Here is another great utility to run the system's daily, weekly, and monthly maintenance scripts (located at /etc/daily, /etc/weekly, and /etc/monthly). These scripts are normally run between 3am and 5am, and will not be run if you shut off your Mac at night. But with MacJanitor, you can run these scripts by hand periodically and keep your Mac's system databases from getting too large.
