title: Formatting list of Amazon EC2 instances from the command line
body: <p>I retrieve data about my current Amazon EC2 instances with <code>ec2-describe-instances -H</code>, which returns something like the following:</p>
  
  <pre><code>Type    ReservationID   Owner   Groups  Platform
  RESERVATION r-xxxxxxxx  xxxxxxxxxxxx    default
  INSTANCE    i-xxxxxxxx  ami-2b5fba42    ec2-xx-xx-xx-xx.compute-1.amazonaws.com ip-xx-xx-xx-xx.ec2.internal running user    0       m1.small    2011-07-12T21:15:39+0000    us-east-1a  aki-xxxxxxxx    ari-xxxxxxxx        monitoring-disabled xx.xx.xx.xx xx.xx.xx.xx         instance-store          paravirtual xen     sg-xxxxxxxx default
  </code></pre>
  
  <p>This looks messy in the OS X terminal. How can I make this output more readable?</p>
