在/usr/share/applications和/usr/share/app-install/desktop寻找需要的图标,没有就自己做一个

eclipse的图标

[Desktop Entry]

Version=1.0

Name=eclipse

Exec=/home/common/software/eclipse/eclipse

Terminal=false

Icon=/home/common/software/eclipse/eclipse.png

Type=Application

Categories=Development

 sublimetext的图标

为了使得sublime能修改root的文件,安装gksu,然后在Exec前面加上gksu

[Desktop Entry]
Name=SublimeText2
Type=Application
Terminal=false
Comment=Edit text files
Exec=/home/common/software/SublimeText2/sublime_text %F
Icon=/home/common/software/SublimeText2/sublime_text.png

 注意末尾不要有空格

 docky添加的图标的目录在

~/.local/share/applications
