#!/bin/bash #website test scripts while true;do

        for cycle_temp in `cat websit_url_links`         do

                if  lynx -dump `echo ${cycle_temp}` -accept_all_cookies|grep "true";then                         echo "The website is running naturally"                                          else                         echo "${cycle_temp} has been offline please attend it now!">/opt/test.txt                         mail -v -s "website down mail"  < /opt/test.txt
