# atmos terraform refresh

Use this command to refresh the Terraform state for an Atmos component in a stack, updating it to match the current remote infrastructure.

## Usage

Execute the `terraform refresh` command like this:

```shell
atmos terraform refresh <component> -s <stack> [options]
```

This command reads the current settings from all managed remote objects and updates the Terraform state to match. This won't modify your infrastructure but will update the state file.

:::info Atmos Enhancements
