I would like to output paraview logs to a file, but without them appearing in standard out. Is this possible?

I tried something like this, but I get the logs in both in the terminal and the file:

```auto
env PARAVIEW_LOG_PIPELINE_VERBOSITY=INFO /usr/local/opt/paraview_egl/bin/pvbatch -l /tmp/pvlogs

```

You can set the verbosity of each log file as well as the standard output separately. The `-l`/`--log` option allows you to add a `,` after the filename followed by a log level. Likewise, the `-v`/`--verbosity` option sets the log level for the standard output but not the log files.

```bash
env PARAVIEW_LOG_PIPELINE_VERBOSITY=INFO \
  /usr/local/opt/paraview_egl/bin/pvbatch \
    --log /tmp/pvlogs,INFO --verbosity WARNING \
    myscript.py

```
