I want to write a crontab entry to run every 30 minutes for the last week of every month. I know to do the final Sunday for instance the cron is:
0 0/30 * ? * 0L
When I try to comma separate the weekday field like so:
0 0/30 * ? * 0L,1L,2L,3L,4L,5L,6L
I get an error:
Support for specifying 'L' with other days of the week is not implemented
Is there a way to short hand this crontab expression, or do I need to make 7 separate crontab entries each with a different day?
