Which command saves the execution plan to a file?

The command that saves the execution plan to a file is accurately represented by the option that uses the -out=FILE flag. When you run terraform plan -out=FILE, Terraform generates an execution plan based on your current infrastructure and the configuration files provided. This command creates a file containing the plan so that it can later be applied using the terraform apply command with the -input=false flag to ensure that the standard input is not required.

By saving the execution plan to a file, you can share it with stakeholders, review it before applying changes, or stage it for an appropriate time to apply the changes, which is a critical aspect of managing infrastructure as code effectively. This built-in capability helps ensure that the exact changes can be validated and reviewed before being executed, adding a layer of safety and predictability to the deployment process.
