[SOLVED] shell script to shutdown/restart Linux system

Issue

Is there any suitable shell script for shutting down or restarting a Linux machine? I have tried a shell script for shutdown, but when I enter sudo shutdown it will ask for the password. How we can enter the password using the script?

Solution

Yes, use the -S switch which reads the password from STDIN:

$echo <password> | sudo -S <command>

So to shut down the machine, your command would be like this (just replace <password> with your password):

$echo <password> | sudo -S poweroff

Exposing your password is generally bad idea search for something that can protect / hide it. In the past I've used Jenkins plugins to do this while executing the scripts regularly.
