# atmos terraform version

Use this command to display the Terraform/OpenTofu version being used for an Atmos component in a stack.

:::info OpenTofu Support
When using OpenTofu, this command will display the OpenTofu version instead of Terraform version.
:::

## Usage

Execute the `terraform version` command like this:

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

This command displays the Terraform or OpenTofu version, along with the versions of installed providers.

:::info Atmos Behavior
This is a pure passthrough command. Atmos does not perform any special processing for `terraform version`. The command is executed directly without workspace management or variable generation.
:::
