前言：沒有特殊原因，文檔如果要傳到linux上，一定要打成*.zip格式，
這樣友善解壓，一般來說沒有理由要用rar.關于 linux上unzip指令有空細講，
本節講下，如何讓linux支援解壓縮rar檔案
一 、系統環境
1.1 系統環境
實驗環境一：
CentOS release 5.5 (Final)
2.6.18-194.el5
x86_64 GNU/Linux <--64位系統
實驗環境二：
CentOS release 5.4 (Final)
2.6.18-164.el5
i686 GNU/Linux <--32位系統
1.2指令檢視方法：
[root@oldboy tools]# cat /etc/redhat-release
[root@oldboy tools]# uname -r
[root@oldboy tools]# uname -m
x86_64
二、下載下傳并安裝rar軟體
2.1 下載下傳
mkdir -p /home/oldboy/tools
cd /home/oldboy/tools
2.2 安裝
tar zxvf rarlinux-3.8.0.tar.gz
cd rar
make
make install
三、rar指令文法
将/etc 目錄壓縮為etc.rar 指令為：
rar a etc.rar /etc
将etc.rar 解壓 指令為：
rar x etc.rar
unrar -e etc.tar
四、具體例子
執行個體：将/etc 目錄壓縮為etc.rar
[root@oldboy tools]# rar a etc.rar /etc

我安裝rar之後出現下面錯誤：
運作 rar --help 可以看到幫助資訊，如果出現下列資訊：
#rar: /lib/tls/libc.so.6: version `GLIBC_2.7' not found (required by rar)
則執行：
#cp -f rar_static /usr/local/bin/rar
這樣就可以使用rar 指令了。
RAR 指令與winrar 指令基本一緻，隻是在 windows 下使用 winrar 指令，在 liunx 下使用 rar 指令。
