move files into folders and rename existing files.

Hello everyone.

A few years ago i got some help here with moving and sorting files with great success.

I have modified the script a bit for a new situation and now i'm stuck.

The script moves files into specific folders depending on the filename and if there are any existing files rename them but i cant get the rename to work. I tried with with the --backup command:

mv -v -b \"$f1\" \"$jpg\" 

But all i get is illegal option, is there any other way to append existing files?

Also i'm sure there must be a better way to loop through the files instead of using two "while do" after each other, though it seems to work just fine.

Example filenames and folder structure:

15512-1.tif
15512-1.jpg

180313-1.tif
180313-1.jpg

2002005-1.tif
2002005-1.jpg

OBJECTS/2018/1803/180313/JPEG/180313-1.jpg
OBJECTS/2018/1803/180313/JPEG/180313-2.jpg
OBJECTS/2018/1803/180313/JPEG/old1_180313-1.jpg (exampl of renamed existing file)
OBJECTS/2018/1803/180313/JPEG/old2_180313-1.jpg
