33 04 * * * /usr/bin/date >> /tmp/toto.org
root@mumsa001204:/var/adm/cron# date

If I check cron process

ps -ef|grep cron

root 31672 1 0 Oct 10 - 0:06 /usr/sbin/cron
root 118572 87956 0 21:05:21 pts/0 0:00 grep cron

My problem is this /usr/bin/date >> /tmp/toto.org is not getting executing at all. Will you pl tell me where I am going wrong ?

Thanks for urgent help.

regards
parag

It looks like you want the job to run at 4:33am. If this is true you should have it as 33 4 * * * /usr/bin/date >> /tmp/toto.org. The hour is a 24 hour clock. The hour should be a number from 0 to 23.

Hi,

The crontab entry looks ok - I've got AIX 5.2 systems with the hour field set to 06 instead of 6 and they work ok (even though the documentation says it should be 6).

Take a look at the cron log file /var/adm/cron/log and look to see what happened at 04:33 when your job should have run. If there was an error logged, cron will also have emailed the output to the owner of the job, so call mail under that user and see if anything has been received.

Hope this helps.

Hello,

I had the same problem.
I solved it by putting the script in /usr/local/bin
I still don't have an explenation why, but now it works.

Hi,

Can you paste the output of following commands.

1. ls -l /usr/bin/date
2. crontab -l
3. cat /var/adm/cron/log

thanks

Hello,

One common problem with cron is making changes to the crontab directly without notifying
the cron daemon.

You should use "crontab -e" or "crontab mylocalfilename" instead of editing the file directly.

As you mentioned that you were new to AIX....
Another thing to be aware of is to be careful with just typing "crontab"
It will accept input from standard in, and you may accidentally remove your crontab.
(I have done that a few times by accident...)
Hope this helps,
Casey

ps: Since you said you were new to AIX, here is another tip from personal experience:
There is no command line help for shutdown...Don't even try to look for it, use the man page. :)
