Environment setup

It's convenient if the ROS environment variables are automatically added to your bash session every time a new shell is launched:

echo "source /opt/ros/kinetic/setup.bash" >> ~/.bashrc
source ~/.bashrc

If you have more than one ROS distribution installed, ~/.bashrc must only source the setup.bash for the version you are currently using.

If you just want to change the environment of your current shell, instead of the above you can type:

source /opt/ros/kinetic/setup.bash

If you use zsh instead of bash you need to run the following commands to set up your shell:

echo "source /opt/ros/kinetic/setup.zsh" >> ~/.zshrc
source ~/.zshrc
