Cron question
 

I need a script to be runned by cron each 4 minutes so i should use

*/4

in minutes field. But what if i need that script to be runned each 4 minutes but exactly at 00, 04, 08, 12, 16, 20, 24, etc.? (= not for example 03, 07, 11,...) May i use

00,*/4

as correct syntax? It should do that in first 00 it will be runned although previous run could be at 59 and then it goes to each 4 minutes. Am i guessing it well or is it nonsense?

hey peter,

Love that thing

Simply */4 should do it...

You can control it like this:

0-59/4

or if you want it to run at 01, 05, ...

1-59/4

Hope this helps

very nice. :thumbsup
