.dir_colors の設定方法

だからこのファイルを見つけました.dir_colors。だから設定し、 ~/.bashrcファイルに以下を追加しました。

if [ -x /usr/bin/dircolors ]; then
  test -r ~/.dir_colors && eval "$(dircolors -b ~/.dir_colors)" || eval "$(dircolors -b)"
  alias ls='ls --color=auto'
fi

動作しません。理由はわかりませんが、LS_COLORS変数はです''。手動で実行すると、次のdircolors -b ~/.dir_colorsように表示されます。

LS_COLORS='';
export LS_COLORS

なぜこれが起こるのかご存知ですか？

私のファイルの内容は次のとおりです.dir_colors。

# Extra command line options for ls go here.
# Basically these ones are:
#   -F   = show '/' for dirs, '*' for executables, etc.
#   -T 0 = don't trust tab spacing when formatting ls output.
#   -b   = better support for special characters
OPTIONS -F -b -T 0
