Usage: actionlint [FLAGS] [FILES...] [-]

  actionlint is a linter for GitHub Actions workflow files.

  To check all YAML files in current repository, just run actionlint without
  arguments. It automatically finds the nearest '.github/workflows' directory:

    $ actionlint

  To check specific files, pass the file paths as arguments:

    $ actionlint file1.yaml file2.yaml

  To check content which is not saved in file yet (e.g. output from some
  command), pass - argument. It reads stdin and checks it as workflow file:

    $ actionlint -

  To serialize errors into JSON, use -format option. It allows to format error
  messages flexibly with Go template syntax.

    $ actionlint -format '{{json .}}'
