# 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-docs/catalog).
|
|
|
|

```shell-session

|
|

|
|
dc2
|
|
dc3
|
|
```
|
|
