Problems such as these may occur from time-to-time, and a Linux administrator will be called upon to provide a solution. Let's take the previous problem and add an additional element. Let's assume that the high-school is used throughout the day and night (i.e. night-school). Let's assume that the only time that the system can be rebooted is between midnight and 7 am. Obviously, the high-school teacher (nor myself) want to say up twice a week after midnight to reboot the system. Therefore, it would make sense to have this shell script (run as the "administrator") automatically for a specificied date and time...

... thus we would use '''cron'''. The cron command or utility stands for "'''Chronograph'''" and is a '''time-based scheduler for programs''' (like shell scripts).
