How to process bigger gzipped files with Ruby 1.8

Question

是否可以使用有限的RAM使用纯Ruby（1.8）处理巨大的文件（〜3G）？

Answer 1

是的，您可以使用Zlib :: GzipReader通过#each_line或#each_byte逐行处理它。

Answer 2

I guess the following would make sense:

 Zlib::GzipReader.open(file) { |gz|
   gz.each_line { |line|
     #do stuff
   }
   gz.close
 }

Let me know if you have a better solution.
