Downloading only new subtitles in RaspberyPi

I have problems with writing downloading subtitles on Raspberry Pi with bash script.

The issue is I would like to have 1 script running with cron every hour or so that would download subtitles for new video files in some directory.

There is a program called qnapi that automatically downloads subtitles in the correct format in the directory but it works for 1 folder and always re-downloads subtitle files.

usage is: 

qnapi /path/to/folder

So what I've found is 

find /media/pi/RaspStorage -iname "*.mkv"

basically gives me a list of all movie files. Now I would like to somehow compare if a *.srt subtitle file with a same base name exists and if no then somehow loop through all found files with qnapi command. Write it in a bash script and cron it.

Solution

  • thanks for help :)

    I got it working

    #!/bin/bash
echo "Updated DLNA folder"

sudo minidlnad -R

for file in $(find /media/pi/RaspStorage -name '*.mkv' -or -name '*.avi'); do
 name=${file:: -4}
 ext=".srt"
 name=$name$ext

 if [ -f $name ]; then
  echo "Napisy już ściągnięte dla:" "$(basename "$file")"
 else
 qnapi "$(dirname "$file")"/"$(basename "$file")"
 fi
done

    Works fine. All subtitles are downloading and if there are some already it's skipping
