### Remove all stopped containers
```bash
$ docker rm $(docker ps -a -q)
Use the [`docker container prune`](container_prune.md) command to remove all
stopped containers, or refer to the [`docker system prune`](system_prune.md)
command to remove unused containers in addition to other Docker resources, such
as (unused) images and networks.
Alternatively, you can use the `docker ps` with the `-q` / `--quiet` option to
generate a list of container IDs to remove, and use that list as argument for
the `docker rm` command.
Combining commands can be more flexible, but is less portable as it depends
on features provided by the shell, and the exact syntax may differ depending on
what shell is used. To use this approach on Windows, consider using PowerShell
or Bash.
The example below uses `docker ps -q` to print the IDs of all containers that
have exited (`--filter status=exited`), and removes those containers with
the `docker rm` command:
```console
$ docker rm $(docker ps --filter status=exited -q)
```
This command deletes all stopped containers. The command
`docker ps -a -q` above returns all existing container IDs and passes them to
the `rm` command which deletes them. Running containers are not deleted.
Or, using the `xargs` Linux utility;
```console
$ docker ps --filter status=exited -q | xargs docker rm
```
