> sudo docker network ls NETWORK ID NAME DRIVER SCOPE 9d7cdf93dc36 bridge bridge local b6cdfd5c05db host host local 2ab9a67af69b none null local 775c2de3694e poopcode-network-qa bridge local
We can filter the network using the filter argument.
> sudo docker network ls --filter driver=bridge NETWORK ID NAME DRIVER SCOPE 9d7cdf93dc36 bridge bridge local 775c2de3694e poopcode-network-qa bridge local
> sudo docker network ls --filter id=775c2de3694e NETWORK ID NAME DRIVER SCOPE 775c2de3694e poopcode-network-qa bridge local

We can format the result using the following format.
> sudo docker network ls --format "{{.ID}}-{{.Name}}-{{.Driver}}"
9d7c3f93dc36-bridge-bridge
b6cdad5c05db-host-host
2ab9a67af69b-none-null
