rcity18 flag가 추가되고 삭제되었다는 commit hash log가 남아있다

 

rcity17@9947d876f6e5:~$ git checkout 2ad972449af03e66774b60cdfd3c5fbcc87b3c84
fatal: Unable to create '/home/rcity17/.git/index.lock': Permission denied

 

하지만 커밋된 hash 값을 넣어 checkout 하려고했지만 Permission denied가 떳다 하지만 다른 한가지 확인 할 수 있는 방법이 있다

 

 

바로 git show 를 이용하는 것이다

rcity17@9947d876f6e5:~$ git show 2ad972449af03e66774b60cdfd3c5fbcc87b3c84
