That question doesn't really make sense.  A pipe provides a method to 
transfer a stream of bytes.  You could indeed send that byte across the 
pipe, but it's just a byte, written by one process and read by another 
process.  The receiving process can examine the byte stream, and do 
whatever it wants in response.

By calling it a _command_, you seem to expect some particular behavior 
out of the receiving process.  Please tell us *what* that might be, and 
we'll see what we can do to help out.
