Inquiry:How to make crontab job permanent even after server reboot?

hadimotamedi · 10-27-2009, 06:28 AM

Dear All
Please be informed that I have an application that needs my Linux server to be rebooted automatically at pre-specified times . To this end , I set its crontab as the followings :
30 15 * * * reboot
But after the first server reboot , the crontab job will be lost and the other subsequent reboots will not get through . Can you please do me favor and let me know how can I make it as permanent even after server reboot ?
Let me thank you in advance

Rebooting should not alter the crontab at all, check your cron log for more info ( /var/log/cron probably )

Try:
30 15 * * * /sbin/reboot
cron's $PATH isn't set to much, so you may need to specify the /full/path/to/executable
