   ed must have been kidding when he left the cat in place, instead of
   tr -cd 'A' < file | wc -c

nope.  I cat files all the time.  That way when I go back to edit this command
to work on the output of a command instead of the contents of a file
there's no extra work or thinking involved.

      grep ^Subject file | tr -cd 'A' | wc -c
