I'm pretty sure Bash is turing complete.  I know it's been shown that
sed is turing complete, and awk probably is too!  If I recall, the way
to show a language is turing complete is to implement a turing machine
in it.  I'm pretty sure bash could handle that, though maybe with help
from a standard set of unix tools one always finds used in conjunction
with the shell.  Here's one implementation:

I would say that "scripting language" isn't a definition of a type of
language, but rather a description of how a language is put to use in a
particular case.  For example, when embedded in a game, lua is used as a
scripting language to automate and extend the game in certain ways, by
exposing game objects to the lua engine and allowing interpreted lua
code to manipulate (script) them.  Javascript is the same thing in other
programs.  But whether you call javascript a scripting language in
firefox, or something much more (as it's actualy required for firefox to
function at all), is a matter of personal preference really.

I've seen python embedded in apps to act as a scripting language before.
 I've also seen full-blown apps written in python.

So yes, the distinction, as made by the original poster, isn't really
necessary.
