While our country hosted the president of Russian Federation Vladimir Putin, Ladislav held his lecture about Cron in the cozy and funny atmosphere here at Sipod.
Cron is a Linux utility which schedules a command or script on your server to run automatically at a specified time and date. A cron job is the scheduled task itself. Cron jobs can be very useful to automate repetitive tasks. Scripts executed as a cron job are typically used to modify files or databases. However, they can perform other tasks that do not modify data on the server, like sending out email notifications.
Using Cron, a developer can automate such tasks as mailing ezines that might be better sent during an off-hour, automatically updating stats or the regeneration of static pages from dynamic sources. Systems administrators and Web hosts might want to generate quota reports on their clients, complete automatic credit card billing, or similar tasks.
