Ubuntu中的xz命令使用的方法及命令

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接下来进行如下操作：

# 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

Usage: xz [OPTION]... [FILE]...

-f, --force force overwrite of output file and (de)compress links
-c, --stdout write to standard output and don't delete input files
-0 ... -9 compression preset; default is 6; take compressor *and*
decompressor memory usage into account before using 7-9!
-e, --extreme try to improve compression ratio by using more CPU time;
