However, due to the way the QNAP firmware updates crontab, it will be overwritten on the next reboot. Obviously, you want your automation to survive reboots, so edit the crontab file directly with your text editor: ``` vim /etc/config/crontab ``` When you're done, reload the crontab file and restart the cron daemon: ``` crontab /etc/config/crontab && /etc/init.d/crond.sh restart ``` ## Gute Quellen * Bash-Skripte: https://wiki.ubuntuusers.de/Shell/Bash-Skripting-Guide_für_Anfänger/ * Cronjobs: https://www.stetic.com/developer/cronjob-linux-tutorial-und-crontab-syntax.html
