Problem: minidlna use the title from the metadata, sometimes its better when the title = the filename. This script change the title from "'HERE THE NONE UNIQUE TITLE'" to the filename.

change_none_unique_minidlna_title.sh

for line in $(sqlite3 /root/minidlna/files.db "SELECT ID,PATH FROM DETAILS WHERE TITLE='HERE THE NONE UNIQUE TITLE';"); 
  do 
    id=$(echo $line | cut -d"|" -f1); 
    path=$(echo $line | cut -d"|" -f2); 
    echo $id; 
    echo $path; 
    sqlite3 /root/minidlna/files.db "UPDATE DETAILS SET TITLE='$(basename $path)' WHERE ID=$id;"; 
  done;
