Drush: Listing all modules installed on multiple servers I have many servers installed on the same network, and I want to check them all to see if they need updates.  This requires me to login to each server and run drush up and check the results.

Can someone suggest a better way to do this, maybe a script or something similar?
You can add Drush Aliases for each site, and then add an alias containing all your sites.

Then:

$ drush @allsites up
