Well a quick 'n dirty way is:

try to use nmap. it's a lot quicker.

Thanks you very much for the replies.

# Assume list of ip addrs in a file, 1 ip per line
for ip in `cat ips.dat`
do
ping -c1 $ip >/dev/null/ 2>&1
if [[ $? -eq 0 ]]
then
echo "$ip is up"
else
echo "$ip is down"
fi
done

The code really helped me.i have just made modifications according to my requirment

Thanks u very much
