Re: [Expectperl-discuss] help!!

[Alan J. <al...@ra...>]

Thanks for the prompt reply. As you have suggested, I have included the 
script below. Maybe that can give you a clue as to what is going wrong. 
Thanks for the help.

-----------------------------------------------------------------------------
#!/usr/bin/perl

use Expect;

#change the source and destination path here!
$ssh=Expect->spawn("rsync -avzu --delete --progress --stats --rsync-path /path-to-rsync -e ssh /source-path account\@xxx.edu:/destination-path");


# No changes needed from here on
$ssh->expect(10,"ssword: ") || die "Never got password prompt on rci.rutgers.edu, ".$ssh->exp_error()."\n";

# We got the prompt, so send a password.
    print $ssh "xxxxxxx";
    $match=$ssh->expect(10,"closed by foreign host","-re",'[%>$]\s');
    die "Files have been updated on xxx.edu\n" unless $match;
    $ssh->hard_close();
