select  , 專門做菜單用的 。只是移植性差 ，之適合 ksh 和 bash。

#!/bin/bash
OPTIONS="Route Ls iptables iptablesADD iptablesDEL Quit"
select opt in $OPTIONS; do
if [ "$opt" = "Quit" ]; then
#echo done
echo ByeBye
exit
elif [ "$opt" = "Route" ]; then
route -n
elif [ "$opt" = "Ls" ]; then
ls -l
elif [ "$opt" = "iptables" ]; then
iptables -t nat -L
elif [ "$opt" = "iptablesADD" ]; then
echo -n "lease input IP:"
read IP
iptables -t nat -A POSTROUTING -s $IP -j MASQUERADE
elif [ "$opt" = "iptablesDEL" ]; then
echo -n "lease input number:"
read DIP
iptables -t nat -D POSTROUTING -s "$DIP"/32 -j MASQUERADE
else
clear
echo bad option
fi
done
