Updating Drupal

The best way to handle minor updates is to first back everything up (your web directory and your database) then download the new version of drupal to a directory (lets use ~/drupalupdate as the download directory and /var/www/html as the webdirectory) cd into the download directory and run the following command

find * -type f -exec echo cp {} /var/www/html/{} \;
This one just test everything and echos what it would really do.  If everything looks good run

find * -type f -exec cp {} /var/www/html/{} \;
