Another Windows playlists importer

Help and Support
3

I’ve finally been able to convert the playlists getting full metadata, included albumart.
This version makes two conversions: first converts Windows playlists to simple, temporary Volumio ones. REST commands are used to do everything from CLI. Entries only have the uri of the files. This ones are played with a curl shell command for short time. Second, the queue with the current playlist is converted to complete Volumio one.
Assumptions are the same as above versions except for point 6. A backup of converted lists is also made in the script folder. Lists can’t have spaces in their names unless one converts spaces to some other character and later does the opposite

#!/bin/bash

# Set your Windows PC music folder path
win_path='E:\\Data\\Music\\'

# Set your Volumio music folder path
vol_path='USB\/disk_label\/Data\/Music\/'

# Remove BOM
find . -type f \( -name "*.m3u8" \) -exec sed -i '1s/^\xEF\xBB\xBF//' {} +

# Convert Windows CRLF To Unix LF line endings
sed -i 's/\r$//' *.m3u8

# Replace Windows music folder with Volumio music folder path
sed -i "s%$win_path%$vol_path%g" *.m3u8

# Replace remaining \ with /
sed -i 's/\\/\//g' *.m3u8

# Remove first line (containing #)
sed -i '1d' *.m3u8

# Prepend {"service":"mpd","uri":" to each line
sed -i 's/^/{"service":"mpd","uri":"/' *.m3u8

# Append "}, to each line
sed -i 's/$/"},/' *.m3u8

# Append "]" to last line of file
sed -i '$s/$/]/' *.m3u8

# Replace },] with },] in last line of file
sed -i 's/},]/}]/' *.m3u8
