I have a perl script that basically moves directories from one server to another. In it is a line using rsync that does this: 
my $rsync_command = 'rsync -vrlte "ssh -p '.$pref_values->{'SSH_PORT'}
+.' -l '.$pref_values->{'SSH_USER'}.' -o StrictHostKeyChecking=no" --p
+rogress';
my $cmd = `$rsync_command "$full_dir_name"/* $pref_values->{'SSH_SERVE
+R'}:$home_dir_name`;

I'm moving some large directories over the internet, so oftentimes this command takes 20 or 30 minutes. I'd like to somehow grab the output of the rsync command and update a database with the progress. Right now, I'm only adding a line that says started, and a line that says done. On occasion the script crashes, or the connection is interrupted, etc. So when I see Started, I have to log into the target server and check the directory size to see if it's still growing. The output of this command when I run it manually looks like this: 
File1
          1,282 100%    0.00kB/s    0:00:00 (xfr#1, to-chk=23/24)
File2
          1,064 100%  346.35kB/s    0:00:00 (xfr#2, to-chk=22/24)
File3
      3,506,176  10%  121.86kB/s    0:04:17  ^C

Is there anyway to poll this command and get the output while it's running? I know I can grab it at the end and insert a summary, but I want to be able to look in my database and see that I'm 10% of the way through File3, it's going at 121 kB/s and there's 4:17 left on that file. Thanks!
