[Unix] Abbreviation for `Read The Fucking Manual'.
1. Used by {guru}s to brush off questions they consider trivial or
annoying. Compare {Don't do that then!}.
2. Used when reporting a problem to indicate that you aren't just
asking out of {randomness}. "No, I can't figure out how to interface
Unix to my toaster, and yes, I have RTFM." Unlike sense 1, this use
is considered polite. See also {FM}, {RTFAQ}, {RTFB}, {RTFS}, {STFW},
{RTM}, all of which mutated from RTFM, and compare {UTSL}.
