How to Send rest password link email to customer programmatically in magento?

Usually you need to load the customer first, then call the function on customer logic like this 

<?php
$customer_email = "[email protected]";
$customer = Mage::getModel('customer/customer');
$customer->setWebsiteId(Mage::app()->getStore()->getWebsiteId());
$customer ->loadByEmail($customer_email);

if ($customer->getId()) {
    try {
        $newResetPasswordLinkToken =  Mage::helper('customer')->generateResetPasswordLinkToken();
        $customer->changeResetPasswordLinkToken($newResetPasswordLinkToken);
        $customer->sendPasswordResetConfirmationEmail();
    } catch (Exception $exception) {
        Mage::log($exception);
    }
}
?>
