I'm done here!
 

What is your preferred command for shutting down the system? Please explain your votes.

I never use sudo, only su and sometimes su -
shutdown -H now fills the bill.

Ctrl-Alt-Del which runs 'shutdown -h now'. No, I don't use sudo.

that's not a common behavior.. ctrl + Alt + Del on most distro's executes "shutdown -r now", not "-h".

shutdown -h now, if I'm in runlevel 3.
KDE main menu -> Leave -> Shutdown, if I'm in runlevel 4.

I just press the power button on the front of my case. ACPI does the rest.

Yes, I changed it in inittab. I rarely need to restart.

Changed the /etc/inittab and ctrl+alt+del powers the pc off.

shutdown -h if I am trying to impress someone otherwise just the powerbutton.

Good answer. :)

I remember using "park".

My power button is under a panel, and is hard to reach, that's why I use Ctrl-Alt-Del. This combo also exits fluxbox.

sudo??

I use ctrl-alt-del most of the time.

Inittab entry is changed to: ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -h now, besides root, only 1 other user has the power to shut down the system.

@mlangdn: park, I remember that command too!!
