Suppress error message from sh for background process

[Ivan Ogasawara]

Hey everyone!

Is there a way to suppress the error message from sh for background process?

if there is an error message from the process, this is something I want to show/print .. but not from the sh python traceback, for example, this is something that I don't want to show:

Exception in thread background thread for pid 323610:
Traceback (most recent call last):
  File "/home/xmn/mambaforge/envs/makim/lib/python3.10/threading.py", line 1016, in _bootstrap_inner
    self.run()

    self._target(*self._args, **self._kwargs)

    raise exc
sh.ErrorReturnCode_1: 

  RAN: /usr/bin/bash -c 'pre-commit run --all-files --verbose'

  STDOUT:


  STDERR:

additionally, I have already something like that:

        try:
            p.wait()
        except sh.ErrorReturnCode:
            ...
        except KeyboardInterrupt:
            pid = p.pid
            p.kill()
            print(f'[WW] Process {pid} killed.')
