"systemctl status" 출력에서 ​​"log" 섹션 숨기기

데모의 경우 이를 사용하여 systemctl status인간 친화적인 형식으로 서비스 상태를 표시하고 로그 부분을 숨기고 싶습니다.

숨겨진 옵션이 있나요? 나는 이 -o옵션을 알고 있지만, 내가 아는 한 "빈" 형식은 없습니다.

답변1

내가 얼마나 어리석었나! 이 질문을 던진 후 영감을 받아 다음과 같이 시도해 보았습니다.

systemctl --lines 0 status ssh.service

   -n, --lines=
       When used with status, controls the number of journal lines to show, counting from the
       most recent ones. Takes a positive integer argument. Defaults to 10.

이것이 이런 식으로 작동해야 하는지 여부 man(n은긍정적인, 포함 여부는 확실하지 않습니다.영), --lines=0설정에 관계없이 로그(빈 구분선 포함)를 완전히 삭제합니다.
