I use a script like this to do Drupal core upgrades in no time flat.
You can also download the attached .txt file and re-name it '6-x-upgrade.sh'.
Remember to change '6.22' to whatever the most recent version of Drupal is.
#!/bin/sh # Place this script in the directory above your drupal directory # Give it execute permissions by running 'chmod +x 6-x-upgrade.sh' # Then run it with the command './6-x-upgrade.sh' curl http://ftp.drupal.org/files/projects/drupal-6.22.tar.gz | tar zxv mv -v drupal drupal-old mv -v drupal-6.22 drupal rm -frv drupal/.htaccess rm -frv drupal/sites cp -frv drupal-old/.htaccess drupal cp -frv drupal-old/backup drupal cp -frv drupal-old/files drupal cp -frv drupal-old/sites drupal cp -frv drupal-old/webauth drupal cp -frv drupal-old/webauth_logs drupal
After it's done, just hit update.php in your browser and you're done!
