RudiC,
This works perfectly:

Code:
$ docker image ls | awk 'NR==1 {print; next} {print | "sort -Vrk5"}'
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
linode/lamp         latest              2359fa12fded        4 years ago         372MB
centos              latest              9f38484d220f        3 months ago        202MB
ubuntu              xenial              13c9f1285025        6 days ago          119MB
ubuntu              latest              4c108a37151f        6 days ago          64.2MB
alpine              latest              4d90542f0623        5 days ago          5.58MB

Is there any way to use command chaining like I used previously for this example? i.e. multiple redirections.
