批处理文件中的所有过程完成后，关闭Windows命令提示符 [英] close windows command prompt after all process completed in the batch file

问题描述

我需要运行两个批处理文件。在这两个bat文件中调用了两个不同的Java文件。

I have two batch files I need to run. Two different java files are called in those two bat file.

Java文件：J1.jar，J2.jar并包装在J1.bat中（xxx / java -jar J1.jar）和J2.bat
Bath文件：batch1.bat，batch2.bat
可执行程序：p1.exe，p2.exe，p3.exe，p4.exe

Java files: J1.jar, J2.jar and are wrapped in J1.bat (xxx/java -jar J1.jar) and J2.bat Bath files: batch1.bat, batch2.bat executable programs: p1.exe, p2.exe, p3.exe, p4.exe

J1会自行打开命令提示符（cmd提示符窗口＃1）并触发batch2.bat（cmd提示符窗口＃2），然后在batch2完成后，J1还会做其他几件事出口。因此，我绝对需要关闭cmd提示符窗口＃2并返回到cmd提示符窗口＃1，以便J1可以完成它必须执行的操作。

J1 will open a command prompt itself (cmd prompt window #1) and trigger batch2.bat (cmd prompt window #2) and after batch2 is done, J1 will do a couple of other things then exit. So I definitely need cmd prompt window #2 to close and return to cmd prompt window#1 so J1 can finish what it gotta do.

现在，在batch2.bat之后完成后，窗口将保留，并且显然不会将控制权返回给cmd提示窗口＃1。

Right now, after batch2.bat is done, the window stays and obviously it does not return control to cmd prompt window #1.

这是两个批处理文件

batch1.bat

call J1 batch2.bat
exit

batch2.bat

call J2 p1 p1_args
start /b J2 p2 p2_args    
start /b J2 p3 p3_args
call J2 p4 p4_args
exit

我尝试了以下操作，但没有一个会关闭cmd提示窗口＃2

I have tried the following but none of them will close cmd prompt window#2

• 开始J2 p2 p2 p2_args（这将打开另一个窗口，并且不会关闭cmd提示窗口＃2


• start J2 p2 p2_args（这将打开另一个窗口，并且不会关闭cmd提示窗口＃2）


• start / b cmd / c J2 p2 p2_args（此w不会打开新窗口，但不会关闭cmd提示窗口＃2）


• 在batch2.bat中使用exit / b（不会关闭cmd提示窗口＃2）

• start J2 p2 p2 p2_args (this will open another window and does not close cmd prompt window#2
• start "" J2 p2 p2_args (this will open another window and does not close cmd prompt window#2)
• start /b cmd /c J2 p2 p2_args (this will not open a new window but does not close cmd prompt window#2)
• use exit /b in batch2.bat (does not close cmd prompt window#2)

我还尝试将这两个p2和p3放在单独的bat文件中，并从batch2.bat调用该bat文件，但是该命令提示符窗口仍然不会

I also tried to put those two p2 and p3 in a separate bat file and call that bat file from batch2.bat, but that command prompt window still wouldn't close.

有没有办法关闭第二个命令提示符窗口？我听说使用自动热键进行窗口脚本编写，这是一种解决方案和更好的窗口脚本编写方法吗？

Is there a way to close the second command prompt window?? I heard of using auto hot key to do window scripting, is that a solution and a better way to do window scripting?

我非常感谢您的帮助。谢谢！

I gratefully appreciate any help. Thank you!

推荐答案

观察后，我注意到cmd进行了退出操作后，它不会返回提示，我将必须按Enter才能开始。我决定在出口后放一个新行，它行得通。我用以下代码行替换了出口。

After observation, I notice that after cmd took "exit", it will not return to the prompt and I will have to press enter to get things going. I decided to put a new line after the exit and it worked. I swapped out the exit with the following lines of code.

@echo off
set NLM=^
set NL=^^^%NLM%%NLM%^%NLM%%NLM%
exit %NL%
