뭔가 이상한 걸 발견했어요. 일반 사용자로 명령을 실행하면 file항상 잘못된 시스템 호출 오류가 발생합니다.
예를 들어다루기 힘든:
$ file ~/.zshrc
[1] 18553 invalid system call file ~/.zshrc
$ file ~/.bashrc
Bad system call
이는 객체 파일, wm 환경(tty에서도 발생)에 의존하지 않으며 쉘에 의존하지 않는 것 같습니다.
이 오류를 방지하는 유일한 방법은 명령을 루트로 실행하거나 다음 명령을 사용하는 것입니다 sudo.
$ sudo file ~/.bashrc
/home/user/.bashrc: ASCII text
예상되는 동작처럼 보이지 않습니다. 이 문제의 원인이 무엇인지 아는 사람이 있습니까?
디버깅을 계속하는 방법을 모르겠습니다. 이 명령과 직접 관련된 내용을 찾지 못했기 때문에 의견이나 링크가 도움이 될 수 있습니다. file이 명령의 영향을 받는 명령은 하나인 것 같습니다.

나를 위한 한 가지 해결책은 컴파일하는 것이었습니다.시스템 애플리케이션/파일USE 플래그를 사용하여 패키지를 비활성화합니다. 또 다른 접근 방식은 seccompUSE 플래그와 USE 플래그를 모두 활성화하여 패키지를 컴파일하는 것입니다.seccomplzma
에서 equery uses file:
lzma : Support for LZMA (de)compression algorithm
seccomp : Enable seccomp (secure computing mode) to perform system call
filtering at runtime to increase security of programs
이는 업스트림의 버그인 것 같습니다.https://bugs.gentoo.org/771096
