Short cut shutdown

targettl · 11-06-2009, 12:51 AM

I know that there is a short cut to reboot a machine, which is:
control,alt,delete.

Is there a universal equivalent that will shut down a machine. I am not talking about from the actual OS but when I am loading grub or something like that.

/etc/inittab

this line will keep shutting down your system.
you never want to do this becuase this will lock you out of system.

#HALT (SHUTDOWN)
id:0:initdefault:

#your system will keep restarting . you will not get chance to do any #login.
id:6:initdefault:

#shutdown -h now : to shutdown your system

#reboot : to reboot
#shutdown -r now

It seems you are asking a question about the bios. As far as I know there is no "universal equivalent" to shut down machines implemented in all bios'.

What happens when you press Ctrl-Alt-Del is defined in /etc/inittab as stated eariler.

By default it is:

Code:

# What to do at the "Three Finger Salute".
ca::ctrlaltdel:/sbin/shutdown -r now

if you want it to shutdown instead you would change that to:

Code:

# What to do at the "Three Finger Salute".
ca::ctrlaltdel:/sbin/shutdown -h now

The settings are applied next reboot.

It would be nice to have a universal shortcut in all bios's but this doesn't seem to be the case. Maybe Shift,Control,Delete would be a good idea.

By the way this isn't really a Linux question, but this is the best forum site around so I thought I would put it here anyways.
