In Ubuntu, how do I authenticate to trigger a Jenkins job remotely using the CLI?

Question

As far as I understand, using the Linux CLI, builds can be triggered remotely using the curl command and the following URL syntax:

<JENKINS_URL>/job/<JOB_NAME>/build?token=<TOKEN_NAME>

Example:

$ curl http://localhost:8080/job/MyJob/build?token=my-token

However, when I run the command, I receive the following:

Authentication required
<!--

</body></html>

Is authentication done using the CLI or the Jenkins web interface? How do I authenticate?

This is covered in the documentation. In short, if you are triggering via HTTP, you need to generate an authentication token and use it with HTTP Basic auth, for instance:

curl -X POST -L --user your-user-name:apiToken https://jenkins.example.com/job/your_job/build
