=== Fix permissions on your Drupal site ===
<source lang="bash">
DROOT='/var/www/example.com/www/drupal'
USER=greg
WEBGROUP=www-data
sudo chown -R $USER:$WEBGROUP $DROOT/
sudo find $DROOT/ -type d -exec chmod u=rwx,g=rx,o= '{}' \;
sudo find $DROOT/ -type f -exec chmod u=rw,g=r,o= '{}' \;
sudo find $DROOT/sites -type d -name files -exec chmod ug=rwx,o= '{}' \;
for d in "$DROOT/sites/*/files"; do sudo find $d -type d -exec chmod ug=rwx,o= {} \; ; find $d -type f -exec chmod ug=rw,o= {} \; ; done
</source>

The $USER must logout and login again to reload their group memberships. Alternatively, just issue <code>su - $USER</code> or <code>newgrp</code> (with no arguments); or start a new shell which will inherit the new group memberships.

The linux command <code>namei</code> is very handy at showing you the directory traversal all the way to your destination to show ownership, permissions etc. Use the <code>-m</code> to show mode or <code>-l</code> to show a long listing
