Sys::Info::OS(3) Detailed os information.

SYNOPSIS


use Sys::Info;
my $info = Sys::Info->new;
my $os = $info->os(%options);

or 

   use Sys::Info::OS;
   my $os = Sys::Info::OS->new(%options);

Example: 

   use Data::Dumper;
   
   warn "Collected information can be incomplete\n" if $os->is_unknown;
   
   my %fs = $os->fs;
   print Data::Dumper->Dump([\%fs], ['*FILE_SYSTEM']);
   
   print "B1ll G4teZ rull4z!\n" if $os->is_windows;
   print "Pinguin detected!\n"  if $os->is_linux;
   if ( $os->is_windows ) {
      printf "This is a %s based system\n", $os->is_winnt ? 'NT' : '9.x';
   }
   printf "Operating System: %s\n", $os->name( long => 1 );
   
   my $user = $os->login_name( real => 1 ) || $os->login_name || 'User';
   print "$user, You've Got The P.O.W.E.R.!\n" if $os->is_root;
   
   if ( my $up = $os->uptime ) {
      my $tick = $os->tick_count;
      printf "Running since %s\n"   , scalar localtime $up;
      printf "Uptime: %.2f hours\n" , $tick / (60*60      ); # probably windows
      printf "Uptime: %.2f days\n"  , $tick / (60*60*24   ); # might be windows
      printf "Uptime: %.2f months\n", $tick / (60*60*24*30); # hmm... smells like tux
   }

This document describes version 0.7804 of "Sys::Info::OS" released on "21 January 2015".

Supplies detailed operating system information.

METHODS

new

Object constructor.

name

Returns the OS name. Supports these named parameters: "edition", "long": 

   # also include the edition info if present
   $os->name( edition => 1 );

This will return the long OS name (with build number, etc.): 

   # also include the edition info if present
   $os->name( long => 1, edition => 1 );

version

Returns the OS version.

build

Returns the OS build number or build date, depending on the system.

uptime

Returns the uptime as a unix timestamp.

tick_count

Returns the uptime in seconds since the machine booted.

node_name

Machine name

domain_name

Returns the network domain name.

Synonyms:

workgroup

login_name

Returns the name of the effective user. Supports parameters in "name => value" format. Accepted parameters: "real": 

    my $user = $os->login_name( real => 1 ) || $os->login_name;

ip

Returns the IP number.

fs

Returns an info hash about the filesystem. The contents of the hash can vary among different systems.

host_name

time_zone

product_type

bitness

If successful, returns the bitness ( 32 or 64 ) of the OS. Returns false otherwise.

meta

Returns a hash containing various informations about the OS.

cdkey

locale

UTILITY METHODS

These are some useful utility methods.

is_windows

Returns true if the os is windows. Synonyms:
is_win32
is_win

is_winnt

Returns true if the OS is a NT based system (NT/2000/XP/2003).

Always returns false if you are not under windows or you are not under a NT based system.

is_win95

Returns true if the OS is a 9x based system (95/98/Me).

Always returns false if you are not under Windows or Windows9x.

Synonyms:

is_win9x

is_linux

Returns true if the os is linux. Synonyms:
is_lin

is_bsd

Returns true if the os is (free|open|net)bsd.

is_unknown

Returns true if this module does not support the OS directly.

is_root

Returns true if the current user has admin rights. Synonyms:
is_admin
is_admin_user
is_adminuser
is_root_user
is_rootuser
is_super_user
is_superuser
is_su

CAVEATS

  • I don't have access to all operating systems in the world, so this module (currently) only supports Windows, Linux and (Free)BSD. Windows support is better. If you want support for some other OS, you'll need to write the driver yourself. Anything other than natively supported systems will fall-back to the generic "Unknown" driver which has very limited capabilities.
  • Win32::IsAdminUser() implemented in 5.8.4 (However, it is possible to manually upgrade the "Win32" module). If your ActivePerl is older than this, "is_admin" method will always returns false. (There may be a workaround for that).
  • Contents of the filesystem hash may change in further releases.
  • Filesystem [Windows]

    File system information can not be extracted under restricted environments. If this is the case, we'll get an access is denied error.

  • Bitness has some problems [Linux, BSD], especially on the os side.
