To Find Duplicate files using latest in Linux

I have tried the following code and with that i couldnt achieve what i want.

Code:
    #!/usr/bin/bash
    find ./ -type f \( -iname "*.xml" \) | sort -n > fileList
    sed -i '/\.\/fileList/d' fileList
    NAMEOFTHISFILE=$(echo $0|sed -e 's/[]\/()$*.^|[]/\\&/g')
    sed -i "/$NAMEOFTHISFILE/d" fileList
    cp fileList auxFileList
    while read FILENAME
    do
        sed -i '1d' auxFileList
        #echo "Comparing $FILENAME with :"
        #Read the aux file and compare current file with every other element in the file
        while read COMPFILENAME
        do
            RETURN=$(diff $FILENAME $COMPFILENAME)
            if [ "$RETURN" == "" ]
            then
            cat $FILENAME | awk ' BEGIN { FS="_" } { printf( "%03d\n",$2) }' | sort | awk ' { printf( "data_%d_box\n", $1)  }'
             #echo "$FILENAME AND $COMPFILENAME are identical"
             #rm -r $FILENAME
            fi
            #echo "  $COMPFILENAME"
        done<auxFileList
    done<fileList
    rm fileList auxFileList &>/dev/null
    printf '\n\n'

this code selecting all the files initially. I have to amend my code in such a way that only recent modified filename patterns for example
Code:
    File 1: AAA_555_0000 
    File 2: AAAA_123_123 
    File 3: AAAA_452_452 [latest]
    
    File 4: BBB_555_0000 
    File 5: BBB_555_555 
    File 6: BBB_999_999 [latest]
    
    File 7: CCC_555_0000 
    File 8: CCC_000_000 
    File 9: CCC_000_111 [latest]

Script has to pick latest file in all the filename patterns in the folder and it should compare and delete the duplicates.

Appreciate if you can help me with this logic.

Thanks much!

SERVICE(8)						    BSD System Manager's Manual 						SERVICE(8)

NAME
service -- control (start/stop/etc.) or list system services SYNOPSIS
service -e service -R service [-v] -l | -r service [-v] <rc.d script> start|stop|etc. DESCRIPTION
The service command is an easy interface to the rc.d system. Its primary purpose is to start and stop services provided by the rc.d scripts. When used for this purpose it will set the same restricted environment that is in use at boot time (see below). It can also be used to list the scripts using various criteria. The options are as follows: -e List services that are enabled. The list of scripts to check is compiled using rcorder(8) the same way that it is done in rc(8), then that list of scripts is checked for an "rcvar" assignment. If present the script is checked to see if it is enabled. -R Restart all enabled local services. -l List all files in /etc/rc.d and the local startup directories. As described in rc.conf(5) this is usually /usr/local/etc/rc.d. All files will be listed whether they are an actual rc.d script or not. -r Generate the rcorder(8) as in -e above, but list all of the files, not just what is enabled. -v Be slightly more verbose ENVIRONMENT
When used to run rc.d scripts the service command sets HOME to / and PATH to /sbin:/bin:/usr/sbin:/usr/bin which is how they are set in /etc/rc at boot time. EXIT STATUS
The service utility exits 0 on success, and >0 if an error occurs. EXAMPLES
The following are examples of typical usage of the service command: service named status service -rv The following programmable completion entry can be use in bash(1) for the names of the rc.d scripts: _service () { local cur cur=${COMP_WORDS[COMP_CWORD]} COMPREPLY=( $( compgen -W '$( service -l )' -- $cur ) ) return 0 } complete -F _service service SEE ALSO
bash(1) (ports/shells/bash), rc.conf(5), rc(8), rcorder(8) HISTORY
The service utility first appeared in FreeBSD 7.3. AUTHORS
