重命名 mp3 文件的 Bash 脚本或函数

Question

想要批量重命名mp3文件到以下方案

my-artist_my-title.mp3

理想情况下，我更喜欢有一个

bash script

，我会用它来触发：

$ rename-mp3 directory-with-subdirectories-with-mp3-files

搜索类似的解决方案，我发现了this功能。我修改了它并且它有效，部分！标有

#?

的正则表达式修改不起作用。

  function rename-mp3() {       # input is an mp3 file: i.e. find -name 's3  24)3ü6   Dț67  .mp3' -exec bash -c 'rename-mp3 "$@"' bash {} \;
                                # extract metadata from file
  artist=`ffprobe -loglevel error -show_entries format_tags=artist -of default=noprint_wrappers=1:nokey=1 "$1"`
  title=`ffprobe -loglevel error -show_entries format_tags=title -of default=noprint_wrappers=1:nokey=1 "$1"`
  artist="${artist/\&/}"        #? delete all non-numeral, non-latin, and non-space characters (&, %, !, ', ä, ö, ü, ă, ț, etc.)
  title="${title/\&/}"          #? delete all non-numeral, non-latin, and non-space characters (&, %, !, ', ä, ö, ü, ă, ț, etc.)
  artist="${artist// +/\-}"     #? replace all spaces with "-", if more then one in sequence substitute only one "-"
  title="${artist// +/\-}"      #? replace all spaces with "-", if more then one in sequence substitute only one "-"
  filename="$artist_$title.mp3" # paste artist and title together
  filename="${name,,}"          # lowercase everything
  echo "$filename"              # display new filename
  cp "$1" "renamed/$name"       # copy renamed file to the renamed folder
}
