Rename Duplicate file name to another name in multiple folders [closed]

You don’t show much effort to let us help you solving this. But since I’m learning bash scripting, I took your question as practicing.

So… here is a bash script to rename duplicated files.

/!\ The renamed files will be in the folder of first argument. So, in your case, you’ll have to launch it like this :

  • Rename duplicated files from folder1 and folder2 :

    $ mv_duplicates_script.sh /path/to/FOLDER1 /path/to/FOLDER2

  • Rename duplicated files from folder1 and folder3 :

    $ mv_duplicates_script.sh /path/to/FOLDER1 /path/to/FOLDER3

  • Rename duplicated files from folder3 and folder2 :

    $ mv_duplicates_script.sh /path/to/FOLDER3 /path/to/FOLDER2

Note that you have to set FOLDER2 at last argument for the renamed files go to FOLDER3.

#!/bin/bash

# if missing args, print Usage
##############################
if [[ -z $1 ]] || [[ -z $2 ]]
  then
    echo "Usage : `basename $0` /absolute/path/to/folder1 /absolute/path/to/folder2"

    # exit with failed status
    exit 1
fi

# test if folders exist
#######################
if [[ ! -d $1 ]]
  then
    echo "ERROR : Folder $1 not found..."

    exit 1
fi

if [[ ! -d $2 ]]
  then
    echo "ERROR : Folder $2 not found..."

    exit 1
fi

# get filenames from folder 1
#############################

cd $1

i=0
for f in *.txt
  do
    folder1_files[$i]=$f
    ((i++))
done



# get filenames from folder 2
#############################

cd $2

i=0
for f in *.txt
  do
    folder2_files[$i]=$f
    ((i++))
done


# compare and move duplicates
#############################

for f in ${folder1_files[@]}
  do
    for g in ${folder2_files[@]}
      do
        if [[ $f == $g ]]
          then
            echo "Duplicate file : $g"
            echo "Renaiming to DUPLICATE_$g in $1"
            mv $1/$g $1/DUPLICATE_$g
        fi
    done
done

exit 0

Use it as :

$ mv_duplicates_script.sh /absolute/path/to/folder1 /absolute/path/to/folder2

Hope it helps.
