Why wouldn't that work?

It would.

But whilst memory rather than speed was the focus; solutions that avoid writing millions of lines to a file; sorting (which itself re-reads and re-writes all those lines, often several times); and the re-reading them all again; are likely to be considerably faster. Hence my preference for an 'internal' solution.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
