2019-12-09 05:52:56 -0500	marked best answer	What does rosrun do internally? I was following this tutorial - https://wiki.ros.org/ROS/Tutorials/Wr... Out of curiosity, I ran the listener using `rosrun beginner_tutorials listener.py` but ran the talker manually. That is, I changed directory to beginner tutorials, and ran, `python talker.py`. I didn't expect it to work, but it did. The nodes are communicating with each other. Is that a fluke, or will this always work? Is rosrun's job only to find the correct node based on the ROS_PACKAGE_PATH, or does it do something else as well?
