批處理延時啓動的幾個方法

方法一：ping 
缺點:時間精度爲1秒,不夠精確 


方法二：vbs start /wait 
缺點：生成臨時文件 
優勢：時間精度爲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 
優勢：時間精確，CPU佔用低，是最佳選擇 

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

方法五：for+set+if，時間精度爲0.01秒 
缺點：CPU佔用高，語句過長，不經常使用 

@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

我使用的是這個批處理，惟一很差就是有窗口 

@echo  off
:: 模擬進度，有剩餘時間、已完成進度、進度條的顯示
:: code by
color 1f
title.
mode con lines=10
rem   進度條 ▉▉▉▉▉
set work=0
set n=0
set mo=0
set number=0
rem   all是總數
set all=10
set time=%all%
:show

:check
if %number% GTR %mo% set num=%num%▉&set /a mo=%mo%+1&goto check

:2

cls
echo   進度： %n% / %all%           ★程序正在啓動請稍等★           剩餘時間:%time%秒
echo.
echo.
echo                                   完成 %work% %%%
echo.
if not "%num%"=="" echo       %num%
if not "%num%"=="" echo       %num%

if %work%==100 goto end

ping 127.1 -n 2 >nul
set /a n=%n%+1
set /a time=%all%-%n%
set /a work=(%n%)*100/(%all%)
set /a number=%work%/3
set /a number=%number%+1
goto show
endlocal

:end
@echo  off
start C:\Progra~1\tools\xsdy\1.exe
exit
