linux下如何解压缩rar文件呢？

请看下面的介绍。

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

实验环境二：

CentOS release 5.4 (Final)

2.6.18-164.el5

i686 GNU/Linux

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

mkdir -p  /home/oldboy/tools

cd /home/oldboy/tools

wget http://files.keray.com/winrar/rarlinux-3.8.0.tar.gz

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、例子

实例：将/etc 目录压缩为etc.rar

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