I'm pretty sure chances are much higher that you get the data correctly if you reuse the settings and only change the filename, than reading the file as if it were completely new. If we want to refine it a bit, we could possibly distinguish:

I also thought the reason to load a datasource with an .kst file is to use the configuration saved in the kst file.
Otherwise we have no way to pass the configuration by command line. And in general it is not possible to make the
default for datasources good enough that it could read all data.

Is there any good example for using the -F option Barth's way? Maybe I've missed it.

But even when wanna read the configuration from the kst file we have to think
about the matching rules. What when we wanna load multiple datasources?

Or should be introduce a completely different way of configuring the datasource
by command line?

The advantage of using a kst file is that we already have a UI for editing.
