# Command-Line: Validate
|
|
|
|
|
|
|
|
|
|
The `packer validate` command is used to validate the syntax and configuration
|
|
|
|
|
of a [template](/docs/templates/introduction.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:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ packer validate my-template.json
|
|
|
|
|
