Organize your photos with a script

I have a lot of photographs and they where distributed over several external disks and computers, so I needed a way to organize them, I've searched the web and found a script that used the exif data to organize the images into folders by year, month, day. So I've picked that up and modified a bit to better fit my neads, I ended up with the script that you can check after the break.
I also use this script to move the photos from my camera to my PC.

Note: I don't remember the link from where I got the original script but I will update this post as soon as I find it. The original script can be found here: http://davehope.co.uk/Blog/sorting-your-photos-with-bash/


This script organizes the following file types:

• jpg/jpeg
• nef
• png
• bmp
• avi
• mov
• mpg
• mp4

It recursively moves the files from the source dir (first argument) into a structure of folders on the destiny dir (second argument), it looks for duplicated files and in case of finding two different files with the same name it keeps the bigger file.

In the end it cleans the source directory by removing the folders that where left empty.

And here you have the script:

#!/bin/bash
# Script to sort Photos and movies from digital cameras into folders by date
# When possible it uses the exif information on the photo to get the original date
# otherwise it uses the last modification date
cfgSource="$1"
cfgDestRoot="$2"
toUpper() {
    echo $1 | tr  "[:lower:]" "[:upper:]"
}
toLower() {
    echo $1 | tr "[:upper:]" "[:lower:]"
}
escapeSpaces(){
    echo $1 | sed 's/ /\\ /g'
}
if [ "$#" != "2" ]; then
    echo "Usage: $0 <source> <destination>"
    exit 1
fi
which stat > /dev/null
# make sure stat command is installed
if [ $? -eq 1 ]
then
    echo "stat command not found!"
    exit 2
fi
which identify > /dev/null
# make sure identify command is installed
if [ $? -eq 1 ]
then
    echo "identify command not found!"
    exit 3
fi
