passthru(command, [options], [callback]);

For example, do an ls -la in the current directory:

var passthru = require('passthru');
passthru('ls -la', function(err) {
    // ...

You can also pass command as an array of strings. This is mandatory for arguments containing spaces and other special characters.

passthru(['ls', '-la'], function(err) {
    // ...

You can use any options supported by child_process.spawn:

passthru('ls -la', {cwd: '/tmp'}, function(err) {
    // ...
