title: How can I wrap each bash command's output in a single blank newline before and after?
body: <p>How can I wrap bash command output so that it is surrounded on top and bottom with a blank newline? </p>
  
  <p>I have trouble picking out the current command's output from the previous command and the next prompt. I've tried <code>PROMPT_COMMAND=echo</code> but this only adds a newline at the end and not the beginning. How can I have both so I can better parse my bash reality?</p>
  
  <p>For example right now I see this:</p>
  
  <pre class="lang-sh prettyprint-override"><code>rjurney$ ls ~/tmp/
  total 312
  -rw-r--r--   1 rjurney  staff    472 Mar 27 16:40 README.md
  rjurney$
  </code></pre>
  
  <p>I want to see the following:</p>
  
  <pre class="lang-sh prettyprint-override"><code>rjurney$ ls ~/tmp/
  
  total 312
  -rw-r--r--   1 rjurney  staff    472 Mar 27 16:40 README.md
  
  rjurney$
  </code></pre>
  
  <p>Thanks!</p>
