One method is to run the command "shutdown.exe" with parameters:

  system('shutdown.exe -r -f -t 0')

To get a list of parameters, open a console window and enter

  shutdown.exe /?

Here are a few ways.  You'll need admin privileges on any box you run
it against.

Using WMI via win32ole locally.
<code>

LogOff         = 0
ForcedLogOff   = 4
Shutdown       = 1
ForcedShutdown = 5
Reboot         = 2
ForcedReboot   = 6
PowerOff       = 8
ForcedPowerOff = 12

require 'win32ole'

wmi = WIN32OLE.connect("winmgmts:\\\\.\\root\\cimv2")
list = wmi.execquery("Select * from Win32_OperatingSystem",nil,48)

list.each do |item|
  item.win32Shutdown(LogOff)
end
</code>

Using ruby-wmi (gem install ruby-wmi) locally.
<code>

require 'ruby-wmi'
#you'll need the same constants as above

host = 'computername'
os    = WMI::Win32_OperatingSystem.find(:first)
os.win32shutdown(LogOff )

</code>


Using win32ole remotely.
<code>
require 'win32ole'
# constants
computer_name = 'host'
wmi = WIN32OLE.connect("winmgmts:\\\\#{computer_name}\\root\\cimv2")
list = wmi.execquery("Select * from Win32_OperatingSystem",nil,48)

list.each do |item|
  item.win32Shutdown(LogOff )
end

</code>

Using ruby-wmi remotely.
<code>

require 'ruby-wmi'
# constants
host = 'computername'
os    = WMI::Win32_OperatingSystem.find(:first, :host => host)
os.win32shutdown(LogOff )

</code>

Ok, you'll need the 'Shutdown' privilege for a local machine and the
RemoteShutdown privilege for a remote machine.

LogOff         = 0
ForcedLogOff   = 4
Shutdown       = 1
ForcedShutdown = 5
Reboot         = 2
ForcedReboot   = 6
PowerOff       = 8
ForcedPowerOff = 12

require 'rubygems'
require 'ruby-wmi'


os = WMI::Win32_OperatingSystem.find( :first, :privileges =>
[WMI::Privilege::Shutdown] )
os.win32shutdown( Shutdown )

Hi All,

I got simple solution. But need t sharp it.

I got code to shutdown my machine, getting ipconfig in my machine 
etc..,(whatever possible to get via command prompt.)

My Code:

system('ipconfig')

I got my IP Address.

Problem:

a= system('ipconfig')

puts a

I got only true. Please help to store the content in single variable.

Hi..
I tried your code and all OK!

Try this:

def myIpConfig
 system('ipconfig') // or puts system('ipconfig')
end

myIpConfig // print your ip config

Try with backtick operator:
a = `ipconfig`

If you want only IP Address, you can do something like this:
a = `ipconfig`.scan(/IP Address.+?: (.+)\r/).to_s

Use backticks:

>> a = `ipconfig`
=> "\r\nWindows IP Configuration\r\n\r\n\r\nEthernet adapter Wireless
Network Connection 2:\r\n\r\n        Connection-specific DNS Suffix  .
: \r\n        IP Address. . . . . . . . . . . . : 192.168.1.101\r\n
    Subnet Mask . . . . . .
. . . . . : 255.255.255.0\r\n        Default Gateway . . . . . . . . .
: 192.168.1.1\r\n"
>> a
=> "\r\nWindows IP Configuration\r\n\r\n\r\nEthernet adapter Wireless
Network Connection 2:\r\n\r\n        Connection-specific DNS Suffix  .
: \r\n        IP Address. . . . . . . . . . . . : 192.168.1.101\r\n
    Subnet Mask . . . . . .
. . . . . : 255.255.255.0\r\n        Default Gateway . . . . . . . . .
: 192.168.1.1\r\n"

Solution:
  a = `ipconfig`

No no, it's possible, i tried:
  var = system('ipconfig')
  puts var
and all is fine.

try this:
  var = "#{system('ipconfig')}"
  puts "#{var}"

I think it must work.
