I'm confused by command 'echo'.
I want to create a batch file with a script:

::Create Boot.bat
echo @echo off >> D:\Boot\Boot.bat
echo ping 127.0.0.1 -n 1 >nul >> D:\Boot\Boot.bat
echo tasklist ^| find /i "gpupdate.exe" >> D:\Boot\Boot.bat
echo if %errorlevel%==0 taskkill /f /im gpupdate.exe >> D:\Boot\Boot.bat

I want to get a script as below:

@echo off
ping 127.0.0.1 -n 1 >nul
tasklist | find /i "gpupdate.exe"
if %errorlevel%==0 taskkill /f /im gpupdate.exe

How should I change the first script?
Thank you all in advance.
