# `validate` Command

The `packer validate` Packer command is used to validate the syntax and
configuration of a [template](/docs/templates/index.html). The command
will return a zero exit status on success, and a non-zero exit status on
failure. Additionally, if a template doesn't validate, any error messages will
be outputted.

Example usage:

``` text
$ packer validate my-template.json
Template validation failed. Errors are shown below.

Errors validating build 'vmware'. 1 error(s) occurred:

* Either a path or inline script must be specified.
```

## Options

-   `-syntax-only` - Only the syntax of the template is checked. The configuration
    is not validated.
