问题：
I have a bash script that launches a child process that crashes (actually, hangs) from time to time and with no apparent reason (closed source, so there isn't much I can do about it).我有一个 bash 脚本，它启动一个子进程，该进程不时崩溃（实际上，挂起）并且没有明显的原因（封闭源代码，所以我无能为力）。 As a result, I would like to be able to launch this process for a given amount of time, and kill it if it did not return successfully after a given amount of time.因此，我希望能够在给定的时间内启动此进程，如果在给定的时间后没有成功返回，则将其终止。
Is there a simple and robust way to achieve that using bash?有没有一种简单而强大的方法可以使用 bash 来实现这一目标？
