mperlet / change_none_unique_minidlna_title.sh
Created August 18, 2015 13:38
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.
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;
