Question

出于测试目的，我运行了几个（100s} expect个脚本。所有这些都是从同一个父级生成的（有时它的pid是1）。有没有办法在不改变源代码的情况下一次性杀死它们而而不会破坏父进程本身？类似的东西：

[root@devx-csb4 expect_scripts] kill -9 <child of pid=...>

所有期望脚本都是一样的但是循环运行;请参阅以下ps -ef | grep milind

Answer 1

使用公共子字符串为所有人命名并使用 pkill(1)
使用ps，获取父进程ID，并终止附加到父进程的所有PID。当父进程为1时，这是不可取的。请注意，使用kill -9 pid=的概念遇到同样的问题 - 所有系统守护程序进程都是PID 1的子进程。
保留期望脚本名称的列表;运行ps并为列表中的每个名称找到PID;杀了它。

如何杀死从同一个父级产生的几个子进程？
