Ubuntu中的xz命令使用

Ubuntu中的xz命令使用 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  www.2cto.com    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 Usage: xz [OPTION]...
