Linux下RAR安装及相关命令
下载安装包：
http://www.rarlab.com/download.htm
或
http://www.rarsoft.com/download.htm

使用命令进行安装：
#tar -zxvf rarlinux-3.9.3.tar.gz
#cd rar
#make
#make install

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_2.4′ not found (required by rar)
#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。
