How to query the map offline, on Linux? (feddit.uk)

I like searching for POIs via a query language on Overpass. My queries tend to be quite simple - "get all amenities of x type, in y area that have z tag". The rendered map showing matching POIs is a nice-to-have, but not completely necessary.

What is the best way to do this offline, on Linux? (ideally using software already packaged for Debian, but that's not vital).

I'm imagining a REPL that I can pass a downloaded map to, and then can query and see the results (in an ideal world, rendering them too).

It seems database schemas are close to what I want, but they seem to be designed more for people doing large scale complex queries and building bespoke databases just with the information they want.

Are these tools a good fit for my use case, or is there is a better/simpler way?

Can osmium-tool do what you want?

For example if I go here and export an osm file as pittsburg.osm: https://www.openstreetmap.org/export#map=18%2F40.440748%2F-79.999822

Then I run osmium tags-filter pittsburg.osm n/amenity=library -o out.osm

I get an out.osm with a bunch of libraries in it:

<?xml version='1.0' encoding='UTF-8'?>
