title: Execute bash file from Python
body: <p>I want to execute a shell script file from within Python. I am currently using Envoy to do this:</p>
  
  <pre><code>envoy.run('./scripts.sh')
  </code></pre>
  
  <p>But it throws me a <code>No such file or directory</code> error.</p>
  
  <p>I am wondering, under which path is the above file executed? How can I make the above script run? It is located in the same directory as the Python script.</p>
