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 !

jwhois(1)						      General Commands Manual							 jwhois(1)

NAME
jwhois - client for the whois service SYNOPSIS
jwhois [ OPTIONS ]... [ QUERY ] DESCRIPTION
jwhois searches Whois servers for the object on the command line. The host to query is taken from a global configuration file, a configuration file specified on the command line, or selected directly on the command line. OPTIONS
--version display version, authors and licensing information. --help display a short help text. -c FILE --config=FILE uses FILE as a configuration file instead of the default. -h HOST --host=HOST overrides any hosts in the configuration file and queries HOST directly. -p PORT --port=PORT specifies a port number to use when querying a HOST. -f --force-lookup forces a query to be made to a host even if a current object is available from the cache. -v --verbose outputs verbose debugging information while running (use this before sending a bugreport to ensure that it's indeed a bug and not a misconfiguration). You can increase the verbosity by giving several verbose commands to jwhois, such as -vv. -n --no-redirect disable features that redirect queries from one server to another. -s --no-whoisservers disable the built-in support for whois-servers.net. -a --raw send query verbatim to receiving hosts instead of rewriting them according to the configuration. -i --display-redirections display every step in a redirection (default is to display only the last answer). -d --disable-cache completely disable both reading and writing to cache. -r --rwhois force the query to use the rwhois protocoll instead of HTTP or whois. --rwhois-display=DISPLAY asks receiving rwhois servers to display the results in the DISPLAY display instead of the default dump display. --rwhois-limit=LIMIT asks receiving rwhois servers to limit their responses to LIMIT matches. RIPE EXTENSIONS To use the options specified in RIPE Document 157, you need to change the format of the query slightly. If you were to search for all entries in the RIPE database which lists the admin-c, tech-c or zone-c as CO19-RIPE, you could use the following command syntax: jwhois -h whois.ripe.net -- -i admin-c,tech-c,zone-c CO19-RIPE -- is used to separate the RIPE options from the jwhois options.
