== Find Daemons

If you have installed the Java Development Kit (JDK), you can view live daemons with the `jps` command.

----
$ jps

----
33920 Jps
27171 GradleDaemon
22792
----

Live Daemons appear under the name `GradleDaemon`.
Because this command uses the JDK, you can view Daemons running any version of Gradle.
