       System::Info - Factory for system specific information objects


           use System::Info;

           my $si = System::Info->new;

           printf "Hostname:              %s\n", $si->host;
           printf "Number of CPU's:       %s\n", $si->ncpu;
           printf "Processor type:        %s\n", $si->cpu_type; # short
           printf "Processor description: %s\n", $si->cpu;      # long
           printf "OS and version:        %s\n", $si->os;


           use System::Info qw( sysinfo );
           printf "[%s]\n", sysinfo ();


           $ perl -MSystem::Info=si_uname -le print+si_uname


       System::Info tries to present system-related information, like number of CPU's,
       architecture, OS and release related information in a system-independent way.  This
       releases the user of this module of the need to know if the information comes from
       Windows, Linux, HP-UX, AIX, Solaris, Irix, or VMS, and if the architecture is i386, x64,
       pa-risc2, or arm.


       Factory method, with fallback to the information in "POSIX::uname ()".

       "sysinfo" returns a string with "host", "os" and "cpu_type".

       "sysinfo_hash" returns a hash reference with basic system information, like:

         { cpu       => 'Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz (GenuineIntel 2700MHz)',
           cpu_count => '1 [8 cores]',
           cpu_cores => 8,
           cpu_type  => 'x86_64',
           distro    => 'openSUSE Tumbleweed 20171030',
           hostname  => 'foobar',
           os        => 'linux - 4.13.10-1-default [openSUSE Tumbleweed 20171030]',
           osname    => 'Linux',
           osvers    => '4.13.10-1-default'

   si_uname (@args)
       This class gathers most of the uname(1) info, make a comparable version. Takes almost the
       same arguments:

           a for all (can be omitted)
           n for nodename
           s for os name and version
           m for cpu name
           c for cpu count
           p for cpu_type


       There are more modules that provide system and/or architectural information.

       Where System::Info aims at returning the information that is useful for bug reports, some
       other modules focus on a single aspect (possibly with way more variables and methods than
       System::Info does supports), or are limited to use on a specific architecture, like
       Windows or Linux.

       Here are some of the alternatives and how to replace that code with what System::Info
       offers. Not all returned values will be exactly the same.

        use Sys::Hostname;
        say "Hostname: ", hostname;


        use System::Info;
        my $si = System::Info->new;
        say "Hostname: ", $si->host;

       Sys::Hostname is a CORE module, and will always be available.

        use Unix::Processors;
        my $up = Unix::Processors->new;
        say "CPU type : ", $up->processors->[0]->type;
        say "CPU count: ", $up->max_physical;
        say "CPU cores: ", $up->max_online;
        say "CPU speed: ", $up->max_clock;


        use System::Info;
        my $si = System::Info->new;
        say "CPU type : ", $si->cpu;
        say "CPU count: ", $si->ncpu;
        say "CPU cores: ", $si->ncore;
        say "CPU speed: ", $si->cpu =~ s{^.*\b([0-9.]+)\s*[A-Z]Hz.*}{$1}r;

       The number reported by max_physical is inaccurate for modern CPU's

       Sys::Info has a somewhat rigid configuration, which causes it to fail installation on e.g.
       (modern versions of) CentOS and openSUSE Tumbleweed.

       It aims at returning a complete set of information, but as I cannot install it on openSUSE
       Tumbleweed, I cannot test it and show the analogies.

        use Sys::CPU;
        say "CPU type : ", Sys::CPU::cpu_type  ();
        say "CPU count: ", Sys::CPU::cpu_count ();
        say "CPU speed: ", Sys::CPU::cpu_clock ();


        use System::Info;
        my $si = System::Info->new;
        say "CPU type : ", $si->get_cpu;         # or ->cpu
        say "CPU count: ", $si->get_core_count;  # or ->ncore
        say "CPU speed: ", $si->get_cpu =~ s{^.*\b([0-9.]+)\s*[A-Z]Hz.*}{$1}r;

       The speed reported by Sys::CPU is the current speed, and it will change from call to call.

       Sys::CPU is not available on CPAN anymore, but you can still get is from BackPAN.
