# Consul Catalog
Command: `consul catalog`
The `catalog` command is used to interact with Consul's catalog via the command
line. It exposes top-level commands for reading and filtering data from the
registry.
The catalog is also accessible via the [HTTP API](/api/catalog).
## Basic Examples
List all datacenters:
```shell-session
$ consul catalog datacenters
dc1
dc2
dc3
```
List all nodes:
```shell-session
$ consul catalog nodes
Node ID Address DC
worker-01 1b662d97 10.4.5.31 dc1
```
List all nodes which provide a particular service:
```shell-session
$ consul catalog nodes -service=redis
Node ID Address DC
worker-01 1b662d97 10.4.5.31 dc1
worker-02 d407a592 10.4.4.158 dc1
```
List all services:
```shell-session
$ consul catalog services
consul
postgresql
redis
```
List all services on a node:
```shell-session
$ consul catalog services -node=worker-01
consul
postgres
```
