次のような構造のファイルがたくさんあります。

[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

など。

デフォルトでは、これらのファイルは次のパターンに従います。[{animal}] {year} {location} {format}.{ext}

このようなディレクトリ構造を持つようにファイルをどのように移動できますか？

努力する：

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
