lsの色変える

MacにiTerm2入れてls押すと、文字が真っ白。どれがディレクトリか分からん。

そんな時はlsに-Gのオプションつければ色が付きます。
aliasにしとこう！！

ただ、そのままやと色見にくい。 例えば.bash_profileに

export LSCOLORS=gxfxcxdxbxegedabagacad  

こんな感じで書くと色が変わります。 意味は以下のとおり

LSCOLORS        The value of this variable describes what color to use
                     for which attribute when colors are enabled with
                     CLICOLOR.  This string is a concatenation of pairs of the
                     format fb, where f is the foreground color and b is the
                     background color.

                     The color designators are as follows:

                           a     black
                           b     red
                           c     green
                           d     brown
                           e     blue
                           f     magenta
                           g     cyan
                           h     light grey
                           A     bold black, usually shows up as dark grey
                           B     bold red
                           C     bold green
                           D     bold brown, usually shows up as yellow
                           E     bold blue
                           F     bold magenta
                           G     bold cyan
                           H     bold light grey; looks like bright white
                           x     default foreground or background

                     Note that the above are standard ANSI colors.  The actual
                     display may differ depending on the color capabilities of
                     the terminal in use.

                     The order of the attributes are as follows:

                           1.   directory
                           2.   symbolic link
                           3.   socket
                           4.   pipe
                           5.   executable
                           6.   block special
                           7.   character special
                           8.   executable with setuid bit set
                           9.   executable with setgid bit set
                           10.  directory writable to others, with sticky bit
                           11.  directory writable to others, without sticky
                                bit

                     The default is "exfxcxdxbxegedabagacad", i.e. blue fore-
                     ground and default background for regular directories,
                     black foreground and red background for setuid executa-
                     bles, etc.

要するに、変えたい属性の順番のところの文字を良い感じのアルファベットに変えればいいんですね。 -Gオプションのデフォルトは

exfxcxdxbxegedabagaca

だそうです。
