Open the CD tray using Terminal

This might come pretty hand, once I get my beloved Happy Hacking Keyboard because, unlike the Mac Pro Keyboard, the Happy Hacking does not have a dedicated key to open/ close the CD tray on the Quicksilver.

Open Terminal, and execute:

drutil list

On my case I have only 1 CD ROM unit:

% drutil list
   Vendor   Product           Rev   Bus       SupportLevel
1  SONY     DVD RW DRU-700A   VY02  ATAPI     Vendor Supported

Then, to open the tray, you can type:

drutil tray eject 1

If like me, you only have 1 CD ROM installed, you directly type:

drutil tray eject

There is more information for drutil on its man page, a little snip:

     tray command
                Performs a tray/media related command. Note that some drives
                do not have trays, and some have trays but may lack motorized
                eject or inject capability.

                Tray commands:
                open     Opens a drive's tray, if no media is present and the
                         drive has a tray capable of motorized eject.

                close    Closes a drive's tray, if the drive has a tray capa-
                         ble of motorized inject.

                eject    Ejects media from the drive, if the drive has a tray
                         capable of motorized eject. If no media is present,
                         this is equivalent to open.  If media is present and
                         can be unmounted, it will be unmounted and then
                         ejected.  If media is present but cannot be
                         unmounted, the eject will fail.
