I want to use an existing launch file, but I want to run it while overiding every nodes log level with error. Something like

roslaunch --loglevel=error my_package my_launch.launch

I wrote an issue on exactly this, see

It should be possible to declare a launch argument in your launch file and then pass in to the nodes as arguments, see this answer.

Edit: Nevermind, I just realized you were talking about ROS 1. Keeping this answer in case someone is looking for the same issue for ROS 2.
