title: Check progress of cURL
body: <p>Is there some way to check the status of a curl command?  Say, I have a call to curl from php, using exec to initiate it.  Is there a way I can check the progress of it while it's running?  Or do I have to wait for it to finish?</p>
  
  <p>exec("curl $url -k > /dev/null 2>&amp;1 &amp;");</p>
