Hello guys,
for example in navigation process, you run more roslaunch command. After every command some news Topics are added. My question is, how to see just topics related to specific roslaunch file ?

Thanks for answer Best Regards Peter Tomašovič

The best way to do that would be:

  • in the launch files, create new topics with some prefix or suffix.
  • run rostopic list | grep 'your-prefix'.

If you can’t modify the launch file in some way, or the topics don’t have a pattern, I don’t know of any other way.
