Linux 드라이브 및 파일 시스템에 대해 알아보기

나는 리눅스 자동차 플레이어를 가지고 있습니다. 장치의 언어 파일을 찾아야 합니다. 장치에 메뉴가 너무 많지만 영어와 중국어만 있습니다. 예를 들어 언어, 언어, 영어, 중국어에 관한 파일이나 폴더를 찾을 수 없습니다. 여기에서 장치 비디오를 확인하세요.https://www.youtube.com/watch?v=1FQJ6_WvaZg

드라이브를 잘못 검색한 것 같습니다. 장치에 다른 드라이브가 있을 수도 있습니다. lsblk 명령을 사용하여 드라이브를 확인했습니다. 아래에서 ls 명령 출력과 lsbkl 명령 출력을 볼 수 있습니다.

lsblk 명령이 이 장치의 모든 드라이브를 표시하는지 확인할 수 있습니까? mmcblk0 드라이버란 무엇입니까? 레이블이 지정되지 않은 이 드라이브의 파일을 어떻게 볼 수 있나요? mmcblk0boot0 및 mmcblk0boot1도 있습니까?

답변1

대부분의 언어 파일은 사용 중인 배포판에 따라 /usr/lib/locale또는 에 있습니다 ./usr/share/locale

lsblk드라이브 목록과 드라이브가 설치된 위치가 제공됩니다. 정말로 알고 싶다면 mmcblk0p1언어 파일이 "드라이브"에 있어야 합니다.

그러나 루트로 변경을 시작하기 전에 Google에서 "초보자를 위한 Linux 명령줄"을 검색해 보는 것이 좋습니다.
