7zip 9.20安装后不支持rar格式的文件，需附加安装其他文件，首先下载2个源码包

http://sourceforge.net/projects/p7zip/files/p7zip/9.20.1/

p7zip_9.20.1_src_all.tar.bz2 和 p7zip_9.20.1_x86_linux_bin.tar.bz2

先将p7zip_9.20.1_src_all.tar.bz2解压，进入解压后的文件夹p7zip_9.20.1中

执行./install.sh 命令后出现一下提示表示安装成功

这时p7zip已经安装完成，可以运行7za命令，但7za命令无法解压rar文件，还需要安装另一个源码包：

在解压p7zip_9.20.1_x86_linux_bin.tar.bz2，此时会默认将这个包里的内容也解压到p7zip_9.20.1文件夹中

这时p7zip_9.20.1文件夹中会多出一个bin目录，安装bin/Codecs/Rar29.so

或者将p7zip_9.20.1_x86_linux_bin.tar.bz2解压出来的文件夹(可以删除之前解压出来的7zip_9.20.1文件夹)放到指定的软件安装目录中，将bin目录下的7z和7z.so文件复制到/usr/sbin目录中，此时就可以使用7z命令来解压rar文件了。

对于Window下的常见压缩文件.zip和.rar，Linux也有相应的方法来解压它们：

1)对于.zip

linux下提供了zip和unzip程序，zip是压缩程序，unzip是解压程序。它们的参数选项很多，可用命令zip -help和unzip -help查看，这里只做简单介绍，举例说明一下其用法：

# zip yajiu.zip yajiu.jpg yajiu.png这条命令是将yajiu.jpg和yajiu.png压缩成一个zip包# zip yajiu.zip *.jpg这条命令是将所有.jpg的文件压缩成一个zip包# zip -r yajiu.zip yajiu这条命令是将文件夹yajiu压缩成一个zip包# unzip yajiu.zip这条命令是将yajiu.zip中的所有文件解压出来

2)对于.rar

安装： sudo apt-get install rar unrar

或者可从http://www.rarsoft.com/download.htm下载 RAR for Linux 编译安装# tar -xzpvf rarlinux-3.8.0.tar.gz# cd rar# make这样就安装好了，安装之后就有了rar和unrar这两个程序，rar是压缩程序，unrar是解压程序。它们的参数选项很多，可用命令rar -help和unrar -help查看，这里亦简单举例说明一下其用法：

# rar a yajiu.rar yajiu.jpg yajiu.png这条命令是将yajiu.jpg和yajiu.png压缩成一个rar包# rar a yajiu.rar *.jpg这条命令是将所有.jpg的文件压缩成一个rar包# rar a yajiu.rar yajiu这条命令是将文件夹yajiu压缩成一个rar包# unrar e yajiu.rar这条命令是将yajiu.rar中的所有文件解压出来
