title: parallel call multiple bash functions
body: <p>I have read the example at <a href="http://www.gnu.org/software/parallel/man.html#example__calling_bash_functions" rel="noreferrer">http://www.gnu.org/software/parallel/man.html#example__calling_bash_functions</a> however, is it possible to use gnu parallel to call 2 functions which do not have any variables you pass to them ?</p>
  
  <p>example</p>
  
  <pre><code>a() {
    echo "download a"
    wget fileA
  }
  
  b() {
    echo "download b"
    wget fileB
  }
  </code></pre>
  
  <p>and use parallel to call both functions <code>a</code> &amp; <code>b</code> ?</p>
