Exploring nodes
rosnode provides information about nodes that are alive:
$ rosnode list
This lists all the nodes of the current ROS graph. From the list, you can access information about any of them:
$ rosnode info distance_sensor
Here, info will provide you with useful information about the distance_sensor node. Do not confuse this with the name of the Python script where the node is declared, distance-sensor.py. The rosnode command always refers to the name of the node.
