오류 발생 시 rsync가 반환되지 않습니다.

udev 규칙에서 백업 스크립트를 실행 중입니다. 스크립트는 rsync를 사용하여 새로 연결된 USB 드라이브에 데이터를 로드하고 복사합니다.

/home/gauthier/tmp/I_came_here그런데 생성해야 할 파일이 touch존재하지 않습니다. 그 뒤에도 뭔가가 있었는데 touch, 그것도 실행되지 않은 것 같았습니다.

rsync오류가 있어도 반환하면 안되나요? 반품이 불가능한 이유는 무엇입니까?

bash 프롬프트에서 스크립트를 실행해 보았지만(udev 규칙이 실행되도록 하는 대신) rsync.
