subprocess.pid
返回子进程的进程标识符 (PID)。
如果子进程由于错误而无法衍生,则该值为 undefined
并触发 error
。
const { spawn } = require('node:child_process');
const grep = spawn('grep', ['ssh']);
console.log(`Spawned child pid: ${grep.pid}`);
grep.stdin.end();
Returns the process identifier (PID) of the child process. If the child process
fails to spawn due to errors, then the value is undefined
and error
is
emitted.
const { spawn } = require('node:child_process');
const grep = spawn('grep', ['ssh']);
console.log(`Spawned child pid: ${grep.pid}`);
grep.stdin.end();
