[SOLVED] My Cron is not working

[Ejdaha]

HI all
I've created cron file and it's entry is as below:

28 * * * * ls -lh > /tmp/aa.txt

But it doesn't running in every 28th minute of hour. What may be the reason?
I've created it as below:
[ejdaha@localhost]crontab -e
Changed it .. then give a list
[ejdaha@localhost]crontab -l
See my cron there.
But it doesn't work ..

Thanks for suggestions

try putting you command as

/bin/ls

I changed it to full address, now its working. But my sh file is not working. My crontab's entry is :
* * * * * /home/oracle/sh/test.sh

What may be the reason?
Thanks.

have you given execute permission to your "test.sh"
then try changing it to "/bin/sh /home/oracle/sh/test.sh"
(it may not work) test it.
to execute shell script from CLI it should be initiated with "./" or "sh"

I solved this problem by exportin all Oracle's Environment variables
