it seems to be a common misunderstanding these days.

i think a lot of "old-timers" (i.e. people who have been working with
unix for 5-10 years or more) think about computers in a "data-centric"
conceptual model - i.e. where data can come from, how it can be
transformed, and where it can be sent to. this is pretty fundamental to
the "unix way" of doing things.

newcomers often don't have this conceptual model, so solutions that
seem self-evidently obvious to old-timers don't even occur to them.

i run into this all the time, and one of the real joys about teaching
someone unix is to see the light of understanding when i finally get
this concept across...i managed to achieve this yesterday with one of my
junior sysadmins at work, which is why i'm thinking about it.

so, does anyone know of any web sites or books that present a tutorial
about this - explaining the theory as well as providing practical
examples?

ps: by contrast, windows programmers learn a user­interface centric
model - everything is focussed around the user interface, the actual
data is almost irrelevant. this is one of the major reasons why it's so
difficult to reuse data in the windows world. unlearning this is one of
the hardest things for a windows programmer when they move to unix.
