I need to merge List A into List B. My plan is to run list_members on both lists and use the Unix 'uniq' tool to find the members of List A who are not already in List B. Then I'll use the web interface's mass subscription page to add the members from List A to List B.
Depending on how lazy you want to be, I'm guessing you might be able to just take the member list from List A and mass subscribe it to List B.
I think Mailman would just complain about the people who are already subscribed to List B and then process the rest. Though I haven't tried this.
I tried playing around with uniq (and two dummy files) and it might do what you want but the results weren't intuitive to me.
I hacked together a script a few years ago to compare two files and say which lines are just in file A, just in file B, or in both; it's at http://blog.anthonyrthompson.com/listserv-to-mailman/code/utils/filecomplines
Following that, I'll run rmlist on List A without deleting its archives. However, ideally I'd like to make the archives of Lists A and B available in one place to all the members of the new expanded List B.
If it was me, I'd just remove all the subscribers from List A, add a dummy subscriber account set with delivery off and mod on, and then give out the dummy account and its password to the folks on List B for archive access.
