Simple script to go through all the files in a folder and move any that are identical to a "duplicates" folder. Identical is defined as having the same md5 hash. I used this to save space in a folder that had multiple copies of the same video clips I shot on my iPhone.
# Make a directory to hold any duplicates we find; this may result in "directory already exists" if running a second time.
mkdir duplicates
# Create an empty log file to hold hashes so we know which files we have seen before
log=/tmp/md5copylog-`date +%s`.log
touch $log
# For any file (can change this to *.MOV to do just .MOV files, for example)
for f in *.*;
do

Copy files with md5 duplicate check

echo "Attempting to copy files to $1"

echo "No target destination specified"
