http://twitter.com/janl brought me into attention about this interesting piece of code: http://www.davispj.com/2009/11/17/unix-in-python.html and this one: http://pwpwp.blogspot.com/2009/11/unix-in-14-lines-of-ruby-its-trivial.html which is implementing a barebones Unix like system in your favorite language
Here's my take on the game which is some pretty basic Haskell

> import System.IO
> main = 
>   putStrLn "You have no mail" >> loop
>   where 
>     loop = putStr "$ " >> hFlush stdout >> getLine >>= doCommand

#/bin/sh

# run inside a symfony project:
# ./extractinfo.sh log/frontend_dev.log 'execute(Query|Update|Insert)' | sort -n
# will return the number of queries per request

# in symfony 1.2+ you can try something like:
# ./extractinfo.sh log/frontend_dev.log 'sfPropelLogger'

# you can modify the second parameter to extract the required information and also point
