답변1

awk버전:

#!/usr/bin/awk -f

function output(name,WWN,objectID) {
  for (x in WWN) {
    for (y in objectID) {
      print name, x, y;
    }
  }
}

BEGIN {
  FS = "=";
}

{
  if ($1=="name") {
    output(name,WWN,objectID);
    name = $2;
    delete WWN;
    delete objectID;
  }
  if ($1=="WWN") {WWN[$2]=$2}
  if ($1=="objectID") {objectID[$2]=$2}
}

END {output(name,WWN,objectID)}

답변2

이것은 간단한 Perl 스크립트입니다:

#!/usr/bin/perl -n
#

sub printall {
    foreach my $wwn (@wwns) {
        foreach my $obj (@objects) {
            print "$name $wwn $obj\n";
        }
    }
}

if (/name=(.*)/) {
    if ($name) {
        printall;
    }
    $name = $1;
    @wwns = ();
    @objects = ();
} elsif (/WWN=(.*)/) {
    push @wwns, $1;
} elsif (/objectID=(.*)/) {
    push @objects, $1;
}

END {
    printall;
}

파일의 행을 반복하면서 WWNs와 objectIds를 수집합니다. 그러다가 name=파일 끝에 라인이 나올 때마다 수집된 내용을 예제 순서대로 출력한다.
