IP=`command_system NODE_$node RTR:IP6:ADD | grep -i ".10B" | awk '{print$3}'`
port=`command_system NODE_$node RTR:IP6:ADD | grep -i ".10C" | awk '{print$2}' | cut -c 3- | rev | cut -c 5- | rev`

x="$( cut -d ':' -f8  <<< "$IP" )"
y="$( cut -d ':' -f7  <<< "$IP" )"
z="$( cut -d ':' -f1-6  <<< "$IP" )"

r="$( cut -d ':' -f1-7  <<< "$NEWIP" )"
p=`echo $p | tr [a-z] [A-Z]`
p=`echo "ibase=16; $p-1" | bc`

Try
Code:
[ "$port" != "PORT_C" ] && { read -p"Do you want to run script? " ANS;    [ "${ANS^*}" == "Y" ] && . script; }

and after input Y or N script will continue..

Need following Conditions in script.
1.If Node is connected to port_A and port_B script should ask user where he want to run this script Y or N and then using user input run script.
2.If Node is connected to port_C script will run continue without asking "Do you want to run script?" .



Thanks in Advance

Please read the proposal carefully. It does exactly what you specified: if PORT_A or _B, it asks the user and, if answer is y or Y , it sources a script called "script". If PORT_C, it does not ask and continues the original script.

If you're not happy, be way more precise and detailed in your specification.

Sorry, please use lower case "port_C" for the comparison.

Don't call/source another script, exit the original script.
