我该如何杀死这个bash脚本？

[英]how do I kill this bash script?

原文 2010-09-14 14:13:22 6 2 linux/ bash

I have written a bash script, A, that is calling another script, B, over 1000 times in a loop. 我编写了一个bash脚本A，它在循环中调用另一个脚本B超过1000次。

Ctrl + C kills only script B, only one iteration. Ctrl + C仅杀死脚本B，只杀死一次。 Script A keeps running and calling script B again. 脚本A继续运行并再次调用脚本B.

Can I rewrite something in these scripts so that Ctrl + C will kill script A? 我可以在这些脚本中重写一些内容，以便Ctrl + C会杀死脚本A吗？

2 个解决方案

you can trap your killing signal and do whatever you want (killing A instead of B, for instance). 你可以捕获你的杀戮信号并做你想做的任何事情（例如杀死A而不是B）。 See here how. 看这里怎么样。 If you use it in B, try making it kill its parent... 如果你在B中使用它，试着让它杀死它的父...

The correct thing to do is to ensure that both scripts are executed in the same process group . 正确的做法是确保两个脚本都在同一个进程组中执行。 Then they both will get SIGINT signal when you press Ctrl-C . 然后当你按Ctrl-C时它们都会得到SIGINT信号。

From what you tell, for some reason they got into the different process groups. 从你所说的，由于某种原因，他们进入了不同的过程组。 This may happen if the shell which executes script A thinks that it (the shell) is interactive. 如果执行脚本A的shell认为它（shell）是交互式的，则可能发生这种情况。 It's hard to tell more from your description -- feel free to paste some sample code (and describe how you launch the scripts) and we'll take a look. 很难从你的描述中得到更多信息 - 随意粘贴一些示例代码（并描述如何启动脚本），我们将看一看。
