exit / B 0不工作 [英] exit /B 0 does not work

问题描述

我有以下问题：

我创建了一个批处理脚本，在那里调用自己（为了能够并行写一个日志）。在脚本中我启动另一个进程（如 start startServer.bat ），它启动一个java进程并始终打开。

I have created a batch script which calls itself in there (for being able to write a log in parallel). In the script I start another process (like start startServer.bat) which starts up a java process and keeps opened up all the time.

在我的原始脚本中，我等待30秒，检查进程是否正在运行，并执行：

In my original script I wait 30 seconds, check if the process is running and do an:

exit /B 0

很遗憾，这不起作用，窗口显示退出/ B 0正在计算，但窗口仍然保持打开。当我关闭窗口与其他进程（意味着子进程启动在我的.bat）我的脚本继续运行。

Unfortunately that does not work, the window shows that the exit /B 0 is being evaluated, but the window still keeps open. When I close the window with the other process (meaning the "child" processes started up in my .bat) my script continues its run.

所以：

scriptA.bat

-> in there I call: start startServer.bat
-> wait 30 seconds
-> check is server is started
-> exit /B 0
Process hangs up!

很奇怪，如果我包装另一个脚本，如：

What's very odd, if I wrap another script around, like:

scriptB.bat

-> call scriptA.bat
-----> in there I call: start startServer.bat
-----> wait 30 seconds
-----> check if server is started
-----> exit /B 0
-> scriptA.bat continues without any hangup!

我也尝试了同样退出0（没有/ B）也，同样的结果！在第一种情况下，它挂起，在第二种情况下，我的窗口按预期关闭...

I also tried the same with exit 0 (without /B) also, same result! In the first case it hangs up, in the second case my window closes as expected...

有任何人曾经有过这样的问题， ？
进程挂起！

Has anyone of you ever had such a problem before and knows what's wrong here? Process hangs up!

推荐答案

这里有一个很好的退出批处理脚本的选项：
http://www.robvanderwoude.com/exit.php

There's a good explanation of all the options for exiting a batch script here: http://www.robvanderwoude.com/exit.php

具体来说，从那个页面：
DOS在线帮助（HELP EXIT）并没有清楚表明/ B参数退出脚本的当前实例，这不一定是与退出当前脚本相同。
I.e如果脚本在CALLed代码段中，EXIT / B退出CALL，而不是脚本。

Specifically, from that page: The DOS online help (HELP EXIT) doesn't make it clear that the /B parameter exits the current instance of script which is not necessarily the same as exiting the current script. I.e. if the script is in a CALLed piece of code, the EXIT /B exits the CALL, not the script.

所以你肯定不想要 exit / b 0 在这种情况下。如果只是退出0 不工作，请尝试 GOTO：EOF 。

So you definitely don't want exit /b 0 in this case. If just exit 0 doesn't work, try GOTO:EOF.
