出口/ B 0不起作用 [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自称在那里（下也可以写入日志并行）。在脚本，我开始另一个进程（如启动startServer.bat ），它启动一个java进程，并不断开辟了所有的时间。

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.

在我最初的剧本我等待30秒，检查进程正在运行，做一个：

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

exit /B 0

不幸的是，这并不工作，窗口显示的退出/ B 0正在评估，但窗口仍保持打开状态。当我关闭窗口与其他工艺（意为子进程在我的蝙蝠启动）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!

什么是很奇怪的，如果我环绕，像另一个脚本：

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!

我也试过，退出0相同（无/ B）也同样的结果！在第一种情况下，它挂断，在第二种情况下我的窗口关闭预期...

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...

有你们有谁收到这样的问题，并且知道什么是错在这里？
流程挂断！

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

推荐答案

还有的在这里退出批处理脚本的所有选项一个很好的解释：
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

具体而言，从该页面：
在DOS联机帮助（HELP EXIT）的/ b参数退出脚本的当前实例，这不一定是一样退出当前脚本无法说清楚。
即如果脚本是在一个名为一块code的，退出/ 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，你绝对不希望退出/ B 0 在这种情况下。如果只是 0退出不工作，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.
