Hi,

You can give halt and reboot SUID permissions with (as root):

Code:

chmod u+s /sbin/halt
chmod u+s /sbin/reboot

Then you can type /sbin/halt as any user

You can also use SUDO:
From http://www.userlocal.com/phorum/read...15442&t=15435:

Quote:

as root run visudo

this will open the /etc/sudoers file in the vi editor (Make sure you know how to use vi before opening that file

simply add the following line...

%users darkstar = /sbin/halt, /sbin/reboot
(replace "darkstar" with the hostname of your machine)

Now any user may issue sudo /sbin/halt to shut down the system
if you don't want to have to type a password each time then use this line

%users darkstar = NOPASSWD: /sbin/halt, /sbin/reboot

Now to me you seem like a lazy SOB so you probably don't want to type all that sudo stuff etc..

You can just create an alias for it ... simply add these to lines to your ~/.bash_profile (create this file if it doesn't exist)

alias halt='sudo /sbin/halt'
alias reboot='sudo /sbin/reboot'

HTH, Taj

I think so. I tried to edit it in emacs, it didn't work. You've gotta use visudo...I guess. Donno why.

AAWR

You can edit the file with any editor. You will not damage the file.

If you don't like vi, you can try pico. Just type pico filename

Good luck
