[PATCH 2/3] virsh: qemu-monitor-command: Don't print extra newline with --pretty

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The prettified JSON string already contains a newline so don't print
another one. This allows to pipe the json output (in conjunction with
the --quiet option) to files without having to truncate them afterwards.
