dircolors
lsコマンドの実行時のファイルの表示色を指定する．ヂィレクトリ内のファイル一覧をlsコマンドで表示する際に，--colorオプションを指定することで，ファイルの種類やパーミッションにより色を変えて表示する．dircolorsコマンドとこれに渡す設定ファイルを用いることで，さらに細かい指定が可能となる．
設定ファイルを作成後，以下のコマンドを実行することで，設定が反映される．
$ eval `dircolors [config-file] -c`
私の設定ファイルを以下に示す．ディレクトリ，デバイスファイル，パイプなどの色分けに加え，通常ファイルの中でも，拡張子で色分けするよう記述している．
# Configuration file for the color ls utility # This file goes in the /etc directory, and must be world readable. # You can copy this file to .dir_colors in your $HOME directory to override # the system defaults. # COLOR needs one of these arguments: 'tty' colorizes output to ttys, but not # pipes. 'all' adds color characters to all output. 'none' shuts colorization # off. COLOR tty # 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.
