Do you do any bash scripting? How are you at a command line? Pretty comfortable? Are you at all familiar with ImageMagick?

What are you basing "duplicates" on? Name? Size? Size in pixels? Size in bytes? Date? Any/all of these can be ambiguous.

Which is why I'll *NEVER* be a full-blown GUI user!

I can do in seconds or minutes at a CLI what takes hours or days in a GUI.

How about adding their dimensions to their names instead? In other words, instead of having:

Code:

fantasy1 (a directory)

. fantasy1_3000x3000 (subdirectory)
.. picture1.jpeg
.. picture2.jpeg
.. picture3.jpeg

. fantasy1_3500x3500 (subdirectory)
.. picture1.jpeg
.. picture2.jpeg
.. picture3.jpeg

. fantasy1_4000x4000 (subdirectory)
.. picture1.jpeg
.. picture2.jpeg
.. picture3.jpeg


fantasy2 (a directory)

. fantasy2_3000x3000 (subdirectory)
.. picture1.jpeg
.. picture2.jpeg
.. picture3.jpeg

. fantasy2_3500x3500 (subdirectory)
.. picture1.jpeg
.. picture2.jpeg
.. picture3.jpeg

. fantasy2_4000x4000 (subdirectory)
.. picture1.jpeg
.. picture2.jpeg
.. picture3.jpeg

you could have:

Code:

. fantasy1 (a directory)
.. picture1_3000x3000.jpeg
.. picture2_3000x3000.jpeg
.. picture3_3000x3000.jpeg
.. picture1_3500x3500.jpeg
.. picture2_3500x3500.jpeg
.. picture3_3500x3500.jpeg
.. picture1_4000x4000.jpeg
.. picture2_4000x4000.jpeg
.. picture3_4000x4000.jpeg

. fantasy2 (a directory)
.. picture1_3000x3000.jpeg
.. picture2_3000x3000.jpeg
.. picture3_3000x3000.jpeg
.. picture1_3500x3500.jpeg
.. picture2_3500x3500.jpeg
.. picture3_3500x3500.jpeg
.. picture1_4000x4000.jpeg
.. picture2_4000x4000.jpeg
.. picture3_4000x4000.jpeg

The files could be renamed however you like, for example, 3000x3000_picture1.jpeg or picture1_3000.jpeg, etc.

Combining bash commands with ImageMagick commands, all of the above could be accomplished quickly. IM has a zillion options, literally infinite when you're combining them, and there's definitely a learning curve, especially if you're not already pretty comfortable at a command line with basic *nix usage.

Using IM's identify command, here's an example of it determining an image's attributes--only the attributes I told it to identify, its width and height:

Code:

$ identify -format "%wx%h" pg7.png
638x877

Taking that output and using a little bash and a little IM, you could rename the files so they include the dimensions in their names.

Like I said, there's definitely a learning curve, but I can't stress strongly enough how useful IM is once you're used to it. I'd be lost without its power and versatility. I can literally process hundreds of image files, in any number of ways, in a VERY small fraction of the time it would take to do it manually. Take a look at ImageMagick, including some of its options to see how powerful it is.

awesome but i cheated some and had a friend help me with a bash script that uses exiftool

#!/bin/bash
#
#-----------------------------------------------
# organized pictures by resolution
# 9to5 - AndroidForums.com
#-----------------------------------------------
#
# Note, this script uses exiftool to find the picutre width/height
# and it will only work with one file type at a time (so far)... 
# if you want to change the file type (to say, png) then change the 
# *.jpg to *.png in line 17

# set dir to your picture directory
dir=./
typ=$1

# file type change here 
for line in $(ls *.$typ)
do
	psize=$(exiftool $line | grep "Image Size" | cut -d ":" -f 2 | cut -d " " -f 2)
	# That will give use the resolution of the file...  example : 900x600 as variable psize		
	ls $psize 1>/dev/null
	ls_check=$?
	if [[ $ls_check -eq 0 ]]
	then
		mv $line $psize 1>/dev/null
	else
		mkdir $psize
		mv $line $psize 1>/dev/null
	fi	
	
done

#unset variables
unset {line,psize,ls_check}

it has a few flaws but does work maybe we can come up with something. At moment filenames with spaces are a no no so i'll have to rename those that have spaces in them. Also as you can see can only do one type at a time still much faster than the manual way i did the first one.

on the fedora site my signature is Command Line Flunkie Gui Junkie

I wish to change this
