.Dd March 29, 2002 .Dt MKEXTUNPACK 8 .Os Darwin .Sh NAME .Nm mkextunpack .Nd extracts the contents of a multikext (mkext) archive .Sh SYNOPSIS .Nm .Op Fl v .Op Fl d Ar output_directory .Ar mkext_file .Sh DESCRIPTION The .Nm program list the contents of a multikext file, .Ar mkext_file , or unarchives the contents into .Ar output_directory (which must exist). The .Fl v option causes .Nm to print the name if each kext as it finds them. .Sh DIAGNOSTICS .Nm exits with a zero status upon success. Upon failure, it prints an error message and exits with a nonzero status. .Sh SEE ALSO .Xr mkextcache 8 .Sh BUGS The mkext file format doesn't record the original filenames of the kexts, so .Nm 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 executable or CFBundleIdentifier are named .Dq NameUnknown-n.kext , where n is a number.
