You can pipe the json through jq.

> # lxc list --format table -c n

> When i try to use json format i see that useful fields like container name
> are missing in output. May be it will be useful to implement feature like:
>
> # lxc list --format raw -c n --no-header
> mysql-rep1
> mysql-rep2
> mysql-rep3
>
> The second feature looks useful is ability run commands on multiplie
> containers simultaneously. For example:
>
> # lxc exec web-node* -- apt update
>
> What do you think about it?
