You don't have to cut-n-paste into a new notebook cell -- just edit the 
cell in place and re-evaluate it (hit shift-enter anywhere within the 

Probably that's all you needed to know, but...

It sounds like the equivalent of what you describe in Octave could be done
with the mathematica function Get.  If you have a file stuff.m with
mathematica code and enter Get["stuff.m"] in a mathematica session, it
will evaluate the contents of the file as if you had entered it all in
right there.

If you really want mathematica to act like a real programming language
(handle command line args, process stdin and stdout, etc) then check out
MASH (for Mathematica Scripting Hack) at
