Crontab - Syntax

3 posts in this topic

Hi all, not posted here in a while!!! :hello:

I have setup a Crontab in apache:

15 * * * * path/to/my/php/script

Now I am not sure but does this mean that my crontab will run my script every 15 minutes? or does it mean it will run the script once an hour on the 15th minute?

I have googled a lot this afternoon and could not really find anything that clarified this.

Any help appreciated.

That will run every hour at the 15th minute. For every 15 mins, use

15,30,45,59 * * * * command
