Exist a Drush command to update all the contents? We have a client who was adding content to a separated dev server, the dev server is whitelisted only and doesn't allow incoming/outgoing connections to a lot of services.

The client was adding videos with the video embed field module, which automatically generates a static file on our server.

The firewall config means that this error was produced

Warning: file_put_contents(temporary://fileTjnJTX): failed to open stream:      "DrupalTemporaryStreamWrapper::stream_open" call failed in      file_unmanaged_save_data() (line 1898 of /var/www/user/includes/file.inc).
The file could not be created.


When editing and saving the content drupal tries to regenerate the image if none is available Our sysadmin is working the firewall configuration to allow the connections, but we was wondering if there is any easy way/drush commands/mysql statment to update all content,
You can take a look inside the module Drush Entity because in this module you have the command entity-update:

drush @drupal.d7 entity-update node 53 --fields=title


If you want to improve the command to work in all nodes you can read this post:
