This is a continuation of Rejecting obvious questions? and Is it okay to ask questions here when Wikipedia already has the answer?.
We get the occasional question where the best answer is to refer the asker to Wikipedia or to a program's reference manual — RTFM questions.
A general reference close reason is currently under evaluation on two Stack Exchange sites, Science Fiction and Fantasy and English Language & usage. Being a regular on SF&F, I can report that we don't use it often, but it feels like a reasonable filter.
This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.
Do we want this close reason on Unix & Linux as well?
In the meantime, should we close questions such as What is a zombie process? as “too localized”, since the “this question is unlikely to ever help any future visitors”?
