以前的脚本是用save模式，现在把命令附加到一个文件里面，这样的话，可以方便的二次修改什么的

脚本基本是这样的，大家可以跟自己的情况再次修改~ 增加功能什么的。

复制代码 代码如下:

#!/bin/bash

while true

do

clear

echo "----------------------menu----------------------"

echo "(1) service iptables restart"

echo "(2) iptables add"

echo "(3) iptables delete"

echo "(4) iptables stop"

echo "(5) iptables save(不推荐使用这种模式)"

echo "(6) iptables status"

echo "(7) iptables ACL list"

echo "(0) exit"

echo "会在当前的目录下生成一个fw.sh文件"

echo "-------------------------------------------------"

echo -n "enter you chose[0-7]:"

read num
