1、方法一：ping 缺点:时间精度为 1 秒,不够精确 Copy codeecho 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 Copy codeecho off echo wscript.sleep 5000sleep.vbs start /wait sleep.vbs start gdh.txt del /f /s /q sleep.vbs方法三：vbs cscript Copy codeecho off echo wscript.sleep 5000s
2、leep.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 Copy codeecho 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 Copy codeecho 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
