I've been working on a Linux CLI poker odds calculator. It's early days, at the moment it only does 2-handed odds, pre-flop, post-flop and post-turn. It's released under the GPL, source code is available at https://github.com/stridervc/PokerEV

Comments, feedback and patches welcome

Thanks for this, always great to have members contributing open source software

Agreed. Really cool project. I intend to play around with it some.
