I have used the split command (here on OS X) to split those down to more manageable sized (about 10 MB each) Sure, this will create a lot of files. What I want JTR to do is to be able to load each list in turn during the same session to process against hashes I have.

JtR doesn't support use of multiple wordlist files in one session.
We might or might not add this feature later.

Meanwhile, you could work around this with commands like:

cat *.txt | ./john --stdin ...

or using "--pipe" in place of "--stdin".

However, I don't recommend this.  What I recommend is that you simply
avoid generating wordlists this large.  Especially not if you also
intend to edit them (why would you?!)  Use a smaller wordlist, and use
JtR's wordlist rules, etc. to modify and extend it on the fly as needed.

I understand that with pre-applied rules you can filter out duplicates
(such as with our "./unique" program), which is about the only valid use
case for such large wordlists.  If that's what you do, you should have
no need to edit the resulting wordlist.

Having a large generated wordlist _and_ wanting to edit it indicates
that you need to take a step back, and reconsider what you're doing.

IIRC, at some point in the past you mentioned you were using Crunch,
but perhaps you don't anymore?  There's no valid use case for Crunch
along with JtR as we have equivalent or better functionality built in.

I hope this helps.
