FWIW, I got the raw numbers to do my quick check using this Ruby
script (put together for me by Peter Brant). If it is of any use to
anyone else, feel free to use it and/or post any enhanced versions
of it.
#!/usr/bin/env ruby
Dir.glob("*") do |file_name| contents = File.read(file_name) total =
contents.enum_for(:each_byte).enum_for(:each_slice,
256).inject(0) do |count, chunk| if chunk.all? { |b| b == 0x55 } count + 1 else count end end
printf"%s %d\n", file_name, total
end
