def prepare
  # Running the prepare command, so make sure the timestamp is updated
  runner.update_last_prepared_at

  # Display the exact command syntax that's being run. This can come in handy if there's an
  # issue and the command can be copied/pasted or if the generated command somehow has some
  # incorrect syntax or options that need to be corrected.
  runner.output.current_command(runner.prepare_command)

  # Add a divider to visually delineate the results
  runner.output.divider

  # Run the command through the shell directly so no output is suppressed
