Back in the days Vinai Kopp gave a talk about ImportExport module.

In the talk is a code snippet which helps to run importExport from CLI or as a cronjob. Unfortunately it is a screenshot and I typed the snippet already a couple of times. Time to make sure it is copy pastable:

<?php

require 'html/app/Mage.php';

Mage::app();

/** @var $import Mage_ImportExport_Model_Import */$import = Mage::getModel('importexport/import');
$import->setEntity(Mage_Catalog_Model_Product::ENTITY);$file = './import.csv';

if (!$file || !file_exists($file)) {
echo 'File does not exist.';
die();
}

$validationResult =$import->validateSource($file); if ($import->getProcessedRowsCount() <= 0 || !$validationResult) { printf( 'File %s contains %s corrupt records (from a total of %s)',$file,
$import->getInvalidRowsCount(),$import->getProcessedRowsCount(),
);
foreach ($import->getErrors() as$type => $lines) {$lines = implode(', ', $lines); printf("\n::::$type :::: \nIn Line(s) $lines \n"); } die(); }$import->importSource();
\$import->invalidateIndex();
