問題：
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).我有一個 bash 腳本，它啓動一個子進程，該進程不時崩潰（實際上，掛起）並且沒有明顯的原因（封閉源代碼，所以我無能爲力）。 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，我希望能夠在給定的時間內啓動此進程，如果在給定的時間後沒有成功返回，則將其終止。
Is there a simple and robust way to achieve that using bash?有沒有一種簡單而強大的方法可以使用 bash 來實現這一目標？
