Is this feature looks useful?
We've had some requests for it before and do support passing multiple container names for most non-interactive commands (start, stop, delete, ...). Passing wildcards is a bit annoying because you need to escape them in your shell for them to work out, I seem to remember they also believe kinda weird on Windows (where our client does work), but I'm not otherwise opposed to them if someone can find a sane, multi-platform way to have them without causing other regressions. For exec, the problem will be the mixed output you'd get from all the containers running the commands at the same time, with effectively the same terminal attached to them. > > > чт, 10 нояб. 2016 г. в 15:25, Stéphane Graber <stgra...@ubuntu.com>: > > > stgraber@castiana:~$ lxc list --format=json | jq .[].name > > "android" > > "lxd" > > "snapcraft" > > "test" > > "ubuntu-core" > > "ubuntu-zesty" > > "xen" > > "yak" > > > > On Thu, Nov 10, 2016 at 12:31:01PM +0000, Andriy Tovstik wrote: > > > Hi, Janjaap Bos! > > > > > > I tried jq.
