The WEBLINKCHECK-LL script ought to work as written for anyone, whereas weblinkcheck.cron will need some customization.
WEBLINKCHECK-LL -- check for broken links in a webpage;
weblinkcheck.cron -- example of using WEBLINKCHECK-LL on all pages in one or several website(s), automatically fixing broken and moved links.
Note that these scripts are now part of:
ertools.zip -- zipfile containing the webmaster-tools and other bash scripts I've published on this site.
