I am running Debian 9 (stretch) and XFCE. I am creating a desktop file so I can launch Mozilla Thunderbird from the Whisker menu. I would like Thunderbird to have the right value for its
Categories attribute. I generated a list of categories using the following command. An example of the command's output also follows.
cd /usr/share/applications grep -i -P -e "^[Cc]ategories[=].*" ./*.desktop | sort | uniq
However, the list I generated might not be complete. I have read other questions including:
- How do I create an Xfce application menu containing only the contents of one category?
- Add icons/menu items for applications in XFCE
- Empty XFCE Applications menu
Where can I find a complete and canonical list of categories?
Here is the desktop file I created.
