Yes. I imagined you only had two copies.

Good idea if there are multiple copies of some images.

Leave out the 'd' flag on uniq. And if all your files are jpgs, add
a filter to md5sum or it'll try and process the 'duplicates' directory
we created earlier.

awk {'print $1'} is the same as cut -f 1 d ' ', but I think cut's faster
(it should be lighter than awk)

mkdir unique
md5sum *.jpg | sort | awk {'print $2 " " $1'}  | uniq -f 1 | \
cut -f1 -d ' '

Then wrap that in the for command, because:

Yes, cos you're trying to run:
mv duplicates file1 file2 file3

whilst mv is 'mv file1 file2 file3 <destination>', so you're the wrong
way round. You may be able to persuade xargs to do something different,
but I don't know it that well.

We're well offtopic for ImageMagick now, so I suggest that you reply
just to me from now on. (any IM readers wanting to know how the exiting
tale concludes, email me...)
