Shutdown

[Guest mahiles]

Is there anyway I could create a file that, when executed does "su" and enters the root password and then shuts down the computer?

 

Getting even more complicated (especially for newbie me lol) could I get it to prompt me if I wanted to enter a delay time?

 

Slightly separate question but same topic, whats the difference between doing "shutdown -h..." and skipping the -h. I know it means halt but what does that actually do? Doesn't seem to make any difference to me?

 

Thanks

I can type shutdown or reboot as any user. Is it different on your system? If so, you might want to investigate sudo which allows you to assign root prives to specific users for specific actions.

I can only do shutdown with root however can do reboot with any user. How do I do that second part?

how bout the halt command as any user ??? You should be able to shut down from whatever user you are at the time.

Halt works with any user but I can't see any way of setting a delay using that?

You can't set a delay with the halt command. You can use shutdown with a delay.

 

shutdown -h -t5

 

That will shut your machine down in 5 seconds. The -t option must be in seconds.

If you need halt, use sleep

 

sleep 5; halt

 

will make the halt command wait 5 sec before executing. You can also specify minutes, hours, and days :shock: :lol:

 

sleep --help

man sleep

info sleep
