Counting characters with unix utilities

[Mike My Watch Has Windows Meyer]

   ed must have been kidding when he left the cat in place, instead of

   tr -cd 'A' < file | wc -c

Why? Some people prefer the form

	cat file | utility args

to

	utility args < file

Why change from one to the other, except for efficiency? And even
then, there isn't enough difference to bother with for a command line.
For a script, you'd want to use the latter, though. But then the
difference is hidden from the user.
