Create a new subfolder with randomly shuffled symlinks of the files in current folder for further non-destructive processing.

SHUFDIR=shuffled && mkdir $SHUFDIR && for file in ./*; do ln -s "$PWD/$file" "$PWD/$SHUFDIR/$(od -A n -N 8 -t x8 /dev/urandom | tr -dc '[:print:]')-${file##*/}" ; done
Ideal for shuffling e.g. photo's with Imagemagick's montage, for instance in combination with: montage -density 300 -resize 512x384 -mode concatenate -tile 7x7 shuffled/* shuffled/output.pdf you can generate a PDF montage of 7x7 random photo's per page with properly scaled images. If there are other files than photo's in your folder, replace pattern './*' with for instance './*.jpeg' to select the file type you want.
