前言：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

1.1 系统环境实验环境一： CentOS release 5.5 (Final) 2.6.18-194.el5 x86_64 GNU/Linux <–64位系统实验环境二： CentOS release 5.4 (Final) 2.6.18-164.el5 i686 GNU/Linux <–32位系统

1.2命令查看方法： [root@oldboy tools]# cat /etc/redhat-release CentOS release 5.5 (Final) [root@oldboy tools]# uname -r 2.6.18-194.el5 [root@oldboy tools]# uname -m x86_64 二、下载并安装rar软件

2.1 下载( http://www.rarsoft.com/download.htm)

mkdir -p /home/oldboy/tools cd /home/oldboy/tools wget http://www.rarsoft.com/rar/rarlinux-x64-4.2.0.tar.gz

2.2 安装

tar zxvf rarlinux-x64-4.2.0.tar.gz cd rar make make install

三、rar命令语法

将/etc 目录压缩为etc.rar 命令为：

rar a etc.rar /etc

将etc.rar 解压命令为：

rar x etc.rar unrar -e etc.tar

四、具体例子

实例：将/etc 目录压缩为etc.rar

[root@oldboy tools]# rar a etc.rar /etc

将etc.rar 解压： [root@oldboy tools]# rar x etc.rar
