What subcommand would you use to list all resources in the Terraform state?

Using the subcommand to list all resources in the Terraform state is essential for managing and understanding your infrastructure. The correct choice allows you to inspect the resources currently tracked in the Terraform state file, providing insights into what resources have been created, their dependencies, and how they correlate with the configurations in Terraform code.

The command specifically designed for this purpose is 'terraform state list'. When executed, it will display all the resources that Terraform is currently managing in the state file, which is crucial for performing any updates, modifications, or troubleshooting during infrastructure management. This command helps ensure that you are aware of all the components within your environment, which is particularly valuable when working in teams or managing complex architectures.

In contrast, other options either represent commands that do not exist in Terraform or serve different purposes. For example, 'terraform show' provides a detailed view of the resource state but does not list them as succinctly as 'terraform state list'. Similarly, 'terraform list' is not a command available in Terraform's offering, and 'terraform resources' is not a recognized command in the context of managing Terraform states. Thus, 'terraform state list' is the appropriate and accurate command for listing resources in the Terraform state.
