从节点应用程序终止进程

Question

I've used the following code to run some process which is working OK,my question is if there any option to kill this process on demand (by code)

    var exec = require('child_process').exec;
    var cmd = 'any command';

    exec(cmd, function(error, stdout, stderr) {
....
    });

Answer 1

var child = exec(cmd, function(error, stdout, stderr) { ... });

// When you want to kill it:
child.kill(SIGNAL);

See the documentation .

Answer 2

exec returns a childProcess object

you can kill it using childProcess.kill([signal]) - signal is SIGTERM if not specified
