Link checker
From Freephile Wiki
When you have a website, you need to constantly tend the garden of links you have. Links go missing unfortunately. Some tools you can use:
- Ht://Check An oldy but goody.
- LinkChecker probably the most modern and easy to use. Written in Python and code is on GitHub https://github.com/wummel/linkchecker There is a package for Ubuntu (and maybe others?)
- checklink is a Validator by the W3C Use it online, or download the CPAN module
