[Newbies] FFI versus BASH

I have a question that I imagine is going to reveal a big gap in my
knowledge. Oh well.
I have a framework such as QuickTime that I want to send a message to.
In Sophie I can execute some code in a Workspace and it will go to the
FFI, send a message to the QT framework, and then return. But I can't do
that in BASH.
To send a message to the library, I'd need to write a text file,
compile, and then execute. Then the response comes back into the
Terminal. Why can't I just enter Carbon functions in the shell and do
what Workspace/FFI does?
Or, does FFI compile on the fly and then de-compile to put an answer in
The real question here, I think, is what is a message in Linux? Is it a
stream of bits with meta data?
A message is being sent to the library, but I don't grok what that
message is. Any help would be greatly appreciated,
