NAME

       dcopy - copy HFS file system with compaction

SYNOPSIS

       fsize[source_fs destination_fs

DESCRIPTION

       The command copies an existing HFS file system (source_fs) to a new HFS file system (destination_fs), appropriately sized to hold the reor-
       ganized results.  For best results, the source file system should be a raw device, and the  destination	file  system  should  be  a  block
       device.	Always run on unmounted file systems.  (In the case of the root file system, copy it to a new minidisk.)

       If no options are specified, copies files from source_fs, compressing directories by removing vacant entries and spacing consecutive blocks
       in a file by the optimal rotational gap.  If options such as or are specified, the destination file system structure will be different from
       that of the source file system.

       makes  the  destination file system identical to the source file system and preserves the pack and volume labels.  Thus, to compress a file
       system without moving it, use to copy the files to another file system and the command to copy the file back (see dd(1)).

       Directory compression is accomplished by running on the primary copy of the file system and allowing the modified directories to  propagate
       to the other copies of the file system in the normal manner.

   Options
       recognizes the following options:

	      Move subdirectories to the beginning of directories.

	      Specify the file system size
			     (fsize)  and  inode-list  size  (isize)  in blocks.  If this option is not specified, the source file-system value is
			     used.

	      Specify the HFS file system type.
			     The type of a file system can be determined with the command (see fstyp(1M)).  See

	      Supply device information
			     for creating the best organization of blocks in a file.  cyl is the number of block per cylinder; skip is the  number
			     of blocks to skip.

	      Report size of source and destination file system.

	      Echo the completed command line, but performs no other actions.
			     The  command  line  is  generated by incorporating the user-specified options and other information derived from This
			     option allows you to verify the command line.

EXAMPLES

       can be executed with or without options.  If no options are specified as in this example, the source and destination file systems are iden-
       tical.  Any differences between the two file systems lie only in the available disk space.

       If options are specified, expect a major difference between the source and destination file system structure:

WARNINGS

       produces invalid results if run on a mounted file system.

       The figures specified in option arguments cannot be smaller than corresponding figures in the source file system.

DEPENDENCIES

       only operates on HFS file systems.

NAME

       mkfs - construct a file system (generic)

SYNOPSIS

       FStype] specific_options] special
	      [operands]

       FStype] special

DESCRIPTION

       The  command  creates  a file system by writing on the special file special.  operands are listed on file-system-specific manpages (see the
       section).

   Options
       recognizes the following options:

	      Specify the file system type on which to operate (see
			     fstyp(1M) and fs_wrapper(5)).  If this option is not included on the command line,  then  the  file  system  type	is
			     determined  from the file by matching special with an entry in that file.	If there is no entry in then the file sys-
			     tem type is determined from the file

	      Display the command line that was used to create the file system.
			     The file system must already exist.  This option provides a means of determining the parameters used to construct the
			     file system.

	      Specify options specific to the file system type.
			     specific_options is a list of suboptions and/or keyword/attribute pairs intended for an FStype-specific module of the
			     command.  See the file system specific manual entries for a description of the specific_options that  are	supported,
			     if any.

	      Echo the completed command line, but perform no other action.
			     The  command  line  is  generated by incorporating the specified options and arguments with other information derived
			     from This option allows the user to verify the command line.

EXAMPLES

       Execute the command to create a 32MB HFS file system on

       Execute the command on an HFS file system, to recreate the command that was used to create the file system on
