# Command: agent
|
|
|
|
The agent command is the heart of Nomad: it runs the agent that handles client
|
|
or server functionality, including exposing interfaces for client consumption
|
|
and running jobs.
|
|
|
|
Due to the power and flexibility of this command, the Nomad agent is documented
|
|
in its own section. See the [Nomad Agent](/guides/operations/agent/index.html)
|
|
guide and the [Configuration](/docs/configuration/index.html) documentation section for
|
|
more information on how to use this command and the options it has.
|
|
|
|
