I needed a script to copy a file out to a dmz (using scp), so I wrote this snippet w/ expect. It took a bit of monkeying with it to get it right (especially the part when it gets a "prompt" back from the system), but it works well. (it is functional, just not pretty). "I am more of a butcher than a hacker" Joe 
sub copyover {
    $scp=Expect->spawn("/usr/bin/scp ${srcpath}/$file $who:${destpath}
+/$file");
    $scp->expect(30,"ssword: ") || die "Never got password prompt from
+ $dest:$!\n";
    print $scp 'password' . "\n";
    $scp->expect(30,"-re",'$\s') || die "Never got prompt from parent 
+system:$!\n";
    $scp->soft_close();
    return;
}
