Command line ELIZA chatbot

Is there an implementation of the classic ELIZA AI chat program that can be used on Ubuntu? I am looking for an ELIZA that can be used from the command line.

Solution 1:

Package search on Repology went us to libchatbot-eliza-perl Ubuntu package.

You can install it using commands below:

sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install libchatbot-eliza-perl

and then play with it

$ /usr/share/doc/libchatbot-eliza-perl/examples/simple

Welcome to your therapy session.

Liz:   I understand.
you:   They are meawing.
Liz:   Are you positive they are meawing?
you:   Yes
Liz:   Please go on.
you:   

It is Perl module, so you can read its source at /usr/share/perl5/Chatbot/Eliza.pm and man Chatbot::Eliza.3pm locally or online.
