title: "No such file or directory" error when calling fc-list in python
body: <p>I am attempting to scrape a terminal window of the list of fonts installed on the curent hosting server. I have written the following code:</p>
  
  <pre><code> import subprocess
   cmd = 'fc-list'
   output = subprocess.Popen(cmd, stdout=subprocess.PIPE ).communicate()[0]
  </code></pre>
  
  <p>but when i call this code, an exception is raised:</p>
  
  <blockquote>
    <p>[Errno 2] No such file or directory</p>
  </blockquote>
  
  <p>I can open a terminal window, and this works fine. What am i doing wrong?</p>
