Lauch sim_vehicle.py using PATH on .bashrc file

#1

In the video “Ardupilot Installation Part 1”, when you used “sudo vim ~./bashrc” to get edit the file. But I couldn’t see the section "#PATH=$(echo… " with all the exports to add PATH in there. When you got to the .bashrc file, it seemed like you cut it and got to a new file or you created that whole section.
Can you help me with this part?

Thank you

type pwd and copy the path, then go into the editor and add the path at the end

sudo vi ~/.bashrc
export PATH="(paste path here in quotes)":$PATH
