Khen , i am able to login and list files using the following code now, but not able to get the files

use strict;
use warnings;
use Net::SFTP;

my $host = "hostname";
my $user = "username";
my $remote = './trade_080417_121605.csv';

my $ssh= Net::SFTP->new($host , user=>$user,ssh_args => [ identity_fil
+es => [ "/etrade/home/ibia_ir/.ssh/id_rsa"],debug => '1']);
