bat countdown code

Hello everyone, meet again, I'm your friend Quanstack Jun.

bat countdown I believe everyone wants the code, here is the code.

@echo offset a=1set b=1:dao1set /a b=b-1ping -n 2 -w 500 127.1>nulclsecho countdown: %a% minutes %b% secondsif %b%==0 (goto q) else (goto dao1)if %a%==-1 (goto 5)set b=60goto dao1:qset b=60set /a a=a-1goto dao1------------------------ I am the dividing line, don't copy me in --------------------:5echo success!ping /n 3 127.1>nul

Copy

Code analysis: set /a b=b-1 means b minus 1

There may also be bugs.
