docker run reporting an error for port mapping

I have installed Docker Desktop for Mac and I'm trying to run Jenkins in a docker container.

When I attempt to run the following command:

docker run --name jenkinsci -p 8080:8080 jenkins/jenkins:lts

the following error is reported:

unknown shorthand flag: 'p' in -p

I've been through Get started with Docker Desktop for Mac successfully so I know docker is working correctly.

Docker version details:

It seems that somehow a non-space character got in between run and --name. I copied the string from a web page.

The above command does in fact work ok.

You need to stop the running container before you change the port. You can see a quite similar post: Docker doesn't recognize the -p command all of a sudden
