2013-05-23 05:34:23 -0500 commented question How to get the graph resource name for a node?

I updated the question and provided an example. I can sum up the question as: Is there a way to find out the default node name and topic names before launching the node?

Hi, After launching a node, I can get its graph resource name using the rosnode info /node_name command line. Is there a way to get this information Before launching the node?

As an example, suppose that I want info about turtlesim_node. Currently, I have first to run it rosrun turtlesim turtlesim_node

Then I have to find out some how what is the name of the node I'm interested in, for example by using: rosnode list This will show me all running nodes. Knowing the previous list of running nodes, I can deduce that the new node is named /turtlesim. This way of doing it already annoys me. Is there a simpler way?

And once I have found the node name, I have still to use the rosnode command to have topics published and subscribed by my node rosnode info /turtlesim Again, this is heavy.

I wonder if I can have the names directly from the turtlesim package without launching turtlesim_node?

Thanks
