I may be a devout rubyist, but I still have a soft spot for WordPress — and maybe even a little for PHP too. One of the things I think is lacking is a good way to manage WordPress updates since, as we all know, WordPress updates constantly. I wrote this quick thor script to help me update to the latest version from the command line so I can do quick version testing. As an added bonus, there is also an export task as well which will simulate doing a wordpress XML export from the dashboard.

So, for all you WordPress guys out there who hate doing manual updates, check this out. It may make life a little bit easier.

1. install thor gem
> gem install thor

2. add wordpress script to your wordpress install root and chmod it
> chmod a+x wordpress

3. update wordpress
> ./wordpress update

4. export wordpress (php must have CLI support)
> ./wordpress export | gzip -c > ~/Desktop/wp_export.xml.gz
