Renaming and moving files and folders with bash script

Question

I'm trying to make a bash script that goes to every single folder and then renames all the files in the folders numerically. There are multiple folders and multiple files within the folders. I want to rename all of them and then transfer all of the files to a single folder. The code I have so far is

#! /bin/bash
FOLDERS=$(ls *)
COUNT=0
for folder in $FOLDERS
    do
        cd $folder
        FILE=$(ls *)
            for file in $FILE
                do
                    echo "working on it"
                    COUNT=$((COUNT+1))
                    mv $file $COUNT
        cd ..
done

but it isn't working...

Any thoughts on how to do this?

Answer 1

Something like this will do the job:

#!/bin/bash
shopt -s globstar
source='/your/source/folder'
target='/your/target/folder'
i=0
for f in ${source}/**; do
    if [[ -f "${f}" ]]; then
       ((i++))
       mv "${f}" "${target}/${i}"
    fi
done

Answer 2

You can do this in Ruby and hence, you don't have to worry about special characters in filenames :

#!/usr/bin/ruby

require 'find'
require 'fileutils'


source_dir="./"
target_dir="target/"
count = 0

Find.find(source_dir) do |path|
  next if path =~ /(.*\.rb$|.*\.\/$|.*\.\.\/$)/
  puts "Found : " + path
  File.rename(path,count.to_s) 
  FileUtils.mv(source_dir + count.to_s, target_dir)  
  count = count + 1
end
