awk를 사용하여 동적 위치에서 데이터 가져오기

awk를 사용하여 동적 위치에서 데이터 가져오기

일부 코드를 컴파일했지만 오류가 많아 소스 파일 경로, 줄 번호, 정의되지 않은 참조 등 몇 가지 사항을 보여주는 테이블을 만들고 싶습니다. 간단한 awk를 사용하여 첫 번째와 두 번째를 파내고 $1,$2 등을 인쇄하는 것은 큰 문제가 아니지만 정의되지 않은 참조는 출력의 다른 위치에 나타나기 때문에 문제가 됩니다.

다음은 내가 작성하려는 스크립트로 구문 분석하려는 오류 로그의 일부입니다.

보시다시피 1행과 14행은 다른 행과 비교하여 다른 위치에 정의되지 않은 참조를 표시합니다.

정확한 위치를 무시하지만 여전히 정의되지 않은 참조의 값을 표시하는 awk를 실행하는 방법이 있습니까?

답변1

예제 출력은 "정의되지 않은 참조"가 항상 awk줄의 마지막 필드임을 나타냅니다. 에서는 awk가 NF필드 수이고 $NF그 수가 "필드 수"인 필드가 됩니다. 마지막 필드는 귀하가 요청한 것입니다.

awk '{print "undefined reference = " $NF}'

Perl을 사용해도 괜찮다면:

perl -pe 's/^(.*?):(\d+): error: undefined reference to (.*)/\1\t\2\t\3/g'

나는 sed via를 사용하여 그것을 해냈습니다.
