If you already know a threshold time, that after that script is considered hung. you can use timeout.
如果您已经知道了阈值时间，那么在该脚本之后将被视为挂起。您可以使用超时。
timeout 30 bash script.sh
command bash script.sh will run until it finish in less that 30 seconds or gets killed by timeout. You can adjust the time according to your environment.
命令bash脚本。sh会在30秒内跑完，或者被超时杀死。你可以根据你的环境调整时间。
