I have several utility programs that I can run only by clicking on their "generic" executable file. How can I assign an icon to each of them for it to show in the Launcher? I am using Ubuntu 14.04 LTS. Thanks.
Create a "Application_name.desktop" file using gedit or any other text editor with contents
put it in ~/.local/share/applications
