I've got a perl script that automatically logs me via ssh by spawning ssh with Expect.pm. It actually works pretty well and here is my ouput :

$ ngh bestServerEver
GPG Pass : 
root@**********'s password: 
Linux **** 2.6.32-042stab059.7 #1 SMP Tue Jul 24 19:12:01 MSK 2012 x86

bash
[root@******:~]$ bash
[root@******:~]$

I'm trying to suppress this output to get to the server shell directly after typing my command. Like that :

$ngh BestServerEver
root@server#

I've tried that answer :

http://stackoverflow.com/questions/1376607/how-can-i-suppress-stdout-temporarily-in-a-perl-program

I've also tried :

local (*OUT, *ERR);
open OUT, ">&STDOUT";
open ERR, ">&STDERR";
close STDOUT;
close STDERR;
print "don't print";
open STDOUT, ">&OUT";
open STDERR, ">&ERR";

Both are okay when it's about standard STDOUT but Expect seems to be a different kind of handle or whatever. I've also tried setting :

$exp->stty("-echo");

But it did not hide anything Finally, here is the sub that spawns ssh

if you have some tips to give me on how to hide that junk :p

        my ($pConfig,$pass)=@_;

        $exp->spawn("ssh root\@".$pConfig->{'host'});
 
        my $spawn_ok;
 
        $exp->expect(40,
