Unlike other Linux based systems, “crontab -e” won’t work on the Synology NAS.
Modifying crontab and enabling the deamon
- Become root
- Edit /etc/crontab
- Restart the cron deamon by typing:
synoservice -restart crond
Note: After a shutdown or reboot, you’ll need to restart the cron deamon to enable it again.
Running tasks using a different user account
If you want to run a task under a different user than root you can do the following:
#min hour mday month wday who command 30 0,6,12,18 * * * root /bin/su -c "/var/services/homes/myuser/apps/flexget.sh" myuser
The task above will run a flexget script under the username myuser ever 4 hours.
