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:
CD-ROM information, Id: cdrom.c 3.20 2003/12/17 drive name: sr0 drive speed: 24 drive # of slots: 1 Can close tray: 1 Can open tray: 1 Can lock tray: 1 Can change speed: 1 Can select disk: 0 Can read multisession: 1 Can read MCN: 1 Reports media changed: 1 Can play audio: 1 Can write CD-R: 1 Can write CD-RW: 1 Can read DVD: 1 Can write DVD-R: 1 Can write DVD-RAM: 1 Can read MRW: 1 Can write MRW: 1 Can write RAM: 1
To see CD-ROM drive characteristics information, enter:
$ cd-drive
Sample outputs:

Hi,
How can we remove many “Profile List Feature” without any other external command ?
thanks a lot
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?
