Count bytes

file = File.new("myfile")
e_count = 0
file.each_byte do |byte|
  e_count += 1 if byte == ?e
end



each_byte is always associated with a block.

file5 = File.new("C:\\Ruby\\Sample")
file5.each_byte{|ch| putc ch}



read an I/O stream byte by byte with each_byte:

File.open("text.txt").each_byte { |byte| puts byte }
