Description

The sys-uname library is a Ruby interface for getting operating system information. The name comes from the Unix ‘uname’ command, but this library works on MS Windows as well.

Installation

gem install sys-uname

If you’re on MS Windows, and the above doesn’t work try:

gem install sys-uname --platform universal-mingw32

Synopsis

require 'sys/uname'
include Sys

p Uname.uname # => Display everything

puts Uname.sysname  # => The operating system name. e.g. "SunOS"
puts Uname.nodename # => This is usually, but not necessarily, the same as the system's hostname.
puts Uname.machine  # => The machine hardware type. e.g. "i686"
puts Uname.version  # => The operating system version. e.g. "5.8". Windows includes patch information.
