| |
| | |
| 创建一个新文件：
| |
| <pre><nowiki>
| |
| sudo gedit /usr/local/bin/eject_cd
| |
| </nowiki></pre>
| |
| | |
| Paste the following lines:

| # Try to unmount a CD-Rom device, then eject it.

| </nowiki></pre>
| |
| | |
| Make the script executable:
| |
| | |
| 把该脚本设为可执行：
| |
| <pre><nowiki>
| |
| sudo chmod +x /usr/local/bin/eject_cd
| |
| </nowiki></pre>
| |
| | |
| Create a new launcher on a panel (or wherever you want):
| |
| | |
| 在面板上（或其它你喜欢的地方）创建一个新的启动器：
| |
| <pre><nowiki>
| |
| Right-click on the panel
| |
| 'Add to Panel'
| |
| 'Custom Application Launcher'
| |
| </nowiki></pre>
| |
| | |
| Type this (replace /dev/cdrom with your CD-Rom device):
| |
| | |
| 输入下列内容（用你的CD-Rom设备替代/dev/cdrom）：
| |
| <pre><nowiki>
| |
| 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
| |
| </nowiki></pre>
| |
| | |
| Click 'Close'
| |
| | |
| 单击'Close'（关闭）
| |
| | |
| Note:
| |
| This script uses zenity to display errors. However if you don't want this feature, remove the '-z' parameter.
| |
| | |
| To install zenity:
| |
| | |
| 注：这个脚本使用zenity来显示错误信息。当然如果你不需要该特性，只需移除'-z'参数。
| |
| | |
| 如下命令可安装zenity：
| |
| | |
| | |
| <pre><nowiki>
| |
| sudo apt-get install zenity
| |
| </nowiki></pre>
