I came across this handy little shell tool yesterday while I was looking up a WordPress function.
A couple of days earlier I was actually checking out a variety of debugging plugins for WordPress, the best one that I found at the time was the one I already had been using for a while, it’s called blackbox debug bar. While this plugin is really nice and more informative than the others, it doesn’t have the ability to limit debugging for admins:/
wpshell looks very promising and could be quite useful for debugging, if you are like me and feel more comfortable and in-control using the shell, you need to check it out: http://hitchhackerguide.com/2011/11/13/wpshell-a-shell-for-wordpress/. Easy to install and easy to use, It will be interesting to see how many different scenarios it could be used:)
