Ubuntu添加Intellij IDEA啓動器

1. 建立/usr/share/applications/idea.desktop文件。

2. idea.desktop文件內容以下：

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Name=IntelliJ IDEA
GenericName=Java IDE
Comment=IntelliJ IDEA is a code-centric IDE focused on developer    productivity. The editor deeply understands your code and knows its way around the codebase, makes great suggestions right when you need them, and is always ready to help you shape your code.
Exec=/usr/local/lib/idea/bin/idea.sh
Icon=/usr/local/lib/idea/bin/idea.png
Terminal=false
Type=Application
Categories=Development;IDE

3. 更復雜的例子能夠參照目錄/usr/share/applications/下的其餘desktop文件。
