I need a script to take input in the form of a server name, perform the nslookup command, output only the actual IP server address (not the DNS server) and print the output. I have part of the script but need help on the rest. Thanks.

______

#!/usr/bin/bash

echo “Enter a ServerName.\n”
read serverName
nsLook = $(echo nslookup $serverName | egrep -o “Non*" | # this is the part where I need help with getting the last IP address
print nsLook

echo “Do you have another?\n”
case:
    yes)
        next;;    # this is the part where I need help
    no)
        break;;
