I've noticed that each DVD image has a semi-unique uppercase name. Is there a standardized way for me to simply read this name as a non-root user in Linux? I'm on an Ubuntu 12.04 derivative running kernel 3.7. I'd like to simply get the name of any disk currently in the drive like so:DVD_NAME=$( ./read-dvd-name.sh )
Read the title from a DVD?
bash;dvd
You could  use blkid for that:DVD_NAME=$(blkid -o value -s LABEL /dev/dvd)(you need to have read permission to /dev/dvd for that).Or:DVD_NAME=$(udevadm info -n dvd -q property | sed -n 's/^ID_FS_LABEL=//p')for which you don't need any special privilege (udev (running as root) queries the label name using blkid and updates a device database which you query with udevadm).
