  • Sounds like premature optimization... 5MB is not a lot, whether it be working memory or storage size. – Brendan Lesniak Dec 30 '14 at 18:32
  • Have you tried using compression options which are already in java such as gzip or any of options in the apache commons-compress library? http://docs.oracle.com/javase/8/docs/api/java/util/zip/GZIPOutputStream.html http://commons.apache.org/proper/commons-compress/ – Brett Okken Dec 30 '14 at 18:35

  • You couldnt have possibly googled for the answer to this question because it is a very easy answer to find if you actually did google for it. This is a duplicate; thanks Colin D. – searchengine27 Dec 30 '14 at 18:39

What you want to do should be able to be achieved by simply running a bash script, which is pretty simple. Also it happens that someone has asked that question before so that answer should in turn answer yours. Please let me know if you want a more detailed response or need help with the implementation.
