批处理延时启动的几个方法

方法一：ping

缺点:时间精度为1秒,不够精确

@echo off @ping 127.0.0.1 -n 6 >nul start gdh.txt

方法二：vbs start /wait

缺点：生成临时文件

有点：时间精度为0.001秒，精度高

@echo off echo wscript.sleep 5000>sleep.vbs start /wait sleep.vbs start gdh.txt del /f /s /q sleep.vbs

方法三：vbs cscript

@echo off echo wscript.sleep 5000>sleep.vbs @cscript sleep.vbs >nul start gdh.txt del /f /s /q sleep.vbs

方法四：choice

优点：时间精确，CPU占用低，是最佳选择

@echo off choice /t 5 /d y /n >nul start gdh.txt

方法五：for+set+if，时间精度为0.01秒

缺点：CPU占用高，语句过长，不常用

@echo off setlocal enableextensions echo %time% call :ProcDelay 500 echo %time% start gdh.txt :ProcDelay delayMSec_ setlocal enableextensions for /f "tokens=1-4 delims=:. " %%h in ("%time%") do set start_=%%h%%i%%j%%k :_procwaitloop for /f "tokens=1-4 delims=:. " %%h in ("%time%") do set now_=%%h%%i%%j%%k set /a diff_=%now_%-%start_% if %diff_% LSS %1 goto _procwaitloop endlocal & goto :EOF
