Hi,
  I posted 3 questions about shells, what actuall I meant for 3) is that
: I would like to make an alias (not shell script) that can be invoked
in either way as :
		i) upcase arg1 [arg2 ... arg N], as well as
        ii) filterprogram | upcase.
But I will like is to achieve ii) without pipeline.

  That is, the alias has to figure out if it is going to read its command 
line argument (if they exist) or from its stdin (if command line args
don't exist).

  Many thanks in advance. Also I would really like to hear from some of
the Unix gurus for the first 2 questions as I haven't got any (correct)
replies yet.
