title: How to configure curl to only show percentage?
body: <p>Is there an option for the curl command to show only a percentage output to shell rather than all of this, for example:</p>
  
  <pre><code>  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                   Dload  Upload   Total   Spent    Left  Speed
  100 12.4M  100 12.4M    0     0  4489k      0  0:00:02  0:00:02 --:--:-- 4653k
  </code></pre>
  
  <p>Maybe there is a flag I can set? If not, pipe it somehow through a regular expression to show me a continuous update of the percentage only?</p>
  
  <p>Thanks all</p>
