I know you know. I know too :smiley:

My answer was a vain attempt at humour.

From your question is utterly impossible to know what you want.

What "entire program"? To do what?

5

Which Operating System and version? The syntax for "ping" varies widely.

6

solaris and aix

i don't know exactally ver?

Are you, perhaps, under the assumption that 'ping' is a shell script? If so, we have to disappoint you, as it's a binary program with widely different code across OS', probably written in C on most.

This is what i got for you in my archive which i used it in AIX quite long time ago, i hope it helps you...

# cat host
150.150.102.10
150.150.105.10
150.150.106.10
150.150.150.150
# cat pn
while read hostname
do
PL=$(ping -c 10 $hostname | grep "% packet" | awk '{gsub("%","",$0);print $7}')
 if [[ $PL -gt 50 ]]
  then
  echo "$hostname is not pinging" >> status
  else
   echo "$hostname is pinging" >> status
  fi
done < host
# cat status
150.150.102.10 is pinging
150.150.105.10 is not pinging
150.150.106.10 is pinging
150.150.150.150 is not pinging

on Solaris, I found this,

bash-3.00$ uname -a
SunOS your_host 5.10 Generic_127111-11 sun4u sparc SUNW,Sun-Fire-V440
bash-3.00$ /usr/sbin/ping your_host
your_host is alive
bash-3.00$ echo $?
0
bash-3.00$ /usr/sbin/ping invalid_host
/usr/sbin/ping: unknown host invalid
bash-3.00$ echo $?
1
bash-3.00$

you can have something like this:

/usr/sbin/ping your_host >/dev/null 2>&1
status=$?
if [ "$status" -eq "0" ]; then
 echo "ping success"
else
 echo "ping failed"
fi

Are you planning to create something that will check the state of the servers?
I mean if it is pingable is up if not is down?

Ping varies over platforms and versions, but it tends to return a code that is reliable to consistent so that 'if ping ${target}' works.

You do need to be more clear and complete with such questions.
