How to kill childprocess in nodejs?

Question

Created a childprocess using shelljs

!/usr/bin/env node  require('/usr/local/lib/node_modules/shelljs/global');    fs = require("fs");      var child=exec("sudo mongod &",{async:true,silent:true});     function on_exit(){         console.log('Process Exit');         child.kill("SIGINT");         process.exit(0)     }      process.on('SIGINT',on_exit);     process.on('exit',on_exit); 

Child process is still running .. after kill the parent process

Answer 1

If you can use node's built in child_process.spawn, you're able to send a SIGINT signal to the child process:

var proc = require('child_process').spawn('mongod'); proc.kill('SIGINT'); 

An upside to this is that the main process should hang around until all of the child processes have terminated.
