Smenu, a command-line advanced selection filter and a menu builder for terminal
This is like dmenu but it stays in the terminal. I've needed something like this in the past before for some scripts. Neat.
I've been happily using vis-menu which is a fork of slmenu which is a terminal version of dmenu: http://martanne.github.io/vis/man/vis-menu.1.html
vis-menu is distributed with vis: https://github.com/martanne/vis
This project seems fine as well; though the examples seemed a bit complicated to me. I guess I'll need to rtfm.
