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
