ld-linux.so를 사용하여 프로그램을 실행하는 방법은 무엇입니까?

동적 링커가 실행될 수 있습니다.일부 동적 링커 또는 공유 객체를 실행하여 간접적으로(이 경우 명령줄 옵션이 동적 링커에 전달될 수 없으며 ELF의 경우 프로그램의 .interp 섹션에 저장된 동적 링크가 장치에서 수행됨) 또는직접 실행:

/lib/ld-linux.so.* [옵션] [프로그램 [매개변수]]

그런데 막상 해보니,

$ LD_DEBUG=libs /usr/lib/ld-linux.so.2 ls
     23325: find library=ls [0]; searching
     23325:  search cache=/etc/ld.so.cache
     23325: 
ls: error while loading shared libraries: ls: cannot open shared object file

$ LD_DEBUG=libs ls
     23503: find library=libcap.so.2 [0]; searching
     23503:  search cache=/etc/ld.so.cache
     23503:   trying file=/usr/lib/libcap.so.2
...

내가 뭘 잘못했나요? ld-linux.so프로그램을 직접 실행하는 방법이 있나요 ?

전체 경로를 사용해 보세요 ls.
