Organize photos and other files on an year/month/day folders structures (See related posts)

This script can organize you media colelction in folders by year/month/day.
For jpeg files, looks in exif for the creation date, if that file has that kind of metadadata. For any other files it only checks the creation time.
The script takes 3 option on the command line. A command which may be -m, -c or -f, a source folder and a destination folder.
Using -c will copy the files from souce to destination, -m will move them, - f will also move them, by making first a copy then a delete. -f option may used when -m doesn't work, the most common situation beeing when you want to move the files from one file system to another(e.g. from your ext3 local hard drive to an external fat32 usb harddrive)
After you organize the files, you can find duplicate items using my previous snippet.
This script have been inspired from here
