Split a different way:
fs.readFile(myFile, function(err, lines) {
if (err) console.log('FILE read file[' + myFile + '] error[' + err +
']');
// convert blob to string, split on newline, but split adds empty line
to end of array, use replace to fix
var array = lines.toString().replace(/\n$/, '').split('\n');
console.log('Total lines['+array.length+']');
}
Cheers,
Warren
