    Please don't add code as pictures especially if it's a oneliner this only proves lazyness – derHugo Aug 1 '17 at 15:45
  1. Your line is commented out so never performed
    -> delete the # at the start

  2. It should be * * * * * for every minute

  3. (Thanks to @Rinzwind) reboot does not work It has to be
    systemctl reboot -i

So in the end in your file there should be the line

* * * * * systemctl reboot -i

-i here stands for ignore-inhibitors. Some programs put this inhibitors lock to prevent dataloss so you wouldn't reboot but get a note in the command line.

This should do the trick

Note: Not letting unmentioned here that this doesn't seem a smart idea to me ... Why do you want that? And make sure you are able to revert this before your system reboots again when you don't want this anymore ;)

  • Well it has a lot to do with the question.. but I see and accept what you mean. – derHugo Aug 1 '17 at 15:44
  • This is correct, but the answer is incomplete. Usually reboot command needs 'sudo' rights, so this must be written in root's crontab - sudo crontab -e, or in /etc/crontab or somewhere in /etc/cron.d/. It is also recommended to use the fill path to the program within crontab, so we can write which reboot to find it... – pa4080 Aug 1 '17 at 15:51
  • I'm pretty sure the image already shows the file edited by sudo crontab -e .. the question is incomplete in information though. Usually those are already performed with root permissions – derHugo Aug 1 '17 at 15:53

    @pa4080 nope. reboot does not But the command is wrong. systemctl reboot -i is the command to use. – Rinzwind Aug 1 '17 at 17:51
  • @Rinzwind thanks didn't know that. Actually for certain reason never tried this before until I came home now but you are right. Edited my answer – derHugo Aug 1 '17 at 20:38
