Windows batch: sleep
提问by Claudiu
How do I get a Windows batch script to wait a few seconds?
如何让 Windows 批处理脚本等待几秒钟？
sleepand waitdon't seem to work (unrecognized command).
sleep并且wait似乎不起作用（无法识别的命令）。

You can try
你可以试试
ping -n XXX 127.0.0.1 >nul
where XXX is the number of seconds to wait, plus one.
其中 XXX 是等待的秒数加一。

timeout /t 10 /nobreak > NUL
/tspecifies the time to wait in seconds
/t指定等待的时间（以秒为单位）
/nobreakwon't interrupt the timeout if you press a key (except CTRL-C)
/nobreak如果您按下某个键，则不会中断超时（CTRL-C 除外）
> NULwill suppress the output of the command
> NUL将抑制命令的输出

Microsoft has a sleep function you can call directly.
微软有一个睡眠功能，你可以直接调用。
Usage: sleep time-to-sleep-in-seconds
sleep [-m] time-to-sleep-in-milliseconds
sleep [-c] commited-memory ratio (1%-100%)
You can just say sleep 1for example to sleep for 1 second in your batch script.
例如，您可以在批处理脚本中说sleep 1以睡眠 1 秒。
IMO Ping is a bit of a hack for this use case.
对于这个用例，IMO Ping 是一个小技巧。

For a pure cmd.exe script, you can use this piece of code that returns the current time in hundreths of seconds.
对于纯 cmd.exe 脚本，您可以使用这段代码以百秒为单位返回当前时间。
:gettime
set hh=%time:~0,2%
set mm=%time:~3,2%
set ss=%time:~6,2%
set cc=%time:~-2%
set /A %1=hh*360000+mm*6000+ss*100+cc
goto :eof
You may then use it in a wait loop like this.
然后您可以在像这样的等待循环中使用它。
:wait
call :gettime wait0
:w2
call :gettime wait1
set /A waitt = wait1-wait0
if !waitt! lss %1 goto :w2
goto :eof
And putting all pieces together:
并将所有部分放在一起：
@echo off
setlocal enableextensions enabledelayedexpansion
call :gettime t1
echo %t1%
call :wait %1
call :gettime t2
echo %t2%
set /A tt = (t2-t1)/100
echo %tt%
goto :eof
:wait
call :gettime wait0
:w2
call :gettime wait1
set /A waitt = wait1-wait0
if !waitt! lss %1 goto :w2
goto :eof
:gettime
set hh=%time:~0,2%
set mm=%time:~3,2%
set ss=%time:~6,2%
set cc=%time:~-2%
set /A %1=hh*360000+mm*6000+ss*100+cc
goto :eof

I rely on JScript. I have a JScript file like this:
我依赖JScript。我有一个这样的 JScript 文件：
// This is sleep.js
WScript.Sleep( WScript.Arguments( 0 ) );
And inside a batch file I run it with CScript(usually it is %SystemRoot%\system32\cscript.exe)
在批处理文件中，我使用CScript运行它（通常是%SystemRoot%\system32\cscript.exe）
rem This is the calling inside a BAT file to wait for 5 seconds
cscript /nologo sleep.js 5000

Or something like that.
或类似的东西。

Heh, Windows is uhm... interesting. This works:
呵呵，Windows 是呃……很有趣。这有效：
choice /T 1 /d y > NUL
choicepresents a prompt asking you yes or no. /d ymakes it choose yes. /t 1makes it wait a second before typing it. > NULsquashes output.
choice出现一个提示，询问您是或否。/d y让它选择是。/t 1让它在输入之前等待一秒钟。> NUL挤压输出。

I just wrote my own sleep which called the Win32Sleep API function.
我刚刚编写了自己的 sleep，它调用了Win32 Sleep API 函数。
