There is this log file, which we would like to keep an eye on. Usually it does not receive any updates. But once or twice a week it gets updated and when it does we want to be notified about it.
Is there any way to routinely check (cron-job) and detect changes in such a text file and have linux send out an email about the change. It would also be great if the email would include the new lines, but we can live without the latter wish.
