원하지 않는 줄을 제거하는 방법은 무엇입니까? while 루프?

tag-icon • tag-icon bash grep
원하지 않는 줄을 제거하는 방법은 무엇입니까? while 루프?

나는 다음 코드를 작성했습니다.

#!/bin/bash
filter(){

grep -Ev "INFO" /app/me/logs/$1

}

filter "$1" > /app/me/logs/${1}.filtered

cat /app/me/logs/${1}.filtered

그래서 그것이 하는 일은 INFO라는 단어를 포함하는 모든 줄을 제거하는 것입니다. 그러나 동시에 다음과 같은 결과가 출력됩니다.

보시다시피, 잘 작동하지만 상단에 "ERROR|FATAL|WARN"과 같은 단어가 포함되지 않은 원치 않는 줄이 있습니다. 줄은 필요하지 않지만 동시에 들여쓰기된 줄과 그 앞의 줄을 원합니다. 나는 그것이 다음과 같이 보이기를 원합니다 :

도움이 필요하세요? 감사해요,

답변1

숫자로 시작하는 첫 번째 행까지 모든 행을 필터링하려면 sed다음과 같이 GNU를 사용하십시오.

sed '1,/^[0-9]/{/^[0-9]/!d}' logfile

이 sed편집 스크립트는 /^[0-9]/!d"숫자로 시작하지 않는 모든 줄을 삭제" 하여 1,/^[0-9]/1부터 숫자( )로 시작하는 첫 번째 줄(포함)까지의 모든 줄에 적용됩니다.

INFO 줄을 추가로 필터링하려면 다음을 수행하세요.

sed -e '1,/^[0-9]/{/^[0-9]/!d}' -e '/INFO/d' logfile

따라서 귀하의 스크립트는

#!/bin/bash

function filter {
    sed -e '1,/^[0-9]/{/^[0-9]/!d}' -e '/INFO/d'
}

filter <"/app/me/logs/$1" >"/app/me/logs/$1.filtered"

filter또한 파일 이름이나 경로와 관계없이 함수를 만들었습니다 . 유일한 목적은 입력 스트림을 가져와 필터링된 스트림을 출력하는 것입니다.

다음은 왜 안 됩니까?

grep -Ev "INFO|SLF4J|201[0-9]
