Schedule your script to run every Sunday.

Now, the date of any first Sunday of the month (or any first ***day of the month for that matter ) will always fall between the 1st of the month and the 7th of the month, since there are only 7 days on a week.

So, the first Sunday of the month can only be the 1st, 2nd, 3rd, 4th, 5th, 6th, or .the 7th.

So, at the beginning of your script, you are going to make a variable that will be equal to the extracted day number from the date command, and add a small if statement, and if that number is higher than 7, you script should exit.

Like this:

Code:

DATE=$(date '+%e')

if (( ${DATE} > 7 )); then
   exit 0
else
   run your script
fi

Thanks, that script is probably the best solution, I was just hoping cron had something in it to do this but I guess not. Thanks for all help.

	      ini_set('intl.default_locale', 'en_US');

	      var_dump(IntlDateFormatter::formatObject($cal, 'cccc')); // Wednesday

	      var_dump($cal->getMinimalDaysInFirstWeek(), // 1
	      $cal->getFirstDayofWeek()); // 1 (Sunday)

	      // Week 1 of 2013
	      var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));
