Docker delete all images script not working on Ubuntu

I need your help with a command I was using on Windows but on Ubuntu it won’t work for me.

docker images | grep none | awk ' { print $3; } ' | xargs docker rmi -f & cls & docker images

With this command I get:

-bash: syntax error near unexpected token `}' as error.
cls is an alias I'm using and it's working`

Answer

Okay so I got it working with:

docker images | grep none | awk " { print $3; } " | xargs docker rmi -f ; clear ; docker images

Thanks for your efforts tho, it helped me with other problems 🙂
