cronjob does not executes changes ?

[waldbauer_com]

I recently changed my cronjob via cronjob -e but my changes have not been recognized; i also restarted cron service, but no way. Any ideas ?

Have you checked the cron log? Does that give any clues?

Have you run the modified command/script manually and if so, did it work then?

Have you tried rebooting the NAS?

Rather than editing the crontab, it would be better in my view to create a file in /etc/cron.d with the appropriate ownership and permissions and use that.

It looks like i cannot edit cronjobs via crontab -e

Instead i have to edit the /etc/crontab directly ?

Setup a new cron in cron.hourly now works as expected; however crontab -e does not work at all ...

I think we might overwrite /etc/crontab on firmware updates if I recall correctly so you shouldn't modify that. Adding files in e.g. /etc/cron.hourly as you have done is what you should do.
