The typical "useless use of cat" often is just an illustration
of how to use a certain command within a pipe chain. In cases
where no piping is needed, redirection can be used easily.

	% cat food.txt | grep "catfood" > mister_kitty.txt

Or:

	% grep "catfood" < food.txt > mister_kitty.txt

I hope the cat will understand now. =^_^=
