+## Using CLI pulsar clients 
+
+Pulsar provides a CLI tool called [`pulsar-client`](reference-cli-tools.md#pulsar-client) that enables you to do things like receive messages from a Pulsar topic in a running cluster. This command will receive a simple message saying `hello-pulsar` to the `my-topic` topic:

+```bash
+$ bin/pulsar-client consume my-topic -t Shared -s demo-sub -n 0

+
+```
+----- got message -----
+hello-pulsar
+```
