Poseidon is composed of two maven modules. The first is a "console" and the other a "terminal emulator" which uses the console.

• Cross Platform, I use both Linux and Windows so all the implemented internal commands will work accross OSs
• Eventually the project will implement most or all of Linux's bash internal commands http://linux.about.com/library/cmd/blcmdl1_builtin.htm
• Support for the ANSI colour output (see http://en.wikipedia.org/wiki/ANSI_escape_code or http://pueblo.sourceforge.net/doc/manual/ansi_color_codes.html)
• Support for plugins written specifically for Poseidon
• Support for executing any external command available on the user's path
• Built in SSH (Possibly using http://www.jcraft.com/jsch/ or https://github.com/shikhar/sshj (possibly http://mina.apache.org/sshd/ ?) pending investigation)

• Cross Platform
• Minimal (subset) of bash's internal commands
• Executing external command
• Plugins
• ANSI colouring support
• SSH

Features to implement in the order given

• Pending test, Poseidon Console could be replaced with http://jline.sourceforge.net/ since it implements most of what the console module does. That then leaves the focus on the Terminal and Implementing the internal commands

• CD

• export

• improve input from external process

• implement output to external process

• Implement plugin system

• Implement cross platform system access as a plugin using http://www.hyperic.com/products/sigar or any available alternative

Given what I've learn so far implementing this I think I'll set my sights on upgrading the aims Looking at http://www.gnu.org/software/bash/manual/ and Scala combinators, http://www.scala-lang.org/api/current/scala/util/parsing/combinator/Parsers.html I could effectively just port bash, by that I mean the commands and scripting. Depending on how easy/hard it is to use combinators. Which also gives me an excuse to continue learning Scala...
