With your current code, node.js is trying to execute the following:

cd ~/Desktop find -type f -printf %T+\\t%p\\n | sort -n

if you try run that outside of node, you'll get the same results.

You need to deliminate the commands using either && or ;, like so:

var command = ' cd ~/Desktop &&'
command +=' find -type f -printf %T+\\t%p\\n | sort -n' 

exec(command, function (error, stdout, stderr) {

});

A perhaps more elegant approach:

var commands = [];
commands.push('cd ~/Desktop');
commands.push('find -type f -printf %T+\\t%p\\n | sort -n');

var command = commands.join(' && ');

exec(command, function (error, stdout, stderr) {

});
