Setting Windows environment variable

Ruby
1

How can I set environment variable for windows(not for currect process)?
What command should I use?
I need functionality like setx.exe
For example I need get env variable, edit it and set it back.

ruby 1.8.5 win

Look for the older thread “Setting Windows Environment Variables”.
You’ll probably have to mess with registry (see the alst post in the
thread)

Thanks, this works for me:

require ‘win32ole’

def create_environment_variable(var_name, value)
wmi = WIN32OLE.connect(“winmgmts:\\.\root\cimv2”)
env_var = wmi.Get(‘Win32_Environment’).SpawnInstance_

env_var.Name = var_name
env_var.UserName = “”
env_var.VariableValue = value
env_var.Put_
end

var_name = ‘ABC’
value = ‘SOME_VALUE’

create_environment_variable(var_name, value)
