process.kill(pid[, signal])

• pid <number> 进程标识

  \pid <number> A process ID

• signal <string> | <number> 要发送的信号,可以是字符串或数字。默认值:'SIGTERM'。

  \signal <string> | <number> The signal to send, either as a string or number. Default: 'SIGTERM'.

process.kill() 方法将 signal 发送到由 pid 标识的进程。

\The process.kill() method sends the signal to the process identified by pid.

信号名称是字符串,例如 'SIGINT' 或 'SIGHUP'。有关详细信息,请参阅 信号事件 和 kill(2)。

\Signal names are strings such as 'SIGINT' or 'SIGHUP'. See Signal Events and kill(2) for more information.

如果目标 pid 不存在,则此方法将抛出错误。作为特殊情况,可以使用信号 0 来测试进程是否存在。如果使用 pid 来杀死进程组,则 Windows 平台将抛出错误。

\This method will throw an error if the target pid does not exist. As a special case, a signal of 0 can be used to test for the existence of a process. Windows platforms will throw an error if the pid is used to kill a process group.

尽管此函数的名字是 process.kill(),但它实际上只是信号发送者,就像 kill 系统调用。发送的信号可能会做其他事情而不是杀死目标进程。

\Even though the name of this function is process.kill(), it is really just a signal sender, like the kill system call. The signal sent may do something other than kill the target process.

import process, { kill } from 'node:process';
process.on('SIGHUP', () => {
 console.log('Got SIGHUP signal.');
});
setTimeout(() => {
 console.log('Exiting.');
 process.exit(0);
}, 100);
kill(process.pid, 'SIGHUP');const process = require('node:process');
process.on('SIGHUP', () => {
 console.log('Got SIGHUP signal.');
});
setTimeout(() => {
 console.log('Exiting.');
 process.exit(0);
}, 100);
process.kill(process.pid, 'SIGHUP');拷贝

当 Node.js 进程收到 SIGUSR1 时,Node.js 将启动调试器。参见 信号事件。

\When SIGUSR1 is received by a Node.js process, Node.js will start the debugger. See Signal Events.
