nosuid를 사용하여 마운트되지 않은 NFS 파일 시스템을 찾기 위한 정규식(특별한 요구 사항이 없는 한)

nosuid를 사용하여 마운트되지 않은 NFS 파일 시스템을 찾기 위한 정규식(특별한 요구 사항이 없는 한)

mount -v 2>/some/file명령을 실행 한 후 다음 정규식을 사용하여 다른 스크립트로 구문 분석하는 스크립트가 있습니다 .

^.*[\ \t]+type[\ \t]+nfs(?![\ \t]+.*\b(?:nosuid|nosetuid)\b).*

내가 겪고 있는 문제는 마운트를 방지하는 예외가 있는 일부 NFS 마운트가 있다는 것입니다 nosuid(Solaris 11 IPS 저장소입니다). 이제 알려진 설치를 제외하도록 정규식을 수정해야 합니다...

참고로 다음은 몇 가지 샘플 출력입니다 mount -v.

다음과 같이 일치하는 줄의 시작 부분에 있는 설치를 기반으로 IP별 설치를 제외하도록 정규식을 수정해 보았습니다.

^(.*|[^sample])[\ \t]+type[\ \t]+nfs(?![\ \t]+.*\b(?:nosuid|nosetuid)\b).*

그러나 이것은 작동하지 않습니다 ...

답변1

이 정규식으로 무엇을 하고 있는지 잘 모르겠지만 나에게는 괜찮은 것 같습니다. Perl인 것 같아서 GNU 버전의 grep -P스위치를 사용하여 다음과 같이 정규식을 사용했습니다.

$ column -t mount.txt | \
     grep -vP '^(.*|[^sample])[\ \t]+type[\ \t]+nfs(?![\ \t]+.*\b(?:nosuid|nosetuid)\b).*'

예

$ column -t mount.txt | \
     grep -vP '^(.*|[^sample])[\ \t]+type[\ \t]+nfs(?![\ \t]+.*\b(?:nosuid|nosetuid)\b).*'
