CRON jobs

[lenag]

Hello

I need to create the following cron jobs:
job #1: runs Mon,Tue,Wed,Thu,Fri,Sun at 9PM every month except for 15th
job#2: runs on 15th of each month at 9PM
job #3: runs every Saturday at 6PM every month


What is the correct syntax for this kind of scheduled cron jobs?

Thanks,
Lena

If you go into a terminal and run the command "man 5 crontab", you will get a page of documentation explaining crontab. This includes information on the format of the crontab file.

Alternatively, you can go to Wikipedia and see the information there:

I know how to use documentation.
I'm asking for help to post exact syntax for this scenario.
The one I already have doesn't work.

Hello and welcome!

If you'll post what you have now, someone might be able to help you figure out why it's not working.

# normal backups w/ cleanup
10 21 1-14,16-31 * 0,1,2,3,4,5 /export/home/oracle/scripts/rmanscriptinc1 > /export/home/oracle/logs/cronrmaninc1.out 2>&1
10 18 * * 6 /export/home/oracle/scripts/rmanscriptinc0 > /export/home/oracle/logs/cronrmaninc0.out 2>&1
# backup entries with cleanup
#10 18 * * 6 /export/home/oracle/scripts/rmanscriptinc0 > /export/home/oracle/logs/cronrmaninc0.out 2>&1
10 21 15 * 0,1,2,3,4,5 /export/home/oracle/scripts/rmanscriptinc1_cleanup > /export/home/oracle/logs/cronrmaninc1.out 2>&1

What happened yesterday is that both scripts rmanscriptinc1 and rmanscriptinc1_cleanup ran even though rmanscriptinc1_cleanup is only scheduled to run once a month on 15th.

Thanks,

Google: cron examples

5,10 	0 	10 	* 	1 	– At 12.05,12.10 every Monday & on 10th of every month

I don't think it will work in my case.
In your example you have the same job scheduled, and in my case I need to schedule 2 separate jobs.

Q.

What happened yesterday is that both scripts rmanscriptinc1 and rmanscriptinc1_cleanup ran even though rmanscriptinc1_cleanup is only scheduled to run once a month on 15th.

A.

NO, it's not.

5,10 	0 	10 	* 	1 	– At 12.05,12.10 every Monday & on 10th of every month

Let's read the example AGAIN.

10 21 1-14,16-31 * 0,1,2,3,4,5 /export/home/oracle/scripts/rmanscriptinc1 > /export/home/oracle/logs/cronrmaninc1.out 2>&1

This is scheduled for dates 1-14, 16-31 AND Sun > Fri - like it says in any CRON example/link/documentation.
