> Yes, but termcap/terminfo are about output, not input. Termcap itself--the older system of the two, and the one that's mostly subsumed by terminfo nowadays--supports input-related features already! See e.g. https://www.gnu.org/software/termutils/manual/termcap-1.3/html_mono/termcap.html#SEC37 https://www.gnu.org/software/termutils/manual/termcap-1.3/ht... Anyway, surely some sort of keyboard raw input exists already, if only so that X can use it? AIUI, X does run without root privileges these days, and keyboard input was never the main obstacle to X running without root - video output was. So, I think the article is not quite right in its assumption that detecting raw keyboard events necessarily involves root-level access.
