title: How do I validate my YAML file from command line?
body: <p>I am having issues pulling from a YAML config file:</p>
  <blockquote>
  <p>Fatal error: while parsing a block mapping; expected &lt;block end&gt;, but found block entry</p>
  </blockquote>
  <p>While there are plenty of online YAML validators, which I have tried and have helped, I'd like to validate my YAML files from the command line and integrate this into my continuous integration pipeline.</p>
