REZWACK(1)                               BSD General Commands Manual                              REZWACK(1)

NAME
     /usr/bin/RezWack -- Combines resource and data forks of a file into a flattened file.

SYNOPSIS
     /usr/bin/RezWack -d dataFork [-do dataForkOffset] -r resFork [-ro resForkOffset] -o outFileName [-f]

DESCRIPTION
     /usr/bin/RezWack takes the data fork of one input file, the resource fork of (possibly the same) file,
     and combines them into a single "flattened" data-fork file.  This file can then be transferred to file
     systems, file servers, or other protocols that do not handle Macintosh HFS resource forks.  QuickTime
     uses this format for "flattened" MooV (.moov or .mov) files.

     /usr/bin/RezWack takes the following flags and arguments:

     -d dataFork
              Path to the file to use as the data fork of the resulting file.  This may be any data file.

     -do dataForkOffset
              Offset from the beginning of the data file from which to start reading the data.  Default is
              the beginning of the file.

     -r resFork
              Path to the file from which to extract resource information.  This must be a data-fork
              resource file (see Notes, below).

     -ro resForkOffset
              Offset from the beginning of the resource file from which to start reading the resource data.
              Default is the beginning of the resource map (byte position 512); note that any other value
              may result in a corrupted resource file when using UnRezWack(1).

     -o outFileName
              Path to the output file to be created.  If the file exists and the -f flag is not provided,
              RezWack will fail with error 2.

     -f       Force overwrite of existing output file.

NOTES
     The HFS and Extended HFS ("HFS+") file systems support two forks for each file in the file system.
     Other file systems may not support multi-fork files, and standard POSIX file system calls do not have
     options to specify which fork to read on a two-fork file.  To use RezWack properly, you must either
     have the resource data in a data-fork resource file, or access the named "rsrc" fork on an HFS or HFS+
     volume.

     Note that on non-HFS volumes, or after using SplitForks(1), the resource data of a file is in a hidden
     file whose name begins with "._".  This is an AppleDouble file that contains the resource data, but it
     is not a resource file and cannot be used with /usr/bin/RezWack or other tools that expect a data-fork
     resource file (such as DeRez(1) ).

     To create the resource data in the data fork, use the -useDF flag to Rez(1).  When the resource data is
     in the data fork of a file, you can use the path to the file as the -r argument regardless of the file
     system.

     If the resource data is in the resource fork of a file on a HFS or HFS Extended file system, you can
     access the resource data using a named fork (for example, the resource fork of ~/foo.txt is
     ~/foo.txt/..namedfork/rsrc).

EXAMPLES
           /Developer/Tools/RezWack -d ~/foo -r ~/foo/..namedfork/rsrc -o ~/foo.wak
           /Developer/Tools/RezWack -d ~/foo.txt -r ~/bar.rsrc -o ~/baz.wak
