When you do the EXPORT you should be able to launch software installed with
Guix by just typing "program" you installed hello so just type
$ hello
It should run.
If you puth the export in your PATH you should be able to do this and
probably see the icons of the programs on the menu of your Desktop
Environment (I am not sure about this is I don't use menus only I3wm with
dmenu)
The path should be ~/.bash_profile but I don't remember exactly to be honest.
Maybe someone can help us or you can ask for a little wore help on #guix on
IRC they are friendly and helpful.
If you use IRC make sure to join #lgn :) I am there most of the time. Is a
great channel
