Drush provides an API that allows developers to write their own commands. These commands can be part of a module and loaded through a Drupal installation, or they can be placed in the local user's Drush folder for general purposes.
Often, contributed modules create commands to automate user interface operations. However, creating a custom Drush command can be useful for specific operations. In this recipe, we will create a command that loads all the users who have not logged in in the last 10 days and resets their password.
