title: concatenate several file remove header lines
body: <p>What'd be a good way to concatenate several files, but removing the header lines (number of header lines not known in advance), and keeping the first file header line as the header in the new concatenated file?</p>
  
  <p>I'd like to do this in python, but awk or other languages would also work as long as I can use subprocess to call the unix command.</p>
  
  <p>Note:  The header lines all start with #.</p>
