No, it means Sunday through Sunday (0 and 7 both mean Sunday for day of week), at 20 to 1 in the afternoon (crontab uses the 24 hour clock), the command 'eprints reboot' will be attempted. If you don't have a command 'eprints', it will fail. Check root's mailbox for more details of the error output, and check man 5 crontab for more details of how the crontab file works. > The problem is, nothing appears to be happening.
