Bash Script to archive files into folders based on part of filenames

I have found examples of similar questions sorting files into folders based on the filename but don't really know where to start with this as i need to loop through multiple things and could do with some help please.

I have a folder of telephone recordings with the following file name format:

OUT260-20140828-125114-1409226674.42655.wav

it is split up into several parts

OUT260 = 260 is the name of the extension
20140828 = the date
125114 = the time

the rest im not sure I think it's some king of id because it increments each time.

what i want to end up with is the following folder stucture created by a cron job / bash script

top level

extension numbers eg

260, 261 ,262

then year then month then day then multiple files eg for the file name above 260-1251.wav

so if this can be achieved the example file would end up as below

/Recordings/260/2014/08/28/260-1251.wav

i have the following example which is a more basic example:

#!/bin/bash

for full_filename in *jpg; do
extension="${full_filename##*.}"
filename="${full_filename%.*}"
mkdir -p "$filename/picture"
mv "$full_filename" "$filename/picture"
done

Hope that makes sense any help much appreciated

A quick and dirty way to do this is using sed to replace the name by the path:

#!/bin/bash
for f in OUT*.jpg
do
    res=$(echo "$f" | sed -r 's#^OUT([0-9]+)\-([0-9]{4})([0-9]{2})([0-9]{2})\-([0-9]{4}).*\.(.*)$#/Recordings/\1/\2/\3/\4/\1-\5.\6#g')
    mkdir -p `dirname "$res"`
    mv "$f" "$res"
done

For example if $f is OUT260-20140828-125114-1409226674.42655.wav, $res is /Recordings/260/2014/08/28/260-1251.wav. For filenames that don't follow the correct pattern, $res is the same as $f so nothing happens.

sed makes use of regular expression to find and replace (parts of) the filename. The syntax is somehow hard to explain but there are a lot of good tutorials on the internet.

Furthermore please note that it is in general not a good idea to use a root dir like `/Recordings``...

Please use cp first for testing...
