저는 우분투를 처음 접했기 때문에 여전히 bash 스크립트 작동 방식을 배우고 있습니다. 제가 작업해온 이 코드가 있는데 아주 잘 작동합니다. (부가 질문 - 카운트다운 섹션을 최적화할 수 있습니까? 한 번 정의한 다음 모든 섹션에서 호출합니까?) 해당 totem "/video/location/here.ext"명령을 사용할 때 내 문제는 비디오 플레이어가 하나의 비디오만 로드한다는 것입니다.
실제적인 문제totem "/video.ext": 터미널에서 명령을 사용할 때 Totem이 현재 비디오가 끝난 후 다음 비디오를 자동으로 계속하도록 하려면 어떻게 해야 합니까?
