title: Bash: output line count from wc in human readable format
body: <p>Is that possible? Doing <em>wc</em> the straight forward way I have to spend some mental energy to see that the file contains more than 40 million lines:</p>
  
  <pre><code>$ wc -l 20150210.txt 
      45614736 20150210.txt
  </code></pre>
  
  <p>I searched around and <em>numfmt</em> showed up, but that is evidently not available on OSX (nor on <em>brew</em>). So is there a simple way to do this on OSX? Thanks.</p>
