How do I find out what the name of my CD-ROM or DVD device is under Linux operating system without using GUI options?

You can type the following command to see current information about installed and detected CDROM or DVD-writers under Linux operating systems. The dmesg command can be used to check if given hardware or device was identified correctly by the Linux kernel.

dmesg Command

dmesg command is used to examine the Linux kernel ring buffer i.e. display bootup messages on screen. To find out if cdrom was detected or not, run:
$ dmesg | egrep -i --color 'cdrom|dvd|cd/rw|writer'
Sample outputs:

[    5.437164] sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray
[    5.437307] cdrom: Uniform CD-ROM driver Revision: 3.20

In this output sr0 is my cdrom / dvd reader and writer. You can see more detailed information by typing the following command
$ less /proc/sys/dev/cdrom/info
OR
$ more /proc/sys/dev/cdrom/info
Sample outputs:

grep should not be case sensitive. I have my cdrom drive in CAPS

# dmesg |egrep -i ‘cdrom|dvd|cd/rw|writer’
hdc: VMware Virtual IDE CDROM Drive, ATAPI CD/DVD-ROM drive

If the /proc/sys/dev/cdrom/info output shows:
Can close tray: 1

What command will close the tray and do any specific packages need to be installed to do so?
