No, a job is the "template", an invocation of the job is a "build". The appropriate link in Jenkins is "Build Now", and you can also go "Next Build" or "Previous Build". In fact, I think a link to the build, or at least the build number, should be the output of this task, but getting that via the CLI seems to be non-trivial...
