In FC the users crontab files are located in /var/spool/cron. Periodic crontab scripts that are run regularly (hourly, daily, weekly, monthly, etc. are in the appropriate /etc/cron.XXXX directories. In /etc/cron.daily I see the script tmpwatch (/etc/cron.daily/tmpwatch) which seems to me to do what you are asking and more. I never see any old files existing except the ones that are excluded in that script. FC has a default procedure for keeping /tmp cleared. If you need something more specific, you could either write your own script or modify the default and it will work for you. > > - /etc/sysconfig/crond (which doesn't contain the text) > > This looks like it's the equivalent file for FC.
