For normal programs import sys; sys.exit() You can pass an exit code to the outdside world as a parameter to exit too. or just raise SystemExit will work. > i have an app that i want to start every day at 6am from cron > but i want it to shutdown at 4pm OK, here you probably want system.exit(n) with a proper error code so that cron can tell if it worked or not... BTW strftime('%H') returns the hour in 24 hour format so you will want to check for 16 not 4...
