Find all files in a directory, flatten, and rename to UUID

script.sh

#!/usr/bin/env bash

# This script will find all files in the current directory and rename them using UUID and flatten the directory structure.

# This script is useful when you have a directory structure like this:
#   src/dir1/dir2/dir3/file1.txt
#   src/dir1/dir2/dir4/file2.txt
#   src/dir1/dir2/file3.txt
#
# And you want to flatten it to this:
#   dest/6f4f6995-0d76-4b53-829a-dfa480b2591f.txt
#   dest/a453bc30-4631-447d-8f60-d36bb8b372cc.txt
#   dest/9ba5fbd9-6a59-4253-b948-dc9116dab727.txt


# Get the source directory from first argument
current_dir=$1
# Get the destination directory from second argument
destination_dir=$2

# Find all files in the current directory

find $current_dir -type f | while read file; do
    # Get the filename without the path
    filename=$(basename "$file")
    # Get the extension of the file
    extension="${filename##*.}"
    # Get the filename without the extension
    filename="${filename%.*}"
    # Generate a UUID
    uuid=$(uuidgen | tr "[:upper:]" "[:lower:]")
    # Rename the file to UUID.extension
    echo "$file" "$destination_dir/$uuid.$extension"
    mv "$file" "$destination_dir/$uuid.$extension"
done
