Hmm, that's strange. if run as 'count.bat <somefile' or 'cat 
somefile|count.bat' it works, but I get a similar error 'ruby: No Ruby 
script found in input (LoadError)' when run as you did. I haven't seen 
this behavior before, and don't know a way around it except to use the 
forms I showed that do work. :(
