convert an existing HFS file system to APFS file system

SYNOPSIS

     apfs_hfs_convert [-D] [-g] [-e] [-v] [-i] [-S path] [-n] [-f] [-F index] [-M mount_path] [-o nx-apfs-format] <device-path>

DESCRIPTION

     The apfs_hfs_convert command converts an existing HFS file system to a new APFS file system.

     It is recommended not to run the apfs_hfs_convert directly, but to run `diskutil apfs convert`.

     The device-path parameter should be the path to a disk device node, such as /dev/disk1s2, with an existing HFS file system, which needs to be
     converted.  The device-path may be a path to a whole disk, such as /dev/disk0, which contains Lightweight Volume Manager (LwVM) structures;
     all HFS slices will be converted and LwVM replaced by a GPT partition map with a single partition containing the APFS container.

     The options are as follows:

     -e | --estimate	   Estimate the APFS metadata size after conversion.

     -v | --verbose	   Increase verbosity of the output.

     -s | --force-case-sensitive
			   Force the converted volume to be case-sensitive. By default, the converted volume will have the same case-sensitivity
			   as the original HFS volume.

     -S path | --stats path
			   Print statistics about the conversion to the supplied path.	If the path is - then the statistics are printed to
			   standard output.

     -n | --dry-run	   Do not finalize the conversion to APFS. Volume remains HFS.

     -f | --force	   Force conversion if volume is dirty (journal is non-empty, volume had inconsistencies, or volume is not journaled and
			   not unmounted cleanly).

     -F index | --fixed index
			   Volume number index (0-based) should be formatted as fixed-size.  Usually used when converting LwVM.

     -M mount_path | --mount-path mount_path
			   When converting LwVM systems, which require a special "conversion mount" of the underlying device, use the given
			   mount_path as the mount point.  If this option is not used, a temporary directory will be created and used.

     -o nx-apfs-format	   NX or APFS format options.

     -g 		   If conversion succeeds, modify the GPT UUID.

     -D | --skip-single-dirlinks
			   Convert all former and current directory hardlinks to files/aliases.

DIAGNOSTICS

     The apfs_hfs_convert utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     The following converts the HFS file system on the /dev/disk1s2 device:
	   apfs_hfs_convert -v /dev/disk1s2

NAME

       hmount - introduce a new HFS volume and make it current

SYNOPSIS

       hmount source-path [partition-no]

DESCRIPTION

       hmount is used to introduce a new HFS volume. A UNIX pathname to the volume's source must be specified. The source may be a block device or
       a regular file containing an HFS volume image.

       If the source medium is partitioned, one partition must be selected to be mounted. If there is only one HFS partition  on  the  medium,	it
       will  be  selected by default. Otherwise, the desired partition number must be specified (as the ordinal nth HFS partition) on the command-
       line. Partition number 0 can be specified to refer to the entire medium, ignoring what might otherwise be perceived  as	a  partition  map,
       although in practice this is probably only useful if you want this command to fail when the medium is partitioned.

       The  mounted  volume becomes "current" so subsequent commands will refer to it.	The current working directory for the volume is set to the
       root of the volume.  This information is kept in a file named .hcwd in the user's home directory.

       If the source medium is changed (e.g. floppy or CD-ROM disc exchanged) after hmount has been called,  subsequent  HFS  commands	will  fail
       until the original medium is replaced or a different volume is made current. To use the same source path with the different medium, reissue
       the hmount command.

EXAMPLES

       % hmount /dev/fd0
	      If a Macintosh floppy disk is available as /dev/fd0, this command makes the floppy current for other HFS commands  such  as  hls(1),
	      hcd(1), hcopy(1), etc.

       % hmount /dev/sd2 1
	      If  a  SCSI disk is available as /dev/sd2, this command finds the first HFS partition on the medium and makes it available for other
	      HFS operations.

NOTES

       hmount does not actually mount an HFS partition over a UNIX directory in the traditional mount(8) sense. It is merely a "virtual" mount, as
       a point of convenience for future HFS operations. Each HFS command independently opens, operates on, and closes the named source path given
       to hmount.
