没有特殊原因，文档如果要传到linux上，一定要打成*.zip格式，这样方便解压，一般来说没有理由要用rar，关于
linux上unzip命令有空细讲，本节讲下，如何让linux支持解压缩rar文件?
一 、系统环境
1. 系统环境
实验环境一：CentOSrelease5.5(Final)
2.6.18-194.el5
x86_64GNU/Linux
实验环境二：CentOSrelease5.4(Final)
2.6.18-164.el5
i686GNU/Linux
2. 命令查看方法[root@oldboytools]#cat/etc/redhat-release
CentOSrelease5.5(Final)
[root@oldboytools]#uname-r
2.6.18-194.el5
[root@oldboytools]#uname-m
x86_64
二、下载并安装rar软件
1. 下载mkdir-p/home/oldboy/tools
cd/home/oldboy/tools
wget/rar/rarlinux-3.8.0.tar.gz
2. 安装tarzxvfrarlinux-3.8.0.tar.gz
cdrar
make
makeinstall
三、rar命令语法
将/etc 目录压缩为etc.rar 命令为：raraetc.rar/etc
将etc.rar 解压 命令为：rarxetc.rar
unrar-eetc.tar
四、具体例子
实例：将/etc 目录压缩为etc.rar[root@oldboytools]#raraetc.rar/etc
