Explanation
The terraform fmt command is used to rewrite Terraform configuration files to a canonical format and style.
This command applies a subset of the Terrra Terraform language style conventions, along with other minor adjustments for readability.

Explanation
Use the terraform providers command to view the specified version constraints for all providers used in the current configuration.

Explanation
API and CLI access are managed with API tokens, which can be generated in the Terraform Cloud UI. Each user can generate any number of personal API tokens, which allow access with their own identity and permissions. Organizations and teams can also generate tokens for automating tasks that aren't tied to an individual user.

Explanation
The terraform state command is used for advanced state management. Rather than modify the state directly, the terraform state commands can be used in many cases instead.
https://www.terraform.io/docs/commands/state/index.html

Each time a new provider is added to configuration -- either explicitly via a provider block or by adding a resource from that provider -- Terraform must initialize the provider before it can be used. Initialization downloads and installs the provider's plugin so that it can later be executed.
