In this tutorial, we are going learn how to create\/update nodes with the help of the Drush command using\u00a0 Batch API in Drupal. For that, we need to create a custom module. The file structure will be like below:<\/p>\n

Example: In the below example, we are updating the article content type Title<\/strong> field with a dummy value by dividing it into chunks of 100, similarly can add your own logic.<\/p>\n

To create a custom module, follow the below steps, which will help create a custom Drush Command update:node article.<\/strong><\/p>\n

    \n
  1. Create BatchDrushCommand.php<\/em> file under the custom module\/Commands folder.<\/strong>\n

    Once the code is added to the module, enable the module or if you are using the existing module, then clear the drupal cache and run the drush update:node article
