I want to copy latest file based on filename in (filename_config) & in each directory based on config file (dir_config) to backup directory.

In one directory could have > 1 filename to be copy.

dir_config:

/XXX/DIR1

/XXX/DIR2

/XXX/DIRB

/XXX/DIRY7

filename_config:

ABCD

123AB

E142

However my bash script it only copy 1 filename to the backup directory even though in the dir_config having multiple filename to be copy.

Example Output:

[Wed Jul 10 13:55:09 UTC 2024] Copy latest file from /srv/XXX/DIR1/12-ABCD_1.0_20231103082747609.zip to /srv/backup_data/XXX/DIR1

[Wed Jul 10 13:55:09 UTC 2024] Copy latest file from /srv/XXX/DIR2/E142_1.0_20231103082747609.tar to /srv/backup_data/XXX/DIR2

[Wed Jul 10 13:55:09 UTC 2024] Copy latest file from /srv/XXX/DIRB/17-ABCD_1.0_20231103082747609.tar to /srv/backup_data/XXX/DIRB

[Wed Jul 10 13:55:09 UTC 2024] Copy latest file from /srv/XXX/DIRY7/XY-123AB_1.0_20231103082747609.csv to /srv/backup_data/XXX/DIRY7

This my script:

for i in $(<$dir_config)

do
    
    cd $Source_Dir
    
    for y in $(<$filename_config)
    do
    
    latest_file=$(LC_ALL=C ls $i *$y* -cr  | tail -1)

    done
    
    cp "$Source_Dir$i/$latest_file" $Backup_Dir$i
    WriteLog "Copy latest file from $Source_Dir$i/$latest_file to $Backup_Dir$i "
    
done

I’m expecting as below:

Output:
