Its that time again, yet another release of wordpress is out, and this one seems important due to a few exploits. Read up here more about it http://wordpress.org/news/2010/11/wordpress-3-0-2
This script will search /var/www (changeable in a variable) for any wordpress installs and make sure its upgraded to the latest version.
It will run a backup to /root/wp_upgrade/ of all files and database before doing anything with the site in case of major catastrophe.
It pays to check each site after the upgrade to make sure plugins all worked (and upgrade plugins before the upgrade works also!).
Let me know if you have any bugs at all, or any problems.
Here’s your script to upgrade them all.
wget http://b.ri.mu/files/wordpress-upgrade-3.0.2.sh bash wordpress-upgrade-3.0.2.sh
