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.
ffi 1.0 or later
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)
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
Users on SunOS get several extra methods:
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
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
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
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as a nicer way to check simple information about your system, and as a replacement for the old 'Platform' gem which is no longer maintained.
I may dump the "Uname" portion of this library, and rename the project to just sys-platform.
For more details, see the 'uname.rdoc' file under the 'doc' directory.
