Re: [CentOS] run script on cron job only run on first Saturdat every month???

From: mcclnx mcc mcclnx@yahoo.com.tw

we have CENTOS 5.5 on DELL server.  One of our script need run on first Saturday every month.

We have following setup on cron job but it run every Saturday.

15 04 1-7 * 6 /home/app/oracle/backup/monthlybk.sh

Any one know how to fix it?

That's pretty clever, and it looks like it should work. Maybe something is taking priority? I'd try some experimentation.  Try:

15 04 1-7 <today.day.number> 6 touch /tmp/foo.test

15 04 1-7 <today.day.number> * touch /tmp/foo.test

15 04 1-7 * * touch /tmp/foo.test

15 04 * * 6  touch /tmp/foo.test

etc. It might take a while, but you'll find it eventually!

I had a similar problem with Debian, but it turned out to be a weird timezone issue confusing me.
