cmd-bat批处理命令延时方法

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
