     9  # Command: validate
    10  
    11  The `terraform validate` command is used to validate the syntax of the terraform files.
    12  Terraform performs a syntax check on all the terraform files in the directory,
    13  and will display an error if any of the files doesn't validate.
    14  
    15  This command **does not** check formatting (e.g. tabs vs spaces, newlines, comments etc.).
    16  
    17  The following can be reported:
    18  
    19   * invalid [HCL](https://github.com/hashicorp/hcl) syntax (e.g. missing trailing quote or equal sign)
    20   * invalid HCL references (e.g. variable name or attribute which doesn't exist)
    21   * same `provider` declared multiple times
    22   * same `module` declared multiple times
    23   * same `resource` declared multiple times
    24   * invalid `module` name
    25   * interpolation used in places where it's unsupported
    26   	(e.g. `variable`, `depends_on`, `module.source`, `provider`)
    27   * missing value for a variable (none of `-var foo=...` flag,
    28     `-var-file=foo.vars` flag, `TF_VAR_foo` environment variable,
    29     `terraform.tfvars`, or default value in the configuration)
    30  
    31  ## Usage
    32  
    33  Usage: `terraform validate [options] [dir]`
    34  
    35  By default, `validate` requires no flags and looks in the current directory
    36  for the configurations.
    37  
    38  The command-line flags are all optional. The available flags are:
    39  
    40  * `-check-variables=true` - If set to true (default), the command will check
    41    whether all required variables have been specified.
    42  
    43  * `-no-color` - Disables output with coloring.
    44  
    45  * `-var 'foo=bar'` - Set a variable in the Terraform configuration. This flag
    46    can be set multiple times. Variable values are interpreted as
    47    [HCL](/docs/configuration/syntax.html#HCL), so list and map values can be
    48    specified via this flag.
    49  
    50  * `-var-file=foo` - Set variables in the Terraform configuration from
    51     a [variable file](/docs/configuration/variables.html#variable-files). If
    52    "terraform.tfvars" is present, it will be automatically loaded first. Any
    53    files specified by `-var-file` override any values in a "terraform.tfvars".
    54    This flag can be used multiple times.
