ImageMagick – Sort wallpapers the easy way

If you happen to have a very large collection of wallpapers with mixed up resolutions then think no further. ImageMagick comes to your resuce to help you sort the wallpapers based on the resolutions.

According to the makers of ImageMagick :

ImageMagick^® is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to scale, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

I have put together a little shell script which will help you sort you wallpaper collection according to resolution.

#!/bin/bash
#
#Wallpaper Sorter v2
#This script is bought to you by 7sins@4geeksfromnet.com
#
#Use this to sort wallpapers according to resolutions
#
#This script when run in a folder full of wallpapers
#1. Determines the resolution of each wallapaper (can be either jpg, gif, png, bmp)
#2. Verifies if a folder with the same name as the resolution exists.
#	If the folders exists => Move the wallpaper into that folder
#	If the folder does not exists => Create the folder and then move the wallpaper into that folder
#3. Requires ImageMagick

LOCATION="$1"
echo "Moving into location $LOCATION"

cd "$LOCATION"

for file in *.jpg -o *.JPG -o *.gif -o *.GIF -o *.jpeg -o *.png -o *.bmp -o *.BMP
	do
		#Get  the image resolution
		resolution=$(identify -verbose "$file" | grep Geometry | awk '{ print $2}' | cut -f -1 -d\+)

		# Create a folder with the name of the resolution if it does not exist
		if ! test -d "${resolution}"
			then
				mkdir -p $resolution
				echo "Created folder $resolution"
		fi

		#Move the file into the folder, name of which is same as the resolution
		echo "Moving $file to folder $resolution"
		mv "$file" "$resolution"
	done

How to get the script up and running :

1. Copy the script code and make it executable

   :~$ chmod a+x sortPicsv2.sh
   

2. Execute the script using

   :~$ ./sortPicsv2.sh /home/username/path_to_wallpapers_folder
   

Replace the path /home/username/path_to_wallpapers_folder with the actual location of your wallpapers collection.

Happy sorting
