How to get different data each time?

[pestevez]

I am trying to generate random posts every few minutes using a cron job but for the given file I always get the same post title and content:

Trendwerk\Faker\Entity\Post:
  post{1..1}:
    post_content: <paragraphs(4, true)>
    post_title: '<sentence()>'

this is how my command looks like:

wp faker fake post.yml

Is it possible to randomize the generated content each time the command is executed?

Thanks in advance for your help!
