2016-05-31 11:31:52 -0500 commented answer How to find list of messages published on particular topic?

@ Mark : Yes, but I want to know the name by which the message is published, if I use rostopic list it shows sensor_msgs//LaserScan not name of the message ("scan").

2016-05-31 10:38:22 -0500 asked a question How to find list of messages published on particular topic?

I am using turtlebot in gazebo which uses "scan" message for publishing laser scan data, by using rostopic type scan command I can find out type of the message i.e. sensor_msgs/LaserScan , Is there way to find names of all the messages published on particular topic ?

For example, Is there any way to find out that message named "scan" is published by turtlebot knowing only the topic name i.e. sensor_msgs/LaserScan ?

Thanks in advance.

2016-05-23 12:00:32 -0500 asked a question Error in running "sudo rosdep init"

I had previously installed ROS Jade distribution, I have uninstalled it and trying to install Indigo, while running sudo rosdep init I get following error :

ERROR: default sources list file already exists:
    /etc/ros/rosdep/sources.list.d/20-default.list
Please delete if you wish to re-initialize

As suggested in one of the answers I tried using sudo pip uninstall rosdep to uninstall previous version which gives sudo: pip: command not found

Is there any way to manually remove rosdep? running which rosdep gives me this /usr/bin/rosdep

I found this question on the same error
