checkURL.pl - Check that all the URLs in the Perl source are valid
This program checks that all the URLs in the Perl source are valid. It checks HTTP and FTP links in parallel and contains a list of known bad example links in its source. It takes 4 minutes to run on my machine. The results are written to 'uris.txt' and list the filename, the URL and the error:
404 Not Found
It should be run every so often and links fixed and upstream authors notified.
Note that the web is unstable and some websites are temporarily down.
To install less, copy and paste the appropriate command in to your terminal.
perl -MCPAN -e shell
