There are many tasks that a server can perform automatically such as running scripts and commands. On a Linux server, the cron utility is used to schedule scripts and commands. 

LIst of Cron jobs are typically located in the spool directories. They are stored in tables called crontabs. You can find them at /var/spool/cron/crontabs. The tables contain the cron jobs for all users, except the root user.
