everyday chemistry - What is smell??How come 2 things have the same smell



I have been wondering how something smells.

How come something smells the same as other thing? What is similar in them?
Like what is the chemistry behind a particular smell of a substance?




For example compounds with SH (thiol) smell awful and similar, so what is similar between them? I know SH, but I am asking why can't they smell different.
