Checklinks is yet Another HTML Link Checker (in Perl 5). Features include SSI (.shtml) support, direct file reads where possible, HTML 4.0, HTTP 1.1, and aliases and other server options. Other useful but more common features include regular expressions to restrict the URLs searched and results reported, and a detailed verbose report.
