本文介绍如何在面板上添加一个图标，通过点击它即可卸载和弹出CDROM.
步骤：
创建一个新文件
gksudo gedit /usr/local/bin/eject_cd
粘贴如下代码
<nowike>
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
</nowiki>
给该文件加上可执行属性:
sudo chmod +x /usr/local/bin/eject_cd
在桌面面板创建一个启动器（或其他你喜欢地方）
Right-click on the panel 'Add to Panel' 'Custom Application Launcher'
在右键点击桌面面板 ‘添加到面板’ ‘用户自定义应用程序’
输入信息（根据你实际的CDROM设备路径，替换 /dev/cdrom）
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
名字： 弹出CDROM 备注：卸载，弹出CDROM 命令：/usr/local/bin/eject_cd -z /dev/cdrom 图标：/usr/share/icons/gnome/24x24/devices/gnome-dev-removable.png
点击‘关闭’
注：这个脚本调用了zentity来提示错误，如果你不想要这个功能，那么删除 ‘-z’这个参数。
安装zenity：
sudo apt-get install zenity
