When running bin/rails -h the following messages is shown:
All commands can be run with -h (or --help) for more information.
This doesn't apply to the commands that are Rake tasks like db:migrate.
If you run bin/rails db:migrate -h you'll get the Rake help, which
can be confusing...
Instead, if we replace the -h argument with --describe db:migrate
Rails outputs the Rake task descriptions, which are a lot more helpful:
rails db:migrate
Migrate the database (options: VERSION=x, VERBOSE=false, SCOPE=blog).
