There are lots of automatic WordPress upgrade plugins, but do to some server restrictions I couldn’t get them to work correctly. So I made a simple bash file to upgrade this WordPress site for me. The script only backs up the current web site directory, and does not do any DB backups. I used this script to upgrade from 2.7.1 to 2.8 and just today from 2.8 to 2.8.1 and the blog is still up, so I guess it works OK!

Variable definitions:

• WORDPRESS_DOWNLOAD_URL – the URL of the latest WordPress version to download
• WORDPRESS_LATEST – the file name of the downloaded WordPress version
• WORDPRESS_EXTRACT – the directory the WordPress files are extracted when the download file is uncompressed
• WORDPRESS_DIR – the web root directory where the WordPress files will be copied to, and where your wp-config and wp-content files will be copied to (your blogs web root)

To use, create a new file, say wordpress_upgrade.txt, copy and paste the code below, and make wordpress_upgrade.txt executable (chmod 755 wordpress_upgrade.txt). Run via ./wordpress_upgrade.txt and when its done, sign into your blog to run any DB upgrades. I run this script from my home directory, and “public_html” is where my WordPress files reside. This script can be run from any location, as long as the paths are setup correctly and accessible.

Note: this script does not perform a database backup!

echo "Should be done, now go to WordPress Admin to upgrade!"
