pbzx stream parser

This repository is a fork of PHPdev32's implementation of the pbzx stream parser program of which the original source code can be found here. Pbzx is a format employed in later versions of OSX disk images (starting with 10.10) to encode payload data in .pkg files. Pbzx unpacks .pkg files and outputs to stdout to be unpacked with cpio. Note that .pkg files are plain .xar archives.

pbzx SomePkg.pkg | cpio -i  # or
pbzx -n Payload  | cpio -i

To compile pbzx, do

clang -llzma -lxar -I /usr/local/include pbzx.c -o pbzx

If <lzma.h> or <xar/xar.h> are missing, install them with Homebrew using

brew install xz && brew link xz

Install via Homebrew

You can install pbzx via Homebrew now!

$ brew install pbzx
