Answer

#!/bin/bash

# IPS=$(ifconfig | awk '/inet/ { print $2 }' | awk -F ":" '{ print $2 }')
IPS="192.168.23.5 47.45.56.11 189.67.24.21"
count=1

for IP in $IPS;
do
IP[$count]=$IP;
echo "Found IP $count - ${IP[count]}";
count=`echo $count+1 | bc`
done


read -p "Which IP do you want to use? (number)" choice

IPCHOICE=${IP[$choice]}
echo "Your choice was $choice - Setting IP to $IPCHOICE "


# ifconfig ...
