How To: Recursively Search Text Files on Linux

I have often used a handy script to recursively search text files on a linux machine (recursively grep). The script is written by Joe Grossberg and is currently on version 2.0.  The second version adds handy colorful output.

Upgrading WordPress MU from 2.6 to 2.7

I know I’m late to the game but I tried upgrading wordpress from version 2.6 to 2.7 today.  I ran into the seemingly all-too-common redirect loop which seems to have to do with the wp-config.php keys and salts.

Thanks to a comment on the wordpress forums, I was able to find a resolution, which was to remove the block of KEYS and SALTS entirely from the wp-config.php file.  Then, upon login, MU notifies you that your keys are incorrect and asks you to update them.  A simple fix to something that I thought would be a major problem.

I have to say, WordPress 2.7 is significantly better than 2.6 AND 2.7 MU is even better than that if you are running multiple blogs.  What fun!
