Ruby

Description

A cross-platform 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

Adding the trusted cert

gem cert --add <(curl -Ls https://raw.githubusercontent.com/djberg96/sys-uname/main/certs/djberg96_pub.pem)

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
  • dhcp_cache

Note that Solaris is essentially a dead OS at this point, so it will not be supported going forward, and will likely be dropped in the next major release.

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as a nicer way to check simple information about your system, and as a replacement for the old 'Platform' gem which is no longer maintained.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.
