MKEXTUNPACK(8) BSD System Manager's Manual MKEXTUNPACK(8)NAMEmkextunpack — extract or list the contents of a multikext (mkext) archive
SYNOPSISmkextunpack [-v] [-a arch] [-d output_directory] mkext_file
DESCRIPTION
The mkextunpack program lists the contents of a multikext file,
mkext_file, or unarchives the contents into output_directory (which must
exist). The -v option causes mkextunpack to print the name if each kext
as it finds them.
DIAGNOSTICSmkextunpack exits with a zero status upon success. Upon failure, it
prints an error message and exits with a nonzero status.
With a nonsegreated format 1 mkext file, wherein each kext may contain a
universal binary, mkextunpack simply unpacks the contents. With an mkext
file segregated by architecture (that is, with distinct internal archives
of architecture-specific kexts), mkextunpack attempts by default to
unpack or list kexts for the current machine's architecture. To choose a
particular architecture to extract or list, use the -a option.
There is no simple way to unpack a segregated mkext file into a set of
kexts with universal binaries, but you can unpack each of its component
architectures to separate directories for examination.
SEE ALSOkextcache(8)BUGS
Many single-letter options are inconsistent in meaning with (or directly
contradictory to) the same letter options in other kext tools.
For version 1 mkext files, note that the file format doesn't record the
original filenames of the kexts, so mkextunpack has to guess at what they
are. It does this by using the value of the CFBundleExecutable property
of the kext's info dictionary (Project Builder sets this to the base name
of the kext bundle by default, but the developer can change it). If that
property doesn't exist, the last component of the CFBundleIdentifier is
used. Duplicates have an incrementing index appended to the name. Kexts
that have no CFBundleExecutable or CFBundleIdentifier property are named
“NameUnknown-n.kext”, where n is a number.
