How to get the output of a spawned child_process in Node.JS?
You can do it something like below.
var spawn = require('child_process').spawn; // Create a child process var child = spawn('ls' , ['-l']); child.stdout.on('data', function (data) { console.log('ls command output: ' + data); }); child.stderr.on('data', function (data) { //throw errors console.log('stderr: ' + data); }); child.on('close', function (code) { console.log('child process exited with code ' + code); });Update: with spawnSync
var spawn = require('child_process').spawnSync; var child = spawn('ls' , ['-l','/usr']); console.log('stdout here: \n' + child.stdout);
