Broken Link-Checking software/utility

Hi all - I work for an organization that maintains 40 web sites, which run on a UNIX box. We're looking for software that can sit on the UNIX box and check for broken links/orphans on all of our sites....we'd like to schedule it to run nightly and produce a report....anyone know of something that would satisfy these requirements? There are a bunch of solutions out there, but they either don't run on UNIX, or they only check one site, or cannot be scheduled/produce a report.....we need all of those options. Thanks in advance!

Steve

You can use wget or curl for this.
