Ubuntu的快捷方式文件.desktop说明

.desktop file.  “There was an error lunching the application”

参考别人的旧文件写的 my-app.desktop

双击的时候一直提示上面错误，在ubuntu论坛上找到解决办法：

（https://askubuntu.com/questions/496367/desktop-file-running-sh-script-there-was-an-error-launching-the-application/836842#836842）

desktop-file-validate your-file-here.desktop

“ This was the hidden command I was trying to find since hours. This, Saved my day :-)

This command will show you warning and errors wherever you have gone wrong.Credits : ubuntuforums ”

执行此命令，终端提示：

 

$ desktop-file-validate Pycharm.desktopPycharm.desktop: warning: key "Encoding" in group "Desktop Entry" is deprecated
Pycharm.desktop: warning: value "Application;Programme;" for key "Categories" in group "Desktop Entry" contains a deprecated value "Application"
Pycharm.desktop: error: value "Application;Programme;" for key "Categories" in group "Desktop Entry" contains an unregistered value "Programme"; values extending the format should start with "X-"
Pycharm.desktop: hint: value "Application;Programme;" for key "Categories" in group "Desktop Entry" does not contain a registered main category; application might only show up in a "catch-all" section of the application menu

根据提示，修改.desktop文件（去掉.desktop文件的Categories的value“Programme”, "Application"改成“X-Application”，Ok）

成功的.desktop文件如下：

快捷方式图标的存放位置: /usr/share/applications 。将.desktop 文件移到该目录下。
