So the else if will only run if the first if is not true, that doesn't seem right,.

	Hello Mike, Don and Matt,
	
	At the point I am at this list of servers in my script I would really need someone with more experience to see if I even have the right scripting.

If that does not seem right what can I change it to make it right?

	Try something like this:
	
	 my $exp = new Expect;
	
	 $exp->log_stdout(1);
	
	 $username = "XXXXXX";
	
	 $exp->spawn( "ssh -l ${username} ${ip} " ) or die "cannot spawn $command: $! \n";
	
	 $exp->log_file("./${log_dir}/$ip\_info.log");
	
	 print "\nspawning ssh connection to $ip on $time\n\n";
	
	 $exp->log_file->print( "\nspawning ssh connection to $ip on $time\n\n" );
	
	 $exp->expect(8,
	
	 [ 'connecting' => sub { $exp->send("yes \n"); exp_continue; } ],
	
	 [ 'assword:' => sub { $exp->send("$pw\n"); exp_continue; } ],
	
	 [ '-re', '> ?$' => sub { break; }],
	
	 [ 'try again' => sub { die " died from bad password.\n"; }],
	
	 [ 'refused' => sub { die " died from connection refused.\n"; exp_continue; } ],
	
	 [ eof => sub { die " died from eof.\n"; }],
	
	 [ timeout => sub { $exp->hard_close(); }],
	
	 );

	        Now that I have a working script and thanks very much to you Matt and Don,
	
	        I am trying to put in my script an if else because sometimes my script will encounter this :
	
	        Are you sure you want to continue connecting (yes/no)?')
	
	
	
	        what I did create are some variables is this correct and may I see an example if statement so that the script can make a decision and keep going?

	        I think you will want a log file to identify where the script failed.
	
	        I recommend that you take out the 'w' from the $ssh->log_file($filename, 'w'); so it will append to the file rather than over writing it for each server.
	
	        And then put in some sort of header for each server, something like:
	        my $header = "\n\n======= $system =======\n"; $ssh->print_log_file($header);
	
	        Or if you prefer a separate file for each server, then my $filename = "/var/tmp/expect_script_". $system ".log";
	
	        little stuff like this can be very frustrating.

	        Maybe spend a day or two writing some basic perl programs so you feel more comfortable with this stuff. I'm sure there are truckloads of perl tutorials out there.
	
	        I added some context below. You'll need to clean up the leading '>' characters.
