Debian Ubuntu Update Script with Switch OFF after update

Problem:
I f you work on you PC daily Patches must be checked and installed.
At Debian / Ubuntu the Gnome-Update-Manager does this. But there is
NO Shutdown possible after update.

Solution:
– create Script #sudo nano /root/upgrade-off.sh
add inside:

apt-get update           //for update Patches Database PC
apt-get dist-upgrade -y         //install Patches automatic
apt-get clean      //cleanup PC
/sbin/init 0      //shutdown PC automatic or reboot Server = init 6
exit

You can now after work set it to crontab or start manual by #sudo sh /root/upgrade-off.sh

On Servers name it upgrade-reboot.sh and set root cron to run the job @hourly/@daily
