根據文件名創建目錄樹

我有大量具有以下結構的文件：

[Lion] 2015 Africa Book.pdf
[Lion] 2015 Africa Magazine.pdf
[Lion] 2016 Africa Book.pdf
[Lion] 2016 Africa Magazine.pdf
[Lion] 2015 Asia Book.pdf
[Lion] 2015 Asia Magazine.pdf
[Lion] 2016 Asia Book.pdf
[Lion] 2016 Asia Magazine.pdf
[Tiger] 2016 Africa Book.pdf
[Tiger] 2016 Africa Magazine.pdf
[Tiger] 2015 Asia Book.pdf
[Tiger] 2015 Asia Magazine.pdf
[Tiger] 2016 Asia Book.pdf
[Tiger] 2016 Asia Magazine.pdf

等等

基本上文件遵循以下模式：[{animal}] {year} {location} {format}.{ext}

我怎樣才能移動文件，使他們有這樣的目錄結構？

Animal stuff
├── Lion
│   ├── 2015 - Africa
│   │   ├── [Lion] 2015 Africa Book.pdf
│   │   └── [Lion] 2015 Africa Magazine.pdf

└── Tiger
   ├── 2015 - Africa
   │   ├── [Tiger] 2015 Africa Book.pdf
   │   └── [Tiger] 2015 Africa Magazine.pdf
   ├── 2015 - Asia
   │   ├── [Tiger] 2015 Asia Book.pdf
   │   └── [Tiger] 2015 Asia Magazine.pdf
   ├── 2016 - Africa
   │   ├── [Tiger] 2016 Africa Book.pdf
   │   └── [Tiger] 2016 Africa Magazine.pdf
   └── 2016 - Asia
       ├── [Tiger] 2016 Asia Book.pdf
       └── [Tiger] 2016 Asia Magazine.pdf

嘗試：

find . -maxdepth 1 -type f -exec bash -c '
   animal=${1%% *}; 
   year=${1#* }; year=${year% *};
   mkdir -p "${animal//[][]}/${year/ / - }" && mv "$animal $year"'*' "${animal//[][]}/${year/ / - }/"
' _ {} \; 2> /dev/null

結果：

$ tree
.
