    Perhaps this does what you want, it uses Config which is core. Tested on Windows, Solaris and netbsd:

    #!/usr/bin/perl use strict; use warnings; use Config; print "$Config{osname}\n"; print "$Config{archname}\n"; print "$Config{osvers}\n";

    Output:

    MSWin32 MSWin32-x86-multi-thread 5.1

      Thanks.... One another way to get specially for windows is

      my $osname = Win32::GetOSName(); my ( $osvername, $major, $minor, $id ) = Win32::GetOSVersion(); print "osname: $osname\n"; print "osvername: $osvername\n"; print "major: $major\n"; print "minor: $minor\n"; print "id: $id\n";

        True, though you didn't specify which OS you were using when you posted the question ;)

        Update: I see you've just changed your question to specify OS. It'd make more sense if you'd posted that as an update to your post, like I've done here.

    You can use Win32 to get the information you want then a little playing around to get a OS name:

    #!/usr/bin/perl use warnings; use strict; use Win32; my %versions = ( 0 => {'' => {'' => "Win32s"}}, 1 => { 4 => { 0 => "Windows 95", 10 => "Windows 98", 90 => "Windows Me" } }, 2 => { 3 => {51 => "Windows NT 3.51"}, 4 => {0 => "Windows NT 4"}, 5 => { 0 => "Windows 2000", 1 => "Windows XP", 2 => "Windows Server 2003" }, 6 => { 0 => "Windows Vista or Server 2008", 1 => "Windows 7" } }, ); my ($name, $major, $minor, $build, $id) = Win32::GetOSVersion(); print $versions{$id}{$major}{$minor};

    Actually a little more work than that is required to do a proper job, but it is well documented in Win32::GetOSVersion() docs linked above.

    True laziness is hard work

    Hi All,
    I am trying to see if the Windows version I am using is newer than Windows 7 or Windows Server 2008 R2 (minimum requirements). I googled a bit and run into your post. Here is my question, I am running on Windows 10 machine and these lines:

    print ("(\$ENV{\"OS\"}: " . ($ENV{"OS"}) . "\n"); use Win32; print "GetOSName: " . Win32::GetOSName() . "\n"; use Config; print "$Config{osname}\n"; print "$Config{archname}\n"; print "$Config{osvers}\n"; my ($name, $major, $minor, $build, $id) = Win32::GetOSVersion(); my %versions = ( 0 => {'' => {'' => "Win32s"}}, 1 => { 4 => { 0 => "Windows 95", 10 => "Windows 98", 90 => "Windows Me" } }, 2 => { 3 => {51 => "Windows NT 3.51"}, 4 => {0 => "Windows NT 4"}, 5 => { 0 => "Windows 2000", 1 => "Windows XP", 2 => "Windows Server 2003" }, 6 => { 0 => "Windows Vista or Server 2008", 1 => "Windows 7" } }, ); print "version: " . $id . ", " . $major . "," . $minor . "\n";
    yields me:
    ($ENV{"OS"}: Windows_NT GetOSName: Win2003 MSWin32 MSWin32-x86-multi-thread 4.0 version: 2, 6,2
    My questions are:
    1) How can I see it is windows 10? Why do I receive "Windows_NT" and "Windows2003" in my first two lines?
    2) @marto why do I get the version to be 4.0?
    3) @GrandFather, I looked into the link you posted http://search.cpan.org/~jdb/Win32-0.52/Win32.pm, but all I see there is a table of:
    OS ID MAJOR MINOR Win32s 0 - - Windows 95 1 4 0 Windows 98 1 4 10 Windows Me 1 4 90 Windows NT 3.51 2 3 51 Windows NT 4 2 4 0 Windows 2000 2 5 0 Windows XP 2 5 1 Windows Server 2003 2 5 2 Windows Server 2003 R2 2 5 2 Windows Home Server 2 5 2 Windows Vista 2 6 0 Windows Server 2008 2 6 0 Windows 7 2 6 1 Windows Server 2008 R2 2 6 1 Windows 8 2 6 2 Windows Server 2012 2 6 2
    Where is Windows 10, 2016 and other which are newer (regular/server) from the requirement I wrote?

      Might System::Info help?

      C:\> cpan System::Info C:\> perl -MSystem::Info -wE"say System::Info->new->os" MSWin32 - Win7 Professional (64-bit) SP1

      Enjoy, Have FUN! H.Merijn
        I found a solution, I will use:
        my ($name, $major, $minor, $build, $id) = Win32::GetOSVersion();
        and check the values are greater than or equal to id - 2, $major - 6, $minor - 1. I guess higher version of Windows got the 262 value
