eject [options] [device]
Eject removable media such as a CD-ROM, floppy, tape, or JAZ or ZIP disk. You may name the device by its /dev or /mnt filename. The /dev and /mnt prefixes are optional for any items in the /dev and /mnt directories. If no device is named, it is assumed that "cdrom" should be ejected.

Set the auto-eject mode to on or off (equivalent to 1 or 0, respectively). If auto-eject mode is on, the device is ejected when closed or unmounted.
If using a CD-ROM changer, select a CD from one of the slots. Slots are enumerated starting with 0, and the CD-ROM drive must not be playing music or mounted to read data.
