thats actually my first awk script.. so ye.. if you have some feedback.. i'd be happy 😄

its linked to this issue: moby/moby#7477

@GottZ remove sudo. You can run sudo usermod -aG docker $your_user so you don't have to run sudo with docker

i wrote this on the fly and didn't think about that. thanks!

adding this to my dotfiles, thanks @GottZ

Just found this. I have something similar where my focus is just to reduce the columns and sort the results by name.

  docker ps -a --format "table {{.Names}}\t{{.Image}}\t{{.Status}}\t{{.Ports}}" \
     | awk 'NR == 1; NR > 1 { print $0 | "sort" }'

Recently had encountered multiple port bindings for a container so just piped my result to your awk script. Thanks!

Following on from @lemonkoala's lead I wrote a small bash script to do the messy stuff. It takes a list of options (e.g. -iIcClmnNprSshL), constructs the go string and invokes the docker ps with it. In case its useful to anyone its here:

screenshot for reference.. cause apparently it helps explaining what this script does.
