Solution to "unknown shorthand flag a in -a" When Trying to Remove Docker Containers

1 min read
docker

This docker command will remove all stopped containers.

Terminal window
docker rm $(docker ps -a -q)


```text


This docker command will remove all containers, even if they are running.


```bash


docker rm $(docker ps -a -q) -f


```text


If you run this command in a regular Windows Command prompt you will get the following output:


```bash


C:\>docker rm $(docker ps -a -q)
unknown shorthand flag: 'a' in -a
See 'docker rm --help'.

The solution is to run this command in a PowerShell terminal or the Docker QuickStart Terminal.
