    How to upgrade wordpress from Unix Shell?

    1) Backup existing database and wordpress directory

    Lets take an example of 28Nov2006.

    Type the following commands at shell prompt:
    $ mkdir /backup/wp/28nov2006
    $ mysqldump -u user -p WP-DATABASENAME > /backup/wp/28nov2006/blog.db.sql
    $ tar -zcvf /backup/wp/28nov2006.tar.gz /var/www/html/blog

    2) Download latest wordpress CMS

    $ cd /tmp
    $ wget http://wordpress.org/latest.zip
    $ unzip latest.zip

    3) Overwrite all new files
    $ cd /var/www/html/blog
    $ cp -avr /tmp/wordpress/* .
    $ rm -rf /tmp/wordpress /tmp/latest.zip
    Open a browser and run update script such as http://yourblog.com/wp-admin/upgrade.php

    And you are done. Thanks to UNIX shell access. It just took less than 1 minute!!!

    Replace path names and database name with actual values.

    In case, if something goes wrong, you can always restore old database and files from /backup

    Re: How to upgrade wordpress from Unix Shell?

    Thanks to this post I was able to upgrade WP on my sites in no time. I dreaded having to wait for the slow ftp process to complete with my sites being down.

    After testing the process on one site and seeing how fast it was, I did not even bother activating the maintenance mode plug in on the other sites. My users tend to get pissed off when the site goes down for a few mins and following the steps you provided prevents this.

    One thing I did before copying over the new WP files to the site, was delete the wp-contents folder from the new WP files. I did not want it over writing what I had in my existing WP-contents folder (plug-ins and themes)

    Thanks again.
