Symfony config file compare script

When working on a Symfony project, someone else will make a change to a config file or add new functionality that also need to be configured on my local machine for the project to work.

As I got tired of having to manually figure out what was going on I wrote a shell script to do that for me.

This script will gather all .dev files for a given directory, check whether there is an accompanying file without the .dev extension and output the diff between both.

#!/usr/bin/env bash
# ==============================================================================
#
# ------------------------------------------------------------------------------
# This script will try to build check whether there have been new or changed .yml
# files in a directory. It achieves this by searching for '.dev' files, looking
# if there is a mirror file "sans" .dev extension and outputting the diff
# between both.
#
# It takes one parameter, the path to the folder to check files in.
# ------------------------------------------------------------------------------
# The following ExitCodes are used:
#
# 64 : General Error
#
# 65 : Not enough params given
# 66 : The given path is not a directory
#
# ==============================================================================
# ==============================================================================
# CONFIG VARS
# ------------------------------------------------------------------------------
set -o nounset # exit on use of an uninitialised variable, same as "set -u"
set -o errexit # exit on all and any errors, same as -e
declare g_sFolderPath
# ==============================================================================
# ==============================================================================
# APPLICATION VARS
# ------------------------------------------------------------------------------
declare -i g_iExitCode=0
declare -i g_iErrorCount=0
declare -a g_aErrorMessages
readonly T_BOLD=`tput bold`
readonly T_NORMAL=`tput sgr0`
