Mesin cari Google, Yahoo, dan MSN dalam batch file

Biasanya kalo mau cari sesuatu musti masuk ke firefox / internet explorer
baru masuk ke Google atau Yahoo, tapi kali ini di buat dalam dos prompt
tinggal kopas ke notepad :

@echo off
TITLE Internet Search
mode 27,10

(set i=)
(set g=)
(set y=)
(set m=)
cls
