Help with UNIX Crontab!

Question

I want to shedule a task for 8.30am every Monday, for every month, for every year...

What would the UNIX Crontab format be?

Many thanks

Answer 1

You would put the crontab entry like this:

30 8 * * 1 COMMAND

The first field is minutes, the second is hours, and the fifth is days of the week (where Sunday is 0).

Answer 2

30 8 * * 1

See also 'man 5 crontab'

Answer 3

#minute hour    mday    month   wday
30      8       *       *       1      

Answer 4

30 8 * * 1 <command>

Answer 5

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.
