A quick google search led to this: [http://snippets.dzone.com/posts/show/6238](http://snippets.dzone.com/posts/show/6238) I imagine using RUBY\_PLATFORM in some manner is a good solution. ---

It’s easiest with [GitHub - rdp/os: The OS gem allows for some easy telling if you’re on windows or not. OS.windows? as well as some other helper utilities](http://github.com/rdp/os) ---

No, do not use RUBY\_PLATFORM. JRuby will return “java”, for example: If you want something built in use rbconfig.rb. Specifically, Config::CONFIG[‘host\_os’]. Or you can use a 3rd party gem like sys- uname or os. Regards, Dan
