What is this line trying to achieve in the "Getting Started with a Real TurtleBot" Tutorial (Robotics Toolbox)?

sudo sh -c 'echo export ROS_HOSTNAME=IP_OF_TURTLEBOT >> /etc/ros/setup.sh'

I do not have a ros directory in /etc. My installation is in /opt.

Am I appending to an existing setup.sh (the one where my ros installation is), or am I creating a new setup.sh file?

Thanks.

It depends on your environment, but normally just appending the export command to your .bashrc in your home directory will work.
