[lxc-users] Feature request: raw lxc utilities output format and operations with multiplie containers?

[Andriy Tovstik]

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?
