What command should you run to display all workspaces for the current configuration?

To display all workspaces for the current configuration in Terraform, the command to use is "terraform workspace list." This command provides a straightforward way to view all the existing workspaces associated with the Terraform configuration you are currently working on.

In Terraform, workspaces allow you to have multiple instances of your infrastructure managed within a single directory, which can be helpful for managing different stages of development, such as staging and production environments. By running "terraform workspace list," you are effectively querying Terraform to provide a list of all the available workspaces along with indicating the currently active workspace.

Other commands such as "terraform list workspaces" and "terraform show workspaces" do not exist within the Terraform CLI, which is why they are not valid choices. Similarly, "terraform workspace show" displays information about the current active workspace but does not provide a list of all the workspaces. Thus, the most appropriate and effective command for this purpose is "terraform workspace list."
