Little-known options for the OS X login window

If you have your login window set to show the Name and Password fields (as opposed to the "List of users" or auto-login), you will see a window like the one shown above when your Mac first boots, when you logout, or when you change to the login window if you have Fast User Switching enabled.
OS X has supported several "special" login names for a long time. Each is entered into the "Name" field with no password. They are:
>restart
>shutdown
>sleep
>console
You can probably guess what the first three do. The fourth one ">console" will drop you to a shell login prompt, where you can login with your username and password if you want quick access to a shell instead of the full user interface. The restart/shutdown/sleep buttons will only work if you have not turned off to option to show them, but ">console" works regardless of that setting.
The upshot of these settings: if you somehow found yourself using a version of OS X which lacked a "Restart" button on the login window, you could login as ">restart" in order to reboot your Mac.
You can also easily add your contact information to the login screen (as shown above).

N'mind. I downloaded OnyX & tried using it. With it, unlike MacPilot, 'Option-Return' successfully added line breaks to my login welcome message...
There's also >exit
In the NeXT days, that caused the WindowServer to restart. Something similar seems to happen now, but given the rearchitecting of the windowing system since the Display Postscript days, it may not have quite the same effect.
and wheres the way to disable such nonsense?
huge security fail.
Here's what the problem was: both user accounts had the same password. Changing the admin password let me log into the system at the console.

Even if you don't have the "show name and password" mode, you can still press cmd+option+up-arrow+return to force those fields to be shown. This only works if you have more than one user on your mac.

Its a few less keys and works regardless of how many users there are. Useful if theres a hidden admin account.

I was trying to enter the personal info as shown above through OnyX but i cannot get it to show the same way, instead is shown all as a long sentence.
Any ideas?
Thank you!
The area code/first 3 digits of your phone number tells me TJ Luoma is a Gallipolis Ohio man?? That's not too far from me! Sweet!
