It should be noted that shell programming is closely related to functional
programming.
I.E. functional programming maintains no external state and provides
data flow synchronisation in the language. This maps closely to the
UNIX filter idea; data flows in and out, with no side affects to the system.
By trying to use filters and pipes instead of procedural shell statements,
you get the advantage of using compiled code, and implicit multicore support
etc.
