How to get only time stamp in a big topic in a command line
Because the size of a topic is quite big (like point cloud), the 'rostopic echo' command cannot show the time stamp in a terminal because of the scroll pressure and 'rqt' software freezes itself when 'topic monitor' is enabled for the topic.
So, how can we get only time stamp in a big topic by a command line in a terminal?

No, see the wiki documentation and therein the last documented function.
Actually, this is a duplicate of #q225849
