AIX cron job is running everyday instead of on a particular day
Hello,

I was trying to run a script on a dev server using cron job. It supposed to run 3rd sunday of every month.
Code:
45 4 15-21 * 0 /home/user1/myscript.sh >/dev/null 2>&1 # run this script 3rd sunday of every month

When I Schedule it on AIX server, It is running every day at 4:45 AM.
am I doing anything wrong ?

I am thinking to try below, please suggest.

Code:
45 4 15-21 * 7 /home/user1/myscript.sh >/dev/null 2>&1 # run this script 3rd sunday of every month

But It is same as "0" for sunday.

How about below ?

Code:
45 4 15,16,17,18,19,20,21 * 0 /home/user1/myscript.sh >/dev/null 2>&1 # run this script 3rd sunday of every month


Please suggest.

Thanks,
Kumar

		       is the minute number.

       result	       The result of the  su(1M) command.  A ` + ' sign is displayed in this field if the su attempt was successful; otherwise	 a
