Help

The lint:yaml command lints a YAML file and outputs to STDOUT
the first encountered syntax error.

You can validates YAML contents passed from STDIN:

  cat filename | php bin/console lint:yaml -

You can also validate the syntax of a file:

  php bin/console lint:yaml filename

Or of a whole directory:

  php bin/console lint:yaml dirname
  php bin/console lint:yaml dirname --format=json

You can also exclude one or more specific files:

  php bin/console lint:yaml dirname --exclude="dirname/foo.yaml" --exclude="dirname/bar.yaml"

Or find all files in a bundle:

  php bin/console lint:yaml @AcmeDemoBundle
