특정 정보를 구문 분석

Linux 시스템에서 명령을 실행하고 출력을 파일로 리디렉션하고 있습니다. 내 파일은 다음과 같습니다.

        connection-0: frdp::Purple::Test

Purple에 대한 연결만 표시하는 클라이언트 호스트 이름과 연결이 없는 클라이언트를 새 파일로 추출하고 싶습니다. 다음을 사용하여 관련 없는 정보를 모두 성공적으로 얻었습니다.

awk -F '\t' '/^client: / || /connection/' myfile1 >> myfile2

보라색으로 연결되어 있거나 연결이 없는 클라이언트만 추출할 수는 없습니다. 클라이언트가 보라색에 연결되어 있더라도 녹색에 연결된 모든 것을 무시하고 싶습니다.

편집: 이것은 awk를 사용할 때 얻는 결과입니다.

        connection-1: frdp::Green::Test
        connection-0: frdp::Purple::Test

        connection-0: frdp::Purple::Test

편집: 나는 내 모호함을 고려하지 않았습니다. 내가 찾고 있는 출력은 다음과 같아야 합니다.

tc-abcdefgh-igjk-lmno-pqrs-abcdefgh
tc-abcdefgh-igjk-lmno-pqrs-ijklmnop
tc-abcdefg-higj-klmn-opqr-qrstuvwx
tc-abcdefg-higj-klmn-opqr-09876543
tc-abcdefgh-igjk-lmno-pqrs-08649753

저는 Purple에만 연결되어 있지만 연결되지 않은 5개의 클라이언트를 원합니다.

답변1

모든 Unix 시스템의 모든 쉘에서 awk를 사용하십시오.

$ cat tst.awk
$1 == "client:" {
    prt()
}
/connection/ {
    gotConns = 1
    if ( /Purple/ ) {
        gotTarget = 1
    }
    else {
        gotOther = 1
    }
}
$1 == "hostname:" {
    host = $2 ORS
}
END {
    prt()
}

function prt(   found) {
    if ( (gotTarget && !gotOther) || !gotConns ) {
        printf "%s", host
    }
    host = gotConns = gotTarget = gotOther = ""
}


$ awk -f tst.awk file
tc-abcdefgh-igjk-lmno-pqrs-abcdefgh
tc-abcdefgh-igjk-lmno-pqrs-ijklmnop
tc-abcdefgh-igjk-lmno-pqrs-qrstuvwx
tc-abcdefgh-igjk-lmno-pqrs-09876543
tc-abcdefgh-igjk-lmno-pqrs-08649753

답변2

내가 올바르게 이해했다면:

$ tr -s '\n' ' ' < file | \
  sed 's/client:/\n/g' | \
  grep -o 'hostname: [^ ]\+ connection-0.*Purple\|hostname: [^ ]\+ $' | \
  cut -d' ' -f2
tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

  • $ tr -s '\n' ' '파일을 단일 문자열로 변환합니다.

  • sed 's/client:/\n/g'"클라이언트"를 개행 문자로 바꾸십시오.

  • grep -o 'hostname: [^ ]\+ connection-0.*Purple\|hostname: [^ ]\+ $'"connection-0...Purple"이 있는 라인이나 연결이 없는 라인을 캡처합니다.

    hostname: tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx connection-0: frdp::Purple
hostname: tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx 
hostname: tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx connection-0: frdp::Purple
hostname: tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx connection-0: frdp::Purple
hostname: tc-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx connection-0: frdp::Purple

  • cut -d' ' -f2호스트 이름만 인쇄합니다.

새 파일을 쓰려면 > newfile.
