What command is needed for shuting down the system?

[hovzio]

Hi, I've been learning about shell scripts (More like I've been learning bash basics) lately and have started to (attempt to) write some of my own. So far its been going rather well and I'm having a a great deal of fun with it.

To my question. Example: So I have this script that runs for a few hours and I'd like to let it run overnight, is it possible to shutdown the computer from within a bash script?(at the end of it) What is the appropriate command to shutdown the pc? I am new to Ubuntu and Linux so it would be really nice if options and so forth are somewhat defined. I appreciate any help, input, ... on the subject.

Either use "sudo shutdown now -h" or "sudo init 0" to shutdown your system.

Try shutdown.

Read the man page "man shutdown" for the options.

example to shutdown at 8 o'clock:
sudo shutdown 8:00

I use 'halt' ;)

Thanks! Is it possible to use these commands at the end of a shell script?

Yes you could put these at the end of a bash script but they would need to be run with root priveleges to work.

or you could run sudo ./script && halt

[tahnok]

or ./script&&sudo halt if you don't want to give the script root permissions.

Yes you could put these at the end of a bash script but they would need to be run with root priveleges to work....you could also edit the sudoers file so that you can run shutdown -h without having to enter a password. There are plenty of threads about that around here.

I use:


sudo reboot

This command can be used in a shell script provided the script is being run as root.
