Hello Konstantin,
I wonder if it would be more useful to add '-n, --lines=[+]NUM' that
would be similar
to tail(1) option and argument. The --follow-new with an option that
lists NUM last
messages would be --lines=0
That said should --since and --until options similar to journalctl(1)
be considered
as well?
