grep -v는 문자열을 제외하지 않습니다.

tag-icon • tag-icon grep find pipe
grep -v는 문자열을 제외하지 않습니다.

원하지 않는 특정 단어가 포함된 문자열을 제거하여 캡처할 플래그의 범위를 좁히려고 했기 때문에 다음을 사용했습니다.

cat $(find / -size 33c -group bandit6 -user bandit7) | grep -v 'Permission'

하지만 내 결과는 결국

그럼 이게 $()문제인거 같네요

cat $(find / -size 33c -group bandit6 -user bandit7) 2>/dev/null

하지만 작동하지 않습니다

cat $(find / -size 33c -group bandit6 -user bandit7 2>/dev/null)

grep -v괄호 안에 stderr과 섞일 수도 있다고 생각합니다.
