Crontab Basics

Sep 24, 2009, 08:32 (2 Talkback[s])

"Cron Tab (CRON TABle) is a very cool little thing that allows you to execute scripts at certain times and dates without actually having to be around to do the work. Think of it as setting an alarm to go off at certain intervals, and every time that alarm goes off a certain script is run on your website, for instance. Now I have heard Cron Tab being called many things, often incorrectly. In the circles I travel in we usually refer to it as a Cron-Job. Anyone who has watched a few episodes of Star-Trek will tell you that Cronos is the Klingon Homeworld, although it is actually spelled Q'onos. Another--perhaps less geeky crowd--would tell you that there is a branch of Quantum Physics called Quantum-ChronoDynamics, which deals with the micro- relationships of time and space in quantum forms. These same guys might tell you that the particle hypothesized to be the very particle of time is called a Cronos. Any way you see it, Cronos means time. The TAB part simply comes from table. Hence by working with Cron Tabs we are simply writing Time Tables? Yup! That's about it."
