[ros-users] [Discourse.ros.org] [Next Generation ROS] "rostopic" command for ROS2?

[刘杨]

Dear developers and users of ROS2,

here is another "naive" question from me:

Is there already some tools or APIs that can help me see the currently active Topics in an existing ROS2 network? Something like the `rostopic` command in ROS1?

thanks for any answer!
