Yes, I downloaded the .sch and .pcb files, but I don't have the symbols
referred to in the .sch file.
I more or less follow your explanation about a hierarchical structure
and prefixes in the RefDeses to distinguish between schematic pages.
And yes, when I start a new project, I already use the strategy of using
RefDes 100+ for page 1 (or channel 1), 200+ for page 2 (or channel 2),
and so on; and RefDes in single and double digits are often used for
common, not too large circuits, e.g. supply circuits and other common
stuff.
However, I don't quite understand how this applies to the current
situation here, where I have one project with several existing gschem
pages, with RefDes numbering all over the place.

I don't particularly want subpages or Refdeses with prefixes, but just a
way to find the next free global RefDes for any component, without
changing the gschem files themselves.I also don't understand what role
PCB plays in this. The whole point is that at the moment, duplicate
RefDeses only show up when importing everything in PCB, and I want to
prevent this by checking just gschem files.
I really appreciate the time you took to come up with all these bash
commands to process gschem and PCB files, but to me it does not look all
that simple. Maybe we're not quite on the same (gschem) page here (to
use an appropriate metaphor...)?

This sounds more like what I'm looking for, but I thought about it, and
it should be pretty easy to write a script that concatenates and sorts
all gschem files listed in a project file, and then tries matching a
counter to RefDes numbers for each component type, and simply spits out
the counter values for which no RefDes is found.

Sorry, once again you lost me. What does the above do exactly? I really
think we have some sort of misunderstanding here. I'm not looking for
lists of existing components or component attributes, nor do I want to
convert gschem pages to a hierarchical structure; I'm just looking for
the first unused Refdes for a particular component type over multiple
gschem files. So something that works like this, assuming that C121,
C133 and R89 are unused so far:
$ nextcomp C
C121
[-> entered a new capacitor C121 in one of the gschem files, saved it]
$ nextcomp C
C133
[-> entered C133, saved file]
$ nextcomp R
R89
(etcetera)
> My guess is that your program doesn't provide anything new.
So far, I can't find anything that does what I'm looking for, at least
in a simple way as given above. I shall build this script of mine, and
if you like, I can post the result here.
So thanks again for your replies, your code and for trying to think
alone, I really appreciate the effort!
Regards,
Richard
