Hello SigmaX,
I think the following script solves your problem.
-----------------------------------------------------------cut--------
#!/bin/bash
clear
read -p "seconds to wait: " value
time2wait=0
SECONDS=0
while [ 0 ];
do
    netstat -a|grep tcp
    echo "press ctrl-c to exit"
    while [ $time2wait -lt $value ];
    do
 time2wait=$SECONDS
    done
    clear
    time2wait=0
    SECONDS=0
done
-----------------------------------------------------------cut--------
If you want to understand how this works, please execute: man bash

greeting,
Martin
