Universal app/console for Symfony applications

sf.php

#!/bin/bash

# This script allows you to run `sf` instead of app/console and you don't have
# to be the root of a Symfony application. It will traverse the parent
# directories until it finds app/console.

targetfile=app/console
path=.

# Get the canonical directory of the current "path"
while [[ "`readlink -f $path`" != "/" ]];

    if [ -f $path/$targetfile ]; then
        # If we found it, run it
        echo `readlink -f $path`/$targetfile
        cd $path
        php app/console $*

        # Return the same status code as what app/console returned with
        exit $?

    # Move up a directory
    path=${path}/..
