Perhaps.  But the command to execute would be relatively arbitrary.
What I'm trying to do is set up a script that will filter the results
of a grep.  But what I'm grepping and where I'm starting from would
change.  I suppose I could pass those arguments to my script and
access it using argv but I'm actually kind of curious how (if) I can
access output which has been piped (or redirected) to my script.
