title: Issue with scheduling a bash script with crontab
body: <p>Using:</p>
  
  <pre><code>20 21 * * *  /bin/sh /Users/username/Documents/first.sh
  </code></pre>
  
  <p>to execute my script which does btw have this at the top:</p>
  
  <pre><code>#!/bin/sh
  </code></pre>
  
  <p>and instead I am getting this:</p>
  
  <pre><code>You have new mail in /var/mail/username
  </code></pre>
  
  <p>with the following output:</p>
  
  <pre><code>/Users/username/Documents/first.sh: line 3: wget: command not found
  /Users/username/Documents/first.sh: line 4: wget: command not found
  </code></pre>
  
  <p>How do I fix this?</p>
