Disable any output of roscore

I have already seen many threads addressing this topic, but they seem to be slightly different. I am working on melodic and Ubuntu 18.04.

What I have tried so far:

  • set log4j.threshold=OFF in rosconsole.config
  • set export ROSOUT_DISABLE_FILE_LOGGING=True in .bashrc
  • set ' param name="/rosout/omit_topics" value="true" ' in the launchfile

This does indeed turn of any INFO/WARN/ERROR but keeps the summary at the very beginning, when launching the roscore/launchfile. I need to be able to call

roscore

without any output in the screen. Ideally not even process[xyz]: starting or killing on exit output. The reason is, that I start and restart multiple instances, which basically makes my own logging disappear in a bunch of rosoutput.

Cheers

For now I went with the ugly way and modified some files in

/opt/ros/melodic/lib/python2.7/dist-packages/roslaunch/

The summary is printed in parent.py and most of the other stuff by the functions printlog() and printlog_bold() in core.py. The rest is found in launch.py and __init__.py.

Anyway I will leave this post open, since the solution is not pretty and applies to all the nodes running on the computer.
Would be nice if someone has a better solution, even though the code does not look like as hiding the summary by config file is considered.

Cheers
