I often find that after recreating a Drupal site locally to do some testing that I have left CSS and JS aggregation turned on. This can be turned off easily enough via the performance page, but this often breaks the flow of what I am doing. As an alternative I use Drush to reset the values via the command line.
The Drush command variable-set can be used to alter any value in the variable table. The two values needed for CSS and JavaScript aggregation are preprocess_css and preprocess_js. To turn these values of we just set them to 0 like this.
