'Batch' run a list and pipe it to email???

Is it possible to schedule a list view from CRON, and pipe the output to an email somehow from within CB?
I have a list I need to get out of the system, before we unsubscribe members, and this year we forgot, so we had to do a lot of manual work, it would be cool to just make a CRON job that did this the day before the unsubscribe process goes ahead.

Can you be more specific as to what you mean by pipe it to email. You want to take the results of a userlist and email it? results of a database query and email it? There's basically little you can't do with CB Auto Actions so a CRON endpoint is certainly doable, but it depends on your coding ability as you likely need to use a Code action to do all this. You can probably also setup mailers in CBSubs Mailer (CC or BCC) or emails using CBSubs Emails to be sent to you before a user is expired.

I know with the AutoActions, it's seriously the best invention since the wheel
But yes, my hope was that I could somehow take the output from a user-list, and send it as an email, and have it triggered by a CRON.
As a volunteer driven club we have a few yearly reportings we have to make regarding members, but it's important that these numbers are reported at the correct time, and this year we forgot to pull the list at the right time, so the numbers were wrong.
I don't have CBSubs, our diving club is very small, and we can't afford that.
My coding capabilities are so-so, I have done a few forms with PHP that calls CB functions, but that's about the gist of it.
The 'list' is actually made in an article, and consists of 6 CB lists, combined into one.
The lists are called with the "Components Anywhere" from Regular Labs.
My first attempt was to create a newsletter, and add the article to that, but the "components anywhere" plugin is not triggered to create the lists.

Without strong PHP ability it won't be possible to do that. A trigger does exist for userlists that gives you the array of users found, but you need to code looping them and creating an email body from all of that. CB Auto Actions can loop them, but it's going to send an email per user and I suspect that's not what you're wanting. Have you tried using something like AcyMailing to send a newsletter as it should have the ability to parse through Joomla content prepare plugins.

Unfortunately the 'Component Anywhere' can't be triggered from within Acymailing, and I'm not sure if there are other ways to place a CB list in an article?

You could try using an iframe I suppose, but that's not a snapshot of your userlist. That'd just be your userlist rendering in the email if the email doesn't get blocked due to having an iframe.
