  The `pulsar` tool is used to start Pulsar components, such as [bookies](#pulsar-bookie) and [ZooKeeper](#pulsar-zookeeper), in the foreground.

  These processes can also be started in the background, using [nohup](https://en.wikipedia.org/wiki/Nohup), using the [`pulsar-daemon`](#pulsar-daemon) tool, which has the same command interface as `pulsar`.

  pulsar broker \
