'Betty is like Siri or Google Now for the command line. Well, sort of.
The tool translates plain English into commands: it displays the
command it runs and obviously, the command output, in the terminal.
Betty isn't voice controlled so you still have to type your (plain
English) commands but if you want, it can speak the command output.
Betty's mission is, according to its GitHub page, to "provide a way to
use computers through natural language input"'
