        Greetings all,
        I'm trying to set up a cronjob to turn off my UBports powered Nexus 5 each day at a certain time.

        Here is what I did from a terminal:

        sudo su
        mount / -o rw,remount
        crontab -e
        (here is my crontab entry made, and saved via Nano: 30 19 * * * shutdown -h now)
        (to auto shutdown at 7:30pm each day)

        The cronjob is not running (at least the phone is not shutting down as I would expect).
        I noticed that the crontab file I modified is located in the /tmp directory so I suspect that it is being deleted each time the phone reboots. Perhaps there is another way or place to modify the cronjob as root?

        Any ideas or help much appreciated.

          Forced to find a solution elsewhere, I finally decided to edit the crontab file directly (located at /etc/crontab). Making the change directly instead of using crontab -e worked for me. I generally don't like editing that file directly since errors can cause all cronjobs to fail.

            @rek769 Interesting. Thanks for the sharing the info. I wonder how apps can be started from cron, or vice versa.
