Merci Moritz,

I tested already (before asking)

env = os.environ.copy()
if list_only:
   env['GRASS_VERBOSE'] = '3'

but it does not work.


It shouldn't, you copied the environment, you didn't change the environment
used. You would have to take the copied env and pass it to run_command,
then it would work. Or of course, modify the actual environment, not the
copied one. Hope this clarifies it a bit.

Aren't there other ways?

Thank you again, N
