The sys-uname library provides an interface for gathering information about your current platform. The library is named after the Unix 'uname' command but also works on MS Windows. Available information includes OS name, OS version, system name and so on. Additional information is available for certain platforms.
gem install sys-uname -v 1.0.3
= Description 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. = Prerequisites ffi 1.0 or later = Installation gem install sys-uname = Synopsis require 'sys/uname' # require 'sys-uname' works, too # You now have Sys::Uname and Sys::Platform classes available. # Get full information about your system p Sys::Uname.uname # Check individual platform details about your system p Sys::Platform.linux? # => true p Sys::Platform::ARCH # => :x86_64 = Solaris Notes Users on SunOS get several extra methods: architecture, platform, hw_serial, hw_provider, srpc_domain, isa_list, and dhcp_cache. = BSD flavors, including OS X Users on BSD platforms get the extra Uname.model method. = HP-UX Notes HP-UX users get the extra Uname.id_number method. This is actually a String, not a Fixnum, because that's how it's defined in the utsname struct. = MS Windows Notes The C version for Windows has been completely scrapped in favor of an OLE plus WMI approach. It is pure Ruby. Please see the MSDN documentation for the Win32_OperatingSystem class for a complete list of what each of the UnameStruct members mean. = The Platform Class This was added both as a nicer way to check simple information about your system, and as a replacement for the old 'Platform' gem which is no longer maintained. = Future Plans I may dump the "Uname" portion of this library, and rename the project to just sys-platform. = Documentation For more details, see the 'uname.txt' file under the 'doc' directory.
