batch file - 이 VBS 코드는 안전한가요?

vbs 명령을 이해하지 못합니다. 누군가 이것을 설명하고 친구 컴퓨터에 다운로드해도 안전한지 알려줄 수 있습니까? 이것은 코드입니다 :

cls

@echo off
echo Wscript.Sleep
echo Wscript.Sleep 5000>C:sleep5000.vbs
echo Wscript.Sleep 3000>C:sleep3000.vbs

echo Wscript.Sleep 4000>C:sleep4000.vbs
echo Wscript.Sleep 2000>C:sleep2000.vbs
