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
[root@oldboy tools]# uname -r
[root@oldboy tools]# uname -m
x86_64
二、下载并安装rar软件
2.1 下载
mkdir -p /home/oldboy/tools
cd /home/oldboy/tools
2.2 安装
tar zxvf rarlinux-3.8.0.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

我安装rar之后出现下面错误：
运行 rar --help 可以看到帮助信息，如果出现下列信息：
#rar: /lib/tls/libc.so.6: version `GLIBC_2.7' not found (required by rar)
则执行：
#cp -f rar_static /usr/local/bin/rar
这样就可以使用rar 命令了。
RAR 命令与winrar 命令基本一致，只是在 windows 下使用 winrar 命令，在 liunx 下使用 rar 命令。
