Hello,

using, mellodic, just to setup things in a proper manner, where do I setup ROS variables for good?

I noticed my /etc/environement file was empty, so where do we setup ROS env variables ?

I checked them, there are 8 env variables defined so I guess, there must be some other place to set them ?

I checked setup.sh, but it's not in there

I could use ./bashrc, but it's not a boot setup, more like a terminal settings

details :

the idea is to set ROS_MASTER_URI on slave computers, I don't want these to be reset when I reboot them so, what's the best practice?

this tutorial only uses the (afaik volatile) EXPORT command : http://wiki.ros.org/ROS/Tutorials/Mul...

thanks

Could you please describe what you really want to do (instead of a potential solution for a problem we don't know)? I ask because there are ways to start ROS nodes "at boot" for instance that would either take care of this, or don't need you to go messing with files in /etc.

It's not a good idea to "setup ROS variables for good", as they may need to change, which embedding them in some file external to managed ROS packages/contexts will make impossible.
