error trap

The trap command is a more generalized solution for trapping more serious errors based on the signals raised when a command fails, such as core dump, memory error, or when a command has been forcibly terminated by a kill command.

trap命令是用于跟踪更为严重的错误的通用型解决方案，基于命令失败时发出的信号，如内核转储、内存错误或kill命令强行终止了命令。
