require ‘win32ole’
network=WIN32OLE.new(“Wscript.Network”)
puts network.username

#or
puts ENV[‘username’]
#for win95/98 use
puts ENV[‘userid’]

#or (stolen from www.,rubytips.org)
require ‘Win32API’
name = " " * 128
size = “128”
Win32API.new(‘advapi32’,‘GetUserName’,[‘P’,‘P’],‘I’).call(name,size)
puts name.unpack(“A*”)

Take your pick.

NT/2K/2K3/Vista systems have a environment variable for interactive
users:

irb(main):001:0> ENV[‘USERNAME’]
=> “Luis”

So you only need to asign ENV[‘USERNAME’] and will get the current
username.

If your process is not an interactive one (ala, a Windows service)
then this variable will be nil or the special account used for it
(LocalService).

HTH,

Thanks all for the help. It’s working now. Thanks!

This is the one function of the ‘etc’ library that works on Windows:

require ‘etc’
puts Etc.getlogin

Or, you can use the sys-admin library, which provides much more
functionality on Windows:

gem install sys-admin
require ‘sys/admin’

puts Sys::Admin.get_login
