title: Shell Removing Tabs/Spaces
body: <p>I've used a grep command with sed and cut filters that basically turns my output to something similar to this</p>
  
  <pre><code>    this line 1
  
  
      this line 2
  
  
      another line 3
  
  
      another line 4
  </code></pre>
  
  <p>I'm trying to get an output without the spaces in between the lines and in front of the lines so it'd look like</p>
  
  <pre><code>    this line 1
      this line 2
      another line 3
      another line 4
  </code></pre>
  
  <p>I'd like to add another | filter</p>
