Linux crawl sitemap and check page itself + images + internal links for 404
<p>I know several ways of crawling using Xenu or other. But there must be a better or smarter way of doing this. </p>

<p>I would</p>

<ul>
<li>like to crawl oour site based on the sitemap</li>
<li>Check for</li>
<li>a) the page itself 404?</li>
<li>b) internal links without params on the page itself 404?</li>
<li>c) all images: do they exist?</li>
</ul>

<p>One could write a PHP script or other. But are there any ready made tools, scripts or maybe Curl that we could use to do this?</p>

<p>THX!</p>
