What is a common use of the `terraform output` command?

The terraform output command is primarily used to extract information from the outputs defined in a Terraform configuration. When variables or outputs are declared within a Terraform module or project, the terraform output command allows users to retrieve and display these output values in a clear format. This is especially useful for obtaining important information such as resource IDs, IP addresses, or other valuable data that can be used in further processes or referenced for manual operations.

For example, if a user has defined an output for a resource's public IP address, running terraform output can quickly provide that information without the need to dive into the state file manually. This command facilitates the interaction with the outputs and helps streamline workflows, particularly in larger infrastructure setups where such information is critical for subsequent resource provisioning or integration with other services.
