Cron schedule for every last monday of every month

[Sridhar]

Hi

   I am planning to scheduled a cron job which need to run every 4th monday of every month @ 8 Am. Can  any one help me on this..

0 08 23-31 * 1 <script>  

Is this correct or any modification needed.

I believe it's day 22-28 (check August 2011 and November 2011 as the first and last possibility of 'every 4th monday of every month)

you can't do what you're wanting strictly with cron.

you need to add coding within your script to test the date to know whether or not to proceed.

Donna is right - at least the search function is also not that bad, check this one:

Right.

Note: that last Monday isn't the same as 4th Monday.

And to make your script simple, include the date range in crontab and check for Monday in your script:

0 08 25-31 * * <script>  last

0 08 22-28 * * <script>  4th
