title: Bash script to run command on all files in folder fails
body: <p>I would like to run this command on all .wa files within this folder (ideally with subfolders):
  ./runtest Basic prog -t abc.wa</p>
  
  <p>The script I wrote returns an error:</p>
  
  <pre><code>for filename in ./examples/*.wa;
  do
      ./runtest Basic prog -t "${filename}"
  done
  </code></pre>
  
  <p>When running this with ./testscript I get:
  Syntax error: word unexpected (expecting "do")</p>
  
  <p>Can the script also add to the console output the name of the current file?</p>
