Updating multiple Wordpress websites and/or blogs

I wonder if I could post for some advice about Wordpress at all?

Is there an easy or recommended way to update many wordpress sites, be they blogs on their own subfolders, or full websites on the root domain, that is not so time consuming as via FTP or through the admin panel?

The suggestions I have seen include a bash script, a plug in and something called dxmanager: http://www.wpmanagerdx.com/index.php?&cbses=1 http://wordpress.org/extend/plugins/one-click-plugin-updater/

However I am not sure how good these really are. I am wary of a shellscript as sites can move or change etc, so you'd need a strict policy to make sure the script didn't end up breaking. What do other pe开发者_JAVA技巧ople use? Have you tried any of the above and have gotchas at all?

Thanks for your time,

Darren

I find this plugin may be the solution for what you want, i find it in this article.
