Execute a command at system startup

[maxcarter99]

Hello everyone !

First of all, I know there are many threads on many websites regarding my issue, but despite all of my efforts, I can't get it work... !

Basically, what I want to do is make a .sh file running when my system boots.

What I've done so far :

• I created a new text editor file, typed in

  sudo shutdown -r 00:00

  so my computer reboots each day at midnight, and saved this file with the extension .sh on my desktop
• I moved the file to the /etc/init.d directory using sudo mv command on terminal
• I did set up executable permission on script with terminal, typing

  chmod +x /etc/init.d/script.sh

• I used the following command to get my file executed at my system startup :

  update-rc.d script.sh defaults 100

Have I done something wrong, or does it miss any step so I can get it work ?

Hope that anyone could help me on that ! Thank you very much.

Remove the sudo from the command.
It's not needed in /etc/init.d and most likely is causing the issue since sudo usually needs user interaction.
You would also most likely need to set the full path to shutdown, /sbin/shutdown should be it.

A much better way to handle scheduled jobs like this is through cron.

sudo echo '00 00 * * * /sbin/shutdown -r now' >> /var/spool/cron/root

That will run the command "/sbin/shutdown -r now" every night at midnight.
