[文件操作] [已解决]批处理如何判断在多余文件出现时运行程序？

@echo off & setlocal enabledelayedexpansion

for /f "delims=" %%i in ('more +18 "%~f0"') do set "#%%i=1"
set "#%~nx0=1"
for /l %%a in () do (
	for /f "delims=" %%i in ('dir /b /a-d') do (
		if "!#%%i!"=="" set exec=1
	)
	if defined exec (
		echo;执行某个程序...
		set "exec="
	)
	ping -n 5 127.1 >nul
)

pause & exit /b
