The large number of sites we host means that performing manual changes would require too much time and carries a chance of error. I’ve come up with a simple solution.

I first create a PHP script that bootstraps Drupal. Here is an example of a script that will rebuild the menu router tables.

// Bootstrap
require_once('includes/bootstrap.inc');
require_once('includes/common.inc');
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
 
// Rebuild menus
menu_rebuild();
print 'Menu rebuild complete\n';

I name this script rebuild_menus.php and upload it to my Drupal directory. Then, I create a text file on my desktop that contains a list of all the Drupal websites. This is an abbreviated example:

http://example1.com
http://example2.com
http://example3.com
http://example4.com

Finally, I execute the script on all the sites by running the following command:

for url in `cat list.txt`; do echo "Running script on $url"; curl $url/rebuild_menus.php; echo; done
