title: Is 'status' a keyword in bash?
body: <p>On Centos7, I have a Bash script like the following</p>
  
  <pre><code>#!/bin/bash
  echo "Hello there"
  status=$?
  </code></pre>
  
  <p>In my vim editor window, the "status" word is highlighted red, but any other word in its place will be highlighted pink. Is "status" a reserved word in Bash? If so, what's its default purpose?</p>
