How to eject CD using the terminal?

Question

I recently found a question on superuser regarding ejecting a CD using the Windows command line.

How can I do this using Linux terminal?

@muru wouldn't I need to specify exactly what I want to eject, in order to prevent the system from ejecting every external device? — TellMeWhy, Sep 14 '15 at 17:14
If you could take a few minutes to read the manpage I linked to, you'd see: " The device corresponding to is ejected. The name can be a device file or mount point, either a full path or with the leading "/dev", "/media" or "/mnt" omitted. If no name is specified, the default name "cdrom" is used." — muru, Sep 14 '15 at 17:15
and then after you eject it (if it can pull itself back in) you can use eject -t... — Gophyr, Sep 14 '15 at 17:17

The eject command does what you want. Without any arguments provided, it ejects the default (first) 'cdrom' device. If you want to eject a specific device, provide it as an argument.

eject /dev/cdrom1

Quoting from the eject manpage (man eject):

Eject allows removable media (typically a CD-ROM, floppy disk, tape, or JAZ or ZIP disk) to be ejected under software control. The command can also control some multi-disc CD-ROM changers, the auto-eject feature supported by some devices, and close the disc tray of some CD-ROM drives.
The device corresponding to is ejected. The name can be a device file or mount point, either a full path or with the leading "/dev", "/media" or "/mnt" omitted. If no name is specified, the default name "cdrom" is used.

And to close it (if the drive supports it), eject -t – kos Sep 14 '15 at 17:19 — kos, Sep 14 '15 at 17:19
