@Error404, Please try below solution.

cd to the directory where you have the files and execute below command. You may redirect the output to a temporary file.


Code:
ls -l|sort -k9 | awk '{OFS="."}{print $5,$9}' | awk -F"." 'BEGIN{row=$0;T=$2;} {if ($2==T) {if($1>max){max=$1;row=$0;}} else {print row;row=$0;max=0}; T=$2} END{print row}'

The command first lists all the files under the directory and picks the filename ($9) and size ($5). You may adjust this if you are getting the filename and size in different positions.

The fiesize is output as first field and the filename follows. I have used "." as an output delimiter to easily fetch the file with maximum size.

I created below files in a directory called tempdir:
Code:
LAJ.g.gif-1.JPEG                    4
LAJ.g.gif-2.JPEG                   12
LKJFDA01.gf.gif-1.JPEG           0
LKJFDA01.gf.gif-2.JPEG           0
LKJFDA01.gif-3.JPEG               4
OLUSDN.gf.gif-1.JPEG             0


The output was as below.
Code:
12.LAJ.g.gif-2.JPEG
4.LKJFDA01.gif-3.JPEG
0.OLUSDN.gf.gif-1.JPEG

The first field in the output is the maximum size of the file starting with 2nd field (i.e., LAJ, etc) in bytes.
