some people are marking this question as duplicate of some other question(which are I looked up, not helpful. since it is just explainig how to use unity, not technical/command line documentation) which is not right
I want to learn how unity works. for example, instead of dragging application shortcut from dash to launcher, how do I do it using terminal?
how to make application shortcut ?
I can lock an application to the launcher by GUI but how to do it from terminal?
How an I add a mounted partition icon automatically if I mount it from a folder other than /media
?
these are just examples, I dont meant just to learn these but unity all-together
