I'm not responding fast because of that wording. Please do not use "urgent" or anything like that in your posts. You can get demerits and penalties for that, and we wouldn't want that to happen. :eek: You will make the moderators very unhappy when you use that wording. There is a separate emergency forum where you can spend all those bits you have earned, to get the fastest possible response. Anyway, here is a way to do it, and I hope it helps:

$ cat file.txt
10.223.20.1
205.171.3.25
10.223.20.3
206.190.36.45
10.223.10.5
198.105.251.23

$ cat ping.sh
while read ip; do
  ping -c 1 $ip > /dev/null 2> /dev/null
  if [ $? -eq 0 ]; then
    status=up
  else
    status=down
  fi
  echo $ip $status
done < file.txt

$ ./ping.sh
10.223.20.1 down
205.171.3.25 up
10.223.20.3 down
206.190.36.45 up
10.223.10.5 down
198.105.251.23 down

The

  ping -c 1 $ip > /dev/null 2> /dev/null
  if [ $? -eq 0 ]; then

can be simplified

  if ping -c 1 $ip > /dev/null
  then

A more professional solution is

fping < file.txt

Google for download fping
