check if child_process has ended in node.js?

I am creating a cakefile using node.js and want to know if a child_process has ended before moving on the next one.

{exec} = require 'child_process'
 exec 'casperjs test.js', (err, stdout, stderr) ->
        err && throw err
        log stdout
        if //exec has finished
          log "finished executing"

Alternativly you can use 'execSync", in order to go on step by step

var c = require('child_process');
var cliCommand = 'ls';
var result = c.execSync(cliCommand);

When the callback of exec is called, the process has already been terminated. There's no need to add an additional check.

For spawn, you can bind an exit event listener.
