The same feature is now built-in with node v0.12: https://nodejs.org/api/child_process.html#child_process_child_process_execsync_command_options
Execute shell command synchronously. Use this for migration scripts, cli programs, but not for regular server code.
$ curl http://npmjs.org/install.sh | sh$ cd /path/to/your/project
$ [sudo] npm install exec-syncWarning: 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).
