title: Even thought I have set the $PATH variable still command not found
body: <p>I am using a Mac. The output of echo $PATH gives: </p>
  
  <pre><code>/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/amazon/bin
  </code></pre>
  
  <p>But when I run </p>
  
  <pre><code>chmod +x mwinit 
  </code></pre>
  
  <p>It gives me the following error:</p>
  
  <pre><code>chmod: mwinit: No such file or directory
  </code></pre>
  
  <p>What am I missing? I have been trying from a long time to fix it. Any help would be appreciated.</p>
