Executing shell script from code

Try this

// app.jsrequire('child_process').spawn('sh', ['test.sh'], {stdio: 'inherit'});

The code works for me perfectly, without any changes. When you say you are not able to see any response, does the process hang? what is the final outcome? I doubt the sudo command in the script is causing some issues. Can you eliminate that and change? I don't have sudo access, so it failed on prompt.

Some diagnostic steps:

• Print the child object, after the excec call. This will print the process information pertinent to the child. This will make sure the child is started.
• Install a child terminator callback, and print a debug information in it. This will make sure the child is ended.
• If still problem persists, install child stream hooks. This will make sure the instantaneous prints in the streams are output immediately, rather than at the end.

Modified exec_process.js

var exec = require('child_process').exec;var result = function(command, cb){    var child = exec(command, function(err, stdout, stderr){        if(err != null){            return cb(new Error(err), null);        }else if(typeof(stderr) != "string"){            return cb(new Error(stderr), null);        }else{            return cb(null, stdout);        }    });    console.log(child);    child.on('close', function(code) {      console.log('child ended with: ' + code);    });    child.on('error', function(err) {      console.log('child errd with: ' + err);    });    child.stdout.on('data', function(d) {      console.log('child stdout: ' + d);   });}exports.result = result;

Hope this helps.
