Description:
tool to verify the links in a web page are still valid
The checklink tool is a program that reads an HTML or XHTML document, extracts a list of anchors and links and checks that no anchor is defined twice and that all the links are dereferenceable, including the fragments. It warns about HTTP redirects, including directory redirects, and can check recursively a part of a web site. The program can be used either as a command line tool or as a CGI script. The official site is available as http://validator.w3.org/checklink.
