You’ve installed JBang.
You have executed the following command:

jbang app install camel@apache/camel

Supposing you have a file named route.yaml with this content:

- route:
    from:
      uri: "kamelet:timer-source"
      parameters:
        period: 10000
        message: 'test'

        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml
