#! /bin/bash
# Script:    FindJpgOlderThanTif.sh
# Purpose:   This is part of a RAW workflow, where RAW -> TIF -> JPG
#            If a JPEG file is found that is older than the corresponding TIF, 
#            then something is fishy.
#            This script offers various actions when a file is found
#            (default is to open explorer on the inaccurate file).
#            It assumes you save your RAW, TIF and JPEG in the same location.

# You need cygwin to run this on Windows: http://www.cygwin.com/
# To launch this from Explorer, create a FindJpgOlderThanTif.bat file with the following:
#	SET PATH="/usr/local/bin:/usr/bin:/bin"
#	c:\cygwin\bin\bash FindJpgOlderThanTif.sh
#	PAUSE
