What does it mean to source all?

Respected Sir,

  1. What does it mean to source ALL the webshells in the following pic

  2. Can the node name, rospy.init_node() , be anything?

Hello @abdulbasitisdost,

  1. When you compile your package in order to create a new message, you need to source the Web Shell in order to be able to use this new message. To source the Web Shell means to execute the following command:

source ~/catkin_ws/devel/setup.bash

  1. Yes, the node name can be anything you want.
