Why doesn Snoopy offer positive reinforcement when no errors are found?
Snoopy used to output the phrase Perfect! when no errors were found, offering some satisfaction to developers. This “feature” was later removed so that Snoopy could run more effectively as a cron job. For most cron systems, outputting any content to screen will result in an email being sent containing that output. Generally, you don’t want to receive an email unless something has gone wrong. So Snoopy now only prints output to screen when it encounters errors. Consider no news to be good news.
