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?

I don't believe cron has any concept of the first day-of-week of each month, so you'll need to put some code into your script to exit if its NOT the first day-of-week of each month.

It certainly doesn't. However, I'm surprised the o/p's crontab entry *doesn't* work: it should run only on Sat, and only on when it's somewhere between the 1st and the 7th, which could only be the first Sat.
