How to do it...

1. Open a terminal, and create the file-deduplicator.sh script.

The following is a code snippet of the script:

#!/bin/bashdeclare -a FILE_ARRAY=()function add_file() {  # echo $2 $1  local NUM_OR_ELEMENTS=${#FILE_ARRAY[@]}  FILE_ARRAY[$NUM_OR_ELEMENTS+1]=$1}function del_file() {  rm "$1" 2>/dev/null}

2. Run the setup command if not already: run $ bash dsetmkr.sh and then run $ bash ./file-deduplicator.sh. Enter files_galore/ at the prompt and press Enter:

$ bash dsetmkr.sh $ bash file-deduplicator.shEnter directory name to being searching and deduplicating:Press [ENTER] when readyfiles_galore/#1 f559f33eee087ea5ac75b2639332e97512f305fc646cf422675927d4147500d4c4aa573bd3585bb866799d08c373c0427ece87b60a5c42dbee9c011640e04d75#2 f7559990a03f2479bf49c85cb215daf60417cb59875b875a8a517c069716eb9417dfdb907e50c0fd5bd47127105b7df9e68a0c45a907dc5254ce6bc64d7ec82a ...
