As Florian explained, crontab syntax gets weird when you use fields 3 and 5. Basically, what you want to do cannot be done in a plain crontab. You might be able to leverage anacron to accomplish what you want. Otherwise, you must write a wrapper script that runs daily or on Mondays and checks a flag file that it creates and only run once in a given month -- Alan McKinnon [email protected]
