How to create a launcher for a manually extracted program in Ubuntu

Say we have a latest Blender extracted from the download package. We want to create a launcher for Blender so that we can start it from the Unity Dash or App Menu.

Press Ctrl+Alt+T to open terminal. When it opens, run command to create .desktop file and edit it with Gedit text editor:

sudo gedit /usr/share/applications/blender-2.7.desktop

When the file opens, paste below into it and save.

[Desktop Entry]
