Execute shell command synchronously. Use this for migration scripts, cli programs, but not for regular server code.

$ cd /path/to/your/project
$ [sudo] npm install exec-sync

Using exec-sync from node.js

Warning: use only for special operation or command line scripts written with node. Don't use this for regular server code or it will ruin the responsiveness of your server.

var execSync = require('exec-sync');

var user = execSync('echo $USER');
console.log(user);

By default, an Error is thrown if stderr is not empty. Alternatively, the function can return an object with both stdout and stderr as properties by passing true as a second argument (returnOutAndErr).
