I want to shedule a task for 8.30am every Monday, for every month, for every year...
What would the UNIX Crontab format be?
You would put the crontab entry like this:
The first field is minutes, the second is hours, and the fifth is days of the week (where Sunday is 0).
When I was starting out with Linux/UNIX, I found something like this was quite useful.
I think this one is slightly easier to use.
