For anyone trying to use Drupal code in command line and having issues, use the following code as an example. When using Drupal in CLI, a warning about "Undefined index: REMOTE_ADDR" will appear for bootstrap.inc file. The following code fixes this.

drupalExecuteFromCLI.php

<?php

$uid = 1;
// Prevent this from running under Apache.
if (array_key_exists('REQUEST_METHOD', $_SERVER)) {
  echo 'Nope.  Not executing except from the command line.';
  exit(1);
}

// Set HTTP_HOST or Drupal will refuse to bootstrap.
$_SERVER['HTTP_HOST'] = 'example.org';
$_SERVER['REMOTE_ADDR'] = '127.0.0.1';

// Initialise Drupal.
define('DRUPAL_ROOT', getcwd());
include_once 'includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

/*
