I have nginx log file, and I want to find out market share for each major version of browsers. I am not interested in minor versions and operating systems. I would like to get something like this:
100 IE6 99 IE7 20 IE8 200 FF2 300 FF3
I know how to get the list of user agents from the file, but I want to aggregate the list to see only the major versions of the browsers. Is there a tool that does it?
