Explain with highlit
Management commands are perfect for scripts that need Django's ORM and settings. I create them in management/commands/ and extend BaseCommand. The add_arguments method defines CLI options using argparse. I use self.stdout.write with style helpers for colored output. For long-running imports, I show progress and handle errors gracefully with try-except. Commands are testable with call_command() and can be scheduled with cron or Celery beat. This keeps admin scripts organized and discoverable via ./manage.py help.
