Sorry, I guess this is probably more what you're after:
```console
$ docker ps -h

Usage: docker ps [OPTIONS]

List containers

  -a, --all=false: Show all containers. Only running containers are shown by default.
  --before="": Show only container created before Id or Name, include non-running ones.
  -l, --latest=false: Show only the latest created container, include non-running ones.
  -n=-1: Show n last created containers, include non-running ones.

  -q, --quiet=false: Only display numeric IDs
  -s, --size=false: Display sizes

```
