/etc/DIR_COLORS 파일이 있습니다.
(없는분은 복사해놓겠습니다)
 그것을 적당히 수정합니다.
그리고
 # cp /etc/DIR_COLORS ~/.dir_colors
 즉, DIR_COLORS 파일을 홈디렉토리에 .dir_colors 로 카피합니다(점 주의)
 그리고 로그아웃후 다시 로그인합니다(쉘 환경을 다시 갱신)
(로그아웃하지않고 어떻게 다시 읽어들일수있는진 잘 모르겠습니다)
 그러면 멋지게 바뀌어있습니다. ls 명령을 실행해보세요
 서로 보기좋은 dir.colors 환경을 공유한다면  컴퓨터하다가 모니터에
코박는일은 없을듯!!
 -----------다음은 DIR_COLORS 가 없는분들을 위한 것입니다 그대로 복사했습니다.-----

 # 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.
