title: Magento - Command line indexer doesn't accept any command
body: <p>I stumbled upon a weird problem with Magento indexer. I tried to run it via command line, but, no matter what I write, I get back the help screen. Even if I run <code>php -f indexer.php info</code>, I just get the help screen, but no error messages, either on screen or in the system log. What should I check to find out why the indexer doesn't want to run?</p>
  
  <p>Thanks in advance for the answers.</p>
