Hi guys - Relatively new to shell programming so please bare with me (I bet everyone says that!)

I'm faced with a problem:

I need a shell script to do the following:

I need to do this to integrate this into a larger college project. I found a resource online with the following script which pings values from a HOSTS variable and emails on a report but I need to integrate a lot more functionaliy obviously. I'd apreciate if anyone has any pointers / tips on how to do the above.

HOSTS="google.com msn.com"

# no ping request
COUNT=1

# email report when
SUBJECT="Ping failed"
EMAILID="me@mydomain.com"
for myHost in $HOSTS
do
count=$(ping -c $COUNT $myHost | grep 'received' | awk -F',' '{ print $2 }' | awk '{ print $1 }')
if [ $count -eq 0 ]; then
# 100% failed
echo "Host : $myHost is down (ping failed) at $(date)" | mail -s "$SUBJECT" $EMAILID
fi
done
