How to sort files into directories and subdirectories by name

I am new in the world of Linux and I need some advice.

I am continuously saving files in one folder in the following format:

20221021-164822-778711241-604184411.mp3
20221021-164911-778711241-607925196.mp3
20221021-165005-778711241-775371830.mp3
20221021-165152-778711241-777604545.mp3
20221021-165328-778711241-739031020.mp3
20221021-165410-778711241-723150081.mp3
20221021-165517-778711241-604144169.mp3
20221021-165612-778711241-737180820.mp3
20221021-165702-778711241-604292686.mp3
20221021-165748-778711241-777603529.mp3

the format is

YYYYMMDD-somenumbers.mp3

I would need cron to put these files into these tree folders every day

/path/YYYY/MM/DD

Do you have any advice, please?

Thank you very much in advance.

This works here:

#!/usr/bin/env bash

# "for" loop to iterate over all *mp3* files
for i in *.mp3; do
    # Use substring to get the name of the directory for each file    
    dr="${i:0:4}/${i:3:2}/${i:6:2}"
    # find out if the directory exists; if it doesn't, create it
    [ -d "$dr" ] || mkdir -p "$dr"
    # Move the file
    mv "$i" "$dr"
done

If you have a lot of files to move every day, you might save yourself a few CPU cycles by creating the entire directory structure in advance:

# Does not allow for leap years
for i in {1..365}; do mkdir -p $(date +'%Y/%m/%d' -d "2021-12-31 +$i days"); done

You could then remove this line:

    [ -d "$dr" ] || mkdir -p "$dr"

You may end up with a lot of empty directories, but they don't take up much space.

I finally wrote this script and it seems to work:

mkdir /destination-folder/$(date +"%Y")
mkdir /destination-folder/$(date +"%Y")/$(date +"%m")
mkdir /destination-folder/$(date +"%Y")/$(date +"%m")/$(date +"%d")
mv /source-folder/* /destination-folder/$(date +"%Y")/$(date +"%m")/$(date +"%d")

and cron will always run it at 23:50
