macOS Question on batch renaming

[zancine]

Hi there, I have quite many images files need to be named following a pattern, and the pattern goes like:

Section_1_1_NAME.jpg
Section_1_2_NAME.jpg
Section_1_3_NAME.jpg
Section_1_4_NAME.jpg
Section_1_5_NAME.jpg

Section_2_1_NAME.jpg
Section_2_2_NAME.jpg
Section_2_3_NAME.jpg
Section_2_4_NAME.jpg
Section_2_5_NAME.jpg

....and so on, where NAME keep being the same all the way.
The tricky part is for every 5 items, the first number increase by 1.
The original file names are in sequence, e.g. "file.001.jpg"

I am not a programmer but I guess this can be done with terminal to run commands and batch rename a whole folder of images?
I tried with automator but can't really figure out how to get that tricky part done.

It'd be a life saver if anyone can come up with a solution, as I have a lot of files need to be named that way.

Thanks!

There are lots of utilities that can do this for you. I've been using A Better Finder Rename for over 15 years and it's great: http://www.publicspace.net/ABetterFinderRename/

Copy this into terminal, press enter. DO NOT RUN ON YOUR ORIGINAL FILES, make a backup. This script renames everything, including any folder inside the target folder. So better create a new one and put your files inside it.

bash -c 'clear;echo "Please drag n drop the target folder into this window.";echo "Should look like this: /path/to/folder";echo -n "Input: ";read folder;cd $folder;if [ $? -ne 0 ];then echo "Wrong input, cant access directory, aborting";read;exit;fi;I=0;for filename in *;do let "A=(I/5)+1";let "B=I%5+1";newname="Section_$A""_$B""_$filename";echo "Renaming $filename to $newname";mv "$filename" "$newname";let "I++";done;echo "---All done!---";read'
