Hello again

Here is what I've done :

Code:
for HOST in $(cat stations.lst | uniq)
do
  # echo -n "$HOST"
  if ping -c 1 $HOST > /dev/null 2>&1
  then
    HOSTNAME_val=`rsh  $HOST "cp /etc/hosts /etc/hosts.dirty ; sed '/152\.15\./d;/152\.9\./d;/152\.19\./d;/44\.33\./d' /etc/hosts > /etc/hosts.clean ; mv /etc/hosts.clean /etc/hosts"`
    val1=`echo $HOSTNAME_val` 
    echo $val1
  else 
    echo "$HOST ; not responding"
  fi
done

The reason why I did not use the -i option is because many of the workstations are HP-UX and sed does not recognize de -i option on this system...

It's working great, thanks !
