This is a quick bash script I wrote to walk through directories and delete duplicate photos based on MD5.
It was written for a specific scenario and I highly advise against using it as-is. Instead, read through it and tweak it to your own situation. I would appreciate any feedback.
HF="$PWD/hashes.out"
echo HF=$HF
rm "$HF"
touch "$HF"
for x in `ls -bd *`; do
echo x=$x
cd $x
for y in *; do
m=`md5sum "$y" | awk -F '{print $1}'`
echo $y: $m
g=`grep $m "$HF"`
echo g=$g
if [[ "$g" != "" ]]; then
echo "MATCH!!";
echo rm "$y"
else
echo "no match"
echo $m >> "$HF"
fi
done
cd ..
done
