title: How do I specify a single file to be seed only
body: <p>I am using knex for seeding and I have a folder called development where I have all the seeds files.</p>
  
  <p>What I would want is: How to seed single file.</p>
  
  <p>The command I am using is: knex seed:run --env=development
  But this command is to seed all the files and I get duplicate rows on db.</p>
  
  <p>Suppose I have created seed files yesterday, and I seed them, today I want to add another seed file, which I only want to seed this file, not the files from yesterday.</p>
  
  <p>An example from Laravel is: php artisan db:seed --class=ProductTableSeeder</p>
  
  <p>Thanks</p>
