进程完成后超时或关闭 [英] timeout or close when process is finished

问题描述

我有一个X.exe程序，大约需要2-6个小时才能完成.确切时间未知，但我想将阈值设置为6.5或7个小时.如果此程序在这段时间内没有返回任何值，它将被杀死.如何使用批处理*.bat文件实施此操作?

I have a X.exe program that takes about 2-6 hours to finish. Exact time is unknown, but I'd like to implement a threshold of 6.5 or 7 hours. If this program does not return any value by this amount of time, it will be killed. How do I implement this using batch *.bat files?

这是我到目前为止的内容:一个计时器bat1.bat和一个实际的bat2.bat.

Here is what I had so far: a timer bat1.bat and an actual bat2.bat.

bat1.bat:

start cmd /C bat2.bat & timeout /t 25200 & taskkill /im X.exe /f

bat2.bat:

cd blah
bat1.bat

此方法的问题在于，只有在25200秒(或7个小时)之后，计时器才会停止运行，并且不会在该限制之前终止.我如何告诉计算机，如果X.exe程序完成了，就不再等待了吗?

The problem with this approach is that only after 25200 seconds (or 7 hours) the timer will be stopped, and it won't be terminated before that limit. How do I tell the computer that if the program X.exe is finished then don't wait anymore?

感谢您的帮助！

推荐答案

由于@Squashman，我能够自己构建脚本.似乎工作正常

thanks to @Squashman i was able to build a script on my own. seem to work fine

@echo off
setlocal enableextensions enabledelayedexpansion
set /a "checktime=60"
set /a "elapsedtime=0"
set /a "killtime=150"
set XProg=X.exe
start cmd /C runTest.bat 
timeout /t 10
:while1
    echo Go to WHILE loop.
    echo elapsedtime = %elapsedtime% 
    echo killtime = %killtime%
    set /a "timeleft = %killtime% - %elapsedtime%"
    echo timeleft = %timeleft%
    if /i %timeleft% geq 0 (
        tasklist /fi "imagename eq %XProg%" 2>NUL | find /i /n "%XProg%">NUL
        if "%ERRORLEVEL%"=="0" (
            echo %XProg% is still running...
        ) else (
            echo %XProg% is finished before timer.
        )
        set /a "elapsedtime = elapsedtime + checktime"
        timeout /t %checktime%
        goto :while1
    ) else (
        taskkill /im %XProg% /f
        echo %XProg% is terminated.
    )

经验教训: 1.难以批量比较数值变量(将diff与0进行比较) 2.第一次终止elaspedtime > killtime(可能会比killtime长一些，具体取决于它检查的频率)

lessons learned: 1. hard to compare numeric variables in batch (compare diff with 0 instead) 2. terminated first time elaspedtime > killtime (might be a bit longer than killtime depending how often it checks)
