I was pondering this and looking around as to whether an
existing command could get an option to support this as
I was a bit worried that a whole command was overkill.

Perhaps this new command could get more logic in future,
though I can't think of anything obvious at present. In any case
I don't like "core" in the name as there can be multiple
processing units per core. I vote for "nproc".

grep '^proc'

cheers,
