Create Folder from File name Remove Spaces with Variables

#!/bin/bash
#noParity=true
#arrayStarted=true

## This script will create folders from files. First it will remove
## all spaces and create a folder from the file name
## It will also move files/directories to final location if you uncomment down in the code
## It will also change your file permissions from root to nobody uncomment below to use
## Adjust your directories below for your needs.
## Have Questions ask kizer on unraid forum
## All code has been cobbled together by me and tested on my own system to insure it works

## Source Directory of Files, change below to your path. I left mine in for example
FROM=/mnt/cache/uploads/Tv-Incoming

## Script will leave renamed files where they are unless you comment and adjust below
## Keep in mind you have to uncomment below and the 2nd to last line to work

## Only if you want to move new folder to another location. Change below to your path
## and uncomment near the very bottom of this script
NEWLOCATION=/mnt/cache/Media/Movies

## Remove Spaces-Linux and spaces are no good together
cd $FROM/
for f in *\ *; do mv "$f" "${f// /.}"; done

## Create Folder from name and move to final location. File types editable below.
## If File type is not listed below it will not be moved or renamed
for FILE in `ls $FROM/ | egrep "mkv|mp4|avi|vob|iso|MKV|MP4|AVI|VOB|ISO"`
do
DIR=`echo $FILE | rev | cut -f 2- -d '.' | rev`

## Make Directory
mkdir $FROM/$DIR

## Move File into new Directory
mv $FROM/$FILE $FROM/$DIR
