Run a Shell-Script with script progress as Notification

Hi,

i used a script with LibreELEC 9 that checks for new files in a "sync-folder" on the Flash drive on my Network router and moves the files to the Hard drive on the HTPC. The scripted runs in background and there was so notification while its running or after completing the process.

Is there a way to show a Notification while the script is running? something like "copying file 1 of 3 - <name-of-the-file>? similar to the notification i have when i update the database?
