You can do it with node.js' exec.

# install node.js (debian/ubuntu)
sudo apt-get install nodejs

# run node.js CLI
node

From an example found here:

var sys = require('sys')
var exec = require('child_process').exec;
function puts(error, stdout, stderr) { sys.puts(stdout) }
exec("ls -la", puts);

This outputs a directory listing.
