util.convertProcessSignalToExitCode(signalCode)

• signalCode <string> 一个信号名称（例如，'SIGTERM'，'SIGKILL'）。
• 返回：<number> | <null> 退出代码，或者如果信号无效则为 null。

util.convertProcessSignalToExitCode() 方法将信号名称转换为相应的 POSIX 退出代码。根据 POSIX 标准，由信号终止的进程的退出代码计算方式为 128 + signal number。

🌐 The util.convertProcessSignalToExitCode() method converts a signal name to its corresponding POSIX exit code. Following the POSIX standard, the exit code for a process terminated by a signal is calculated as 128 + signal number.

import { convertProcessSignalToExitCode } from 'node:util';

console.log(convertProcessSignalToExitCode('SIGTERM')); // 143 (128 + 15)
console.log(convertProcessSignalToExitCode('SIGKILL')); // 137 (128 + 9)
console.log(convertProcessSignalToExitCode('INVALID')); // nullconst { convertProcessSignalToExitCode } = require('node:util');

console.log(convertProcessSignalToExitCode('SIGTERM')); // 143 (128 + 15)
console.log(convertProcessSignalToExitCode('SIGKILL')); // 137 (128 + 9)
console.log(convertProcessSignalToExitCode('INVALID')); // null拷贝

当处理进程时，根据终止进程的信号确定退出代码，这尤其有用。

🌐 This is particularly useful when working with processes to determine the exit code based on the signal that terminated the process.
