Yep!
nice idea, boys! moreover i can use -r switch with jq. But
unfortunately your solution can't execute tasks in parallel ;)

Andriy, (meanwhile) you can help yourself with (doing that
sequentially)..
for container in `lxc list mysql-rep --format=json | jq .[].name |
tr -d '"'`; do lxc exec $container -- apt update; done

Thanks, Stéphane, i'm very inattentive... Now it looks better.
Additional output format seems to be more comfortable than
additional tools. But it insignificantly.
And what do you think about the second question about ability to
run commands on multiplie containers simultaneously using regexps
as container name ? Is this feature looks useful?
