HDD에 파일이 있습니다.
cd /media/celebisait/5AC69788C6976355
라는 내 파일이 myFile.tar.gz있습니다. 내가 할 ls -l,
-rw------- 2 celebisait celebisait 1387745311 Jun 6 2013 myFile.tar.gz
다 괜찮아 보인다. 그러나 내가 할 때
$ sudo chmod 755 myFile.tar.gz
나는 오류가 없지만 아무 일도 일어나지 않습니다. 즉, ls -l다시 할 때 같은 결과를 얻습니다.
-rw------- 2 celebisait celebisait 1387745311 Jun 6 2013 myFile.tar.gz
Chmod는 변하지 않습니다. 왜?
