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
