今天拿到一个包，后缀名为：xz
经查询，用xz-utils中的xz命令可以对其进行解压。
在Ubuntu-11.04下面进行如下操作：
# aptitude search xz
得如下结果：
p xz-lzma – XZ-format compression utilities – compatibility commands p xz-utils – XZ-format compression utilities p xzdec – XZ-format compression utilities – tiny decompressors p xzgv – Picture viewer for X with a thumbnail-based selector p xzip – Interpreter of Infocom-format story-files p xzoom – magnify part of X display, with real-time updates
于是安装xz-utils
# sudo apt-get install xz-utils
完成后，，查看帮助：
# xz –help
