在后台运行计时器的批处理。如何？

发布于 2024-10-06 06:15:30 字数 157 浏览 3 评论 0原文

我想知道是否有一种方法可以制作一个使用计时器脚本（例如 TIMEOUT 命令）的批处理文件，并在计时器运行时使批处理文件执行其他进程。但当计时器用完时，则退出。（或执行另一个小过程）我知道这意味着批处理文件必须同时运行多个进程，我只是想知道它是否可能以某种方式实现。

有什么想法吗？

您可以使用start /b cmd /c myTimeout.bat
这将在同一窗口中启动一个新应用程序（启动/？）

使用此机制，您应该能够同时执行多个作业

编辑
对于简单的超时来说，这似乎有点过大。
对于 6 秒的超时，您可以使用类似的东西

set startTime=%time%
call :timeToMs startMs startTime
set /a timeoutAt=startMs + 6000
:loop
... wait for something, like a file is created, or a CD is inserted
if job_is_ready goto :leaveTheLoop
REM Test if the timeout is reached
set currentTime=%time%
call :timeToMs nowMs currentTime
if nowMs GTR timeoutAt goto :leaveTheLoop
goto :loop

:leaveTheLoop

，它更适合真正的并行作业，例如游戏的显示作业和按键输入作业。

You can use start /b cmd /c myTimeout.bat
This starts a new application in the same window (start /?)

With this mechanism you should be able do multiple jobs at the same time

EDIT
For a simple timeout this seems to be a bit oversized.
For a timeout of 6 seconds you can use something like

set startTime=%time%
call :timeToMs startMs startTime
set /a timeoutAt=startMs + 6000
:loop
... wait for something, like a file is created, or a CD is inserted
if job_is_ready goto :leaveTheLoop
REM Test if the timeout is reached
set currentTime=%time%
call :timeToMs nowMs currentTime
if nowMs GTR timeoutAt goto :leaveTheLoop
goto :loop

:leaveTheLoop

It fits better for real parallel jobs, like a display job and a key-input job for a game.

修改了 jeb 的代码，使其可以工作：

@echo off
set /A startMs=10*%time:~9,2%+1000*%time:~6,2%+60000*%time:~3,2%+3600000*%time:~0,2%
REM the 6000 in the next line is how many milliseconds of a delay you want
set /a timeoutAt=%startMs%+6000
:loop
REM 'passive' code here:

REM Test if the timeout is reached
2>NUL set /A nowMs=10*%time:~9,2%+1000*%time:~6,2%+60000*%time:~3,2%+3600000*%time:~0,2%
if /I %nowMs% GTR %timeoutAt% goto leaveTheLoop
goto loop

:leaveTheLoop
REM do the things you want to do when the timer ends

modified the code from jeb so that it works:

@echo off
set /A startMs=10*%time:~9,2%+1000*%time:~6,2%+60000*%time:~3,2%+3600000*%time:~0,2%
REM the 6000 in the next line is how many milliseconds of a delay you want
set /a timeoutAt=%startMs%+6000
:loop
REM 'passive' code here:

REM Test if the timeout is reached
2>NUL set /A nowMs=10*%time:~9,2%+1000*%time:~6,2%+60000*%time:~3,2%+3600000*%time:~0,2%
if /I %nowMs% GTR %timeoutAt% goto leaveTheLoop
goto loop

:leaveTheLoop
REM do the things you want to do when the timer ends
