title: using | column -t in a bash script
body: <p>I am attempting to use <code>| column -t</code> at eh end of a df command in a simple script, and I keep getting an error. </p>
  
  <p>Here is my script:</p>
  
  <pre><code>#!/bin/sh
  CMD=`df -Pi | column -t`
  echo $CMD
  </code></pre>
  
  <p>this is the output that happens when I run it:</p>

  <p>It's all 1 big blob. I'm assuming I'm missing some wrapping characters to the actual command, but I haven't been able to find anything. </p>
  
  <p>This is the output I am looking for from a script:</p>
