This script lets you sort your photos based on the Date in EXIF information.
Its handy because I can easily sort my photos on date, and re-sort others that have been already sorted incorrectly.
It moves files into a date directory, where the date is specified by the EXIF information.
Usage: ./mv_by_exif.sh *.jpg foobar.jpg foo/bar*.jpg
An example date directory that is created: 2007-04-03
