Hi monks
I am tring to open the remote file from remote host by
using Net::Telnet module,i suceeded in that.But my actual
task is to develop a script which should opens the file and it internally checks the perticular username is present,
if that user name is not there means,i have to pass the username and other parameters from the commandline.

Below is my code and also the remote file format
that i have to append.

#!/usr/bin/perl -w
$arg=$ARGV[0];
$arg1=$ARGV[1];
$prompt = "bash-2.03\#";
#print "$prompt\n";
use Net::Telnet;
$telnet = new Net::Telnet(Timeout=>10,prompt=>"/$prompt/i",Errmode=>'d
+ie');
$telnet->open("xxx.xx.xxx.xxx");
$telnet->waitfor('/login: $/i');
$telnet->print('xxxx');
$telnet->waitfor('/password: $/i');
$telnet->print('xxxxxx');
$telnet->waitfor("/$prompt/i");
@arr=$telnet->cmd('cat aa.txt');
foreach(@arr)
{
  @arr1=split/:/,$_;
  if($arr1[0]=~/$arg/)
    {
      print"user exist\n";
    }
       else {
               @arr=push @arr,$arg1;
               print @arr;
            }
}
     print @arr;

the above script will opens the file from remote server,
after that i parsed the first field of each line i.e
user name,when i run this script with existing user name as argument it prints "username exist",if the argument not
matches with the existing username,then it should append
the file with that argument at remote host. keep pouring your ideas.
