You will get an icon on your panel and when you click on it, the cdrom gets unmounted and ejected.
Create a new file:
gksudo gedit /usr/local/bin/eject_cd
Paste the following lines:
DEVICE="$1" ZENITY_BIN="/usr/bin/zenity" trap ctrlc INT ctrlc() { echo -e "\nAborted by user." rm -rf $TMP_DIR exit 2 } show_dialog() { if [ "$use_zenity" -gt "0" ] ; then zenity --error --title "CD-Rom eject" --info-text "$1" fi } if [ "$1" === "-h" ] || [ "$1" === "--help" ] ; then echo "Usage: eject_cdrom [-q] DEVICE" echo -e "Try to unmount DEVICE then eject it if successful.\n" echo "Possible parameters:" echo -e "-h, --help\tdisplay this help and exit." echo -e "-z, --zenity\tuse zenity to displays errors in dialog windows." exit 0 fi if [ "$1" === "-z" ] || [ "$1" === "--zenity" ] ; then if [ ! -x "$ZENITY_BIN" ] ; then echo "You must install zenity before that." exit 1 fi use_zenity="1" device="$2" else use_zenity="0" device="$1" fi if [ ! -e "$device" ] ; then echo "Parameter DEVICE is not a file." exit 1 fi echo "Trying to eject CD-Rom..." umount "$device" 2>/dev/null last_err="$?" if [ "$last_err" -eq "1" ] ; then msg="Cannot unmount device $device (busy)." echo "$msg" show_dialog "$msg" exit 1 fi eject "$device" last_err="$?" if [ "$last_err" -ne "0" ] ; then msg="Cannot eject device." echo "$msg" show_dialog "$msg" exit 1 fi exit 0
Make the script executable:
sudo chmod +x /usr/local/bin/eject_cd
Create a new launcher on a panel (or wherever you want):
Right-click on the panel 'Add to Panel' 'Custom Application Launcher'
Type this (replace /dev/cdrom with your CD-Rom device):
Name: Eject CD-Rom Comment: Unmount and eject the CD-Rom /dev/cdrom Command: /usr/local/bin/eject_cd -z /dev/cdrom Icon: /usr/share/icons/gnome/24x24/devices/gnome-dev-removable.png
Click 'Close'
Note: This script uses zenity to display errors. However if you don't want this feature, remove the '-z' parameter.
To install zenity:
sudo apt-get install zenity
