...or at least the best one I've managed to come up with.
cron utility has some well-known shortcomings,
chief among which is how difficult it is to monitor the health and output of
scheduled tasks. The default setup tries to email output, but on a typical
laptop, desktop workstation, or even on many servers, it's common to not have
a working system-wide mailer configuration. Many users therefore set up
“wrapper” scripts that handle logging, timestamping, and so forth. This is the
best one I've managed to come up with.
