Read a file in chunks in Ruby

Question

I need to read a file in MB chunks, is there a cleaner way to do this in Ruby:

FILENAME=\"d:\\\\tmp\\\\file.bin\"
MEGABYTE = 1024*1024
size = File.size(FILEN         


        

Answer 1

You can use IO#each(sep, limit), and set sep to nil or empty string, for example:

chunk_size = 1024
File.open('/path/to/file.txt').each(nil, chunk_size) do |chunk|
  puts chunk
end
