title: Can't make new folder in AWS EC2
body: <p>I am trying to make a new folder to SCP my python script so i can run it on AWS EC2 instance.</p>
  
  <p>So I have SSH and connected to my instance. I tried <code>ls</code> nothing shows.</p>
  
  <p><code>pwd</code> shows:</p>
  
  <pre><code>/home/ec2-user
  </code></pre>
  
  <p><code>mkdir /newFile</code> shows:</p>
  
  <pre><code>mkdir: cannot create directory '/newFile': Permission denied
  </code></pre>
  
  <p><code>sudo mkdir /newFile</code> shows no error. 
  But when I <code>ls</code>, nothing shows. 
  What is happening?</p>
  
  <p><strong>I am using a macbook, and my instance is AWS Linux AMI.</strong></p>
