Just wonder how to run task every 5 minutes.
I dont know what means of comma separated list of minutes.
To run a task every five minutes, you'd need to set the minutes to:
1,6,11,16,21,26,31,36,41,46,51,56
so that each starting minute is 5 apart. So this
2,7,12,17,22,27,32,37,42,47,52,57
would be equivalent, but obviously shifted one minute forward in the hour.
Please note that tasks only run if there are any users on-line at the desired time.
