while read site; do
if [ ! -z “${site}” ]; then
echo $site
checker=$(/bin/ping -c4 $site)

if echo $checker | grep “0 received” > /dev/null
echo “The Server on ${site} is down!”

MESSAGE=”This is an alert from MonitorServer that the ping test to the Server ${site} has failed to respond.”

for EMAIL in $(echo $EMAILS | tr “,” ” “); do
