Hello,
i need to use cronjobs with the silverstripe framework environment.
In the silverstripe documentation i have found a solution with sake and tasks.
I have three questions/problems with this solution.

1) The Task prints "Running Task MyTitle" always on run. A cronjob should not give output on default. If i pipe this to /dev/null, my full output would removed.
2) How I can control the exitcode. My return value from the run methode was not used.
3) All people has access to run the tasks. My cronjobs should by runable from commandline only

Sorry for my bad english.
Thank you for help.

You can also do this by creating your own custom method in a controller and return nothing and create a cronjob on your webserver.
