Question

It is sometimes necessary to be alerted when a change is made to a web-page.

Currently, I have some simple scripts on OpenBSD that download the web-page with lynx -width 120 -dump, get relevant parts of it with grep -v and -B3 -A3 etc, save it to a special folder under a date-based filename, keep track of the latest two versions with ln -fs, and finally perform the diff, all run from cron.

The scripts work, however, they look a bit ugly, fragile and may not necessarily handle some edge cases. Is there perhaps some existing software that can do this task better and more streamlined?

Explanation / Answer

I found the free Android app Web Alert very useful for this case. It is also one of the very few that can work with webpages that require you to log-in beforehand or submit some form sheet.
