title: How to use the subprocess.check_output comand correctly
body: <p>I want to execute the the shell script <code>generateLicense.sh</code> with different arguments. I do it like that:</p>
  
  <pre><code>License = subprocess.check_output(['./generateLicense.sh -firstargument 1 -secondargument 2 -thirdargument 3'])
  </code></pre>
  
  <p>The shell script is in the same folder as the file that starts the shell script but i always get this error:</p>
  
  <pre><code>OSError: [Errno 2] No such file or directory
  </code></pre>
