check if child_process has ended in node.js?
child-process, javascript, node.js
Solution
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.
Problem
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" ```
