I know that ansible can not show realtime output of commands to user consle.
https://github.com/ansible/ansible/issues/3887
But I want to see realtime output of commands.
@bcoca suggested me about ansible log.
https://github.com/ansible/ansible/issues/11233
I tried.
But ansible log is not realtime and does not contain output.
We must see shell comands, stdout and stderr.
I hope ansible will support server side commands log.
Please imagine user who is new to Linux.
The user never see commands, stdout and stderr in ansible world.
That is not good.
