Perhaps I missed the full name somewhere in the thread, but what is TFA?

Sibling comment got the definition, but “TFA” comes from “RTFA”: “read the fucking article”, in response to “yeah, but what about ($THING that was discussed at length in the first paragraph)?”

Origins: “RTFM”. “What’s the switch for ls that prints time stamps?”

“Read the fucking manual.”

The fucking article. Or you could imagine a more polite alternative.
