considering a vector map, do you know a simple way to perform multiple

Thank you Markus,
I tried several methods like d.extract, or
d.where | v.what map=zonpi test and extracting cat values from the
test file. Now I am wondering if it is worth (let's better say realistic
given my skills) to try and write a custom module, inspired from
v.digatt.

Very much related to this, please see my suggestions for updates to
the GRASS query functions. Most should be relatively minor changes,
but would make querying much easier. And it would make it easier to
implement GUI wrappers for interactive querying.

Yes. That's the idea. Martin Landa already has tried to implement this
to some extent in the new wxPython GUI. But it involves a lot of
workarounds for inadequacies in the GRASS vector querying. These
updates to querying modules would make this easier and more robust.

Nice,
