This is separate from [your infrastructure configuration](/docs/configuration/index.html), and provides per-user customization that applies regardless of which working directory Terraform is being applied to. For example, the CLI configuration file can be used to activate a shared plugin cache directory that allows provider plugins to be shared between different working directories, as described in more detail below. The configuration is placed in a single file whose location depends on the host operating system: * On Windows, the file must be named named `terraform.rc` and placed in the relevant user's "Application Data" directory. The physical location of this directory depends on your Windows version and system configuration; use `$env:APPDATA` in PowerShell to find its location on your system. * On all other systems, the file must be named `.terraformrc` (note the leading period) and placed directly in the home directory of the relevant user. On Windows, beware of Windows Explorer's default behavior of hiding filename extensions. Terraform will not recognize a file named `terraform.rc.txt` as a CLI configuration file, even though Windows Explorer may _display_ its name as just `terraform.rc`. Use `dir` from PowerShell or Command Prompt to confirm the filename. ## Configuration File Syntax The configuration file uses the same _HCL_ syntax as `.tf` files, but with different attributes and blocks. The following example illustrates the general syntax; see the following section for information on the meaning of each of these settings: ```hcl plugin_cache_dir = "$HOME/.terraform.d/plugin-cache" disable_checkpoint = true ``` ## Available Settings The following settings can be set in the CLI configuration file: * `disable_checkpoint` - when set to `true`, disables [upgrade and security bulletin checks](/docs/commands/index.html#upgrade-and-security-bulletin-checks) that require reaching out to HashiCorp-provided network services. * `disable_checkpoint_signature` - when set to `true`, allows the upgrade and security bulletin checks described above but disables the use of an anonymous id used to de-duplicate warning messages. * `plugin_cache_dir` - enables [plugin caching](/docs/configuration/providers.html#provider-plugin-cache) and specifies, as a string, the location of the plugin cache directory. ## Deprecated Settings The following settings are supported for backward compatibility but are no longer recommended for use: * `providers` - a configuration block that allows specifying the locations of specific plugins for each named provider. This mechanism is deprecated because it is unable to specify a version number for each plugin, and thus it does not co-operate with the plugin versioning mechansim. Instead, place the plugin executable files in [the third-party plugins directory](/docs/configuration/providers.html#third-party-plugins).
