Thanks for the replies, everyone.  I wound up with

def do_substitution( filename )
  File.open("#{filename}.tmp", "w") do |ofile|
    File.open("#{filename}") do |file|
      file.each do |line|
        yield ofile, line
      end
    end
  end
  File.rename("#{filename}.tmp", "#{filename}")
end

Which is probably overkill for my needs, but got me learning about
blocks and is flexible.  And fun!

Thanks again.

Art
