remove duplicated roms : Please read this simple script

[kok00]

roms path.
/home/pi/RetroPie/roms/mame-mame4all

how do i put a simple script in this folder and run it off command line just execute it and let it run through it using compare method or if statements anything that does the job without slowing it down.

or

compare two folders
/home/pi/RetroPie/roms/mame-mame4all
/home/pi/RetroPie/roms/mame-libretro
compare two folders and remove duplicated .zip

may anybody share a simple script so that i can learn from it.

is retro-pie running of bash script Linux command.

found this in a site

#!/bin/bash
declare -A arr
shopt -s globstar

for file in **; do
  [[ -f "$file" ]] || continue

  read cksm _ < <(md5sum "$file")
  if ((arr[$cksm]++)); then 
    echo "rm $file"
  fi
done

files=(*)
count=${#files[@]}
for (( i=0 ; i < count ;i++ )); do 
    for (( j=i+1 ; j < count ; j++ )); do
        if diff -q "${files[i]}" "${files[j]}"  >/dev/null ; then
            echo "${files[i]} and ${files[j]} are the same"
        fi
    done
done

how do i modify that so it checks both folders and the same name.zip and remove

are these retropie batch script codes that will work.

        if [ -z "$compare" ]; then
            echo the "$target_file" is a copy "$candidate_file"
