어제까지 자알 되던 ls 명령이 갑자기 안 먹으니
답답만 해요..  어떤 방법이 없을까요..
 [root@dns docs]# ls
ls: unrecognized option `--show-control-chars'
Try `ls --help' for more information.
[root@dns docs]# ll
ls: unrecognized option `--show-control-chars'
Try `ls --help' for more information.
[root@dns docs]# l
ls: unrecognized option `--show-control-chars'
Try `ls --help' for more information.
 모두 이렇게 나오네요...
 왜 그러죠 ???????
꼭꼭꼭 알려주세요..
