4 | sed 는 필요에 따라 사용할 수 있는 함수를 제공하지 않기 때문에 모든 문제를 regex 과 몇 개의 sed 명령을 이용해서 해결해야 합니다.
5 | 그래서 처음 sed 를 사용할 때는 어떻게 처리해야 될지 방법이 잘 떠오르지 않는 경우가 많은데요.
6 | 명령이 몇 개 안되고 구조가 간단하다고 해서 사용방법까지 간단하지 않은 걸 알 수 있습니다.
7 |
8 | 함수가 많다는 것은 다시 말하면 문제를 쉽게 해결할 수 있는 방법이 많다고도 할 수 있습니다.
9 | 함수가 정형화된 기법이라면 sed 는 함수를 제공하지 않기 때문에 몇가지 자주 사용되는 기법들을 알고 있어야 하는데요.
10 | 그러기 위해서는 실제로 문제를 여러개 풀어보는 것이 좋습니다.
11 | stackoverflow.com 나 unix.stackexchange.com 같은 Q&A 사이트에서
12 | sed 태그로 검색을 해보면 관련된 질문과 답변들을 볼수 있는데 정말 생각지도 못한 방법으로 문제를 해결하는 분들이 있습니다.
13 |
14 | 시간을 내어서 문제를 풀다 보면 "sed 로 처리할 수 있는게 몇 개 안돼.." 에서 "대부분 sed 로 처리가 가능하네.."
15 | 로 바뀌게 될 것이라고 생각합니다.
16 |
17 |
18 | > sed 버전이 4.2.2 에서 4년 만에 4.4 로 업데이트 되었습니다.
19 | > regex 매칭 속도가 10배 빨라졌다고 하는데요. 현재 대부분의 시스템에는 4.2.2 버전이 설치되어 있을 텐데
20 | > https://packages.debian.org/sid/amd64/sed/download 에서 deb 패키지를 다운로드하실 수 있습니다.

473 | sed 는 제공하는 명령이 몇개 되지 않기 때문에 원하는 결과를 얻기 위해서는
474 | sed 가 가지고 있는 기본 기능을 최대한 활용해야 합니다.
475 | 이때 각 명령들이 하는 역할을 명확하게 알고 있지 못하면 활용하기가 어렵습니다.
476 | sed 는 모든 텍스트 조작을 regex 을 이용해 합니다.
477 | 그러므로 regex 을 잘 알고 활용할 수 있으면 sed 를 사용하는 것이 어렵지 않습니다.
478 | sed 를 하게 되면 좋은점 또한 regex 을 활용하는 법을 배울 수 있다는 점입니다.
479 | 아래는 sed 에서 사용되는 명령들인데요. 보기에는 많은것 같지만 대, 소문자로 중복되는 기능,
480 | 잘 사용하지 않는 명령들을 제외하면 실제 사용되는 명령은 몇개 되지 않습니다.

471 | Introduction
472 | Shell 에서 제일 중요하고 기본이 되는 명령이 sed 입니다.
473 | 왜냐하면 모든 명령의 텍스트 출력을 sed 를 이용해 컨트롤할 수 있기 때문입니다.
474 | Unix 운영체제가 처음 만들어졌을 때 3 가지 주요 구성요소가 assembler, editor, shell 이였는데요.
475 | 당시에는 컴퓨터가 메모리도 적고, 모뎀 속도도 느리고, 콘솔로 teletype 같은
476 | 라인 프린터 를 사용했기 때문에 라인 에디터를 사용하였습니다.
477 | 현재 리눅스에서도 볼수있는 /bin/ed 명령이 라인 에디터인데요.
478 | 이 라인 에디터가 이후에 sed, ex, vi, grep 같은 명령들의 기반이 됩니다.
479 | sed 는 ed 명령의 stream 버전으로 대부분 명령과 사용방법이 같습니다.
480 |
481 | ex 명령은 ed 명령의 확장 버전으로 vi 에서 : 를 이용한 command mode 로 사용됩니다. 실제적으로 ex 명령의 visual mode 버전이 vi 입니다.
482 |
483 | 필요에 따라 수시로 업데이트 되므로 파일을 다운로드하는 것보다는 웹에서 보는 것이 좋습니다.
484 | 흰색 바탕이 너무 밝을 경우 좌측 상단에 보면 어두운 바탕으로 테마를 변경할 수 있습니다.
485 | ( 참고로 페이지는 Night 모드에서 작성하였습니다. )

474 | 1. 현재 pattern space 에 있는 내용을 프린트합니다.
475 | p 명령은 주로 -n 옵션과 함께 사용됩니다.
476 | -n 옵션을 사용하지 않은 상태에서 p 명령을 사용하면 p 명령에 의해 한번,
477 | 명령 사이클이 끝날때 sed 에 의해 한번, 두번 pattern space 의 내용이 출력됩니다.
478 | $ seq 111 111 555 | sed '3p'

486 | 라인이 pattern space 에 입,출력 되는 과정
487 |
488 | 새로운 명령 사이클이 시작되거나 아니면 n, N 명령에 의해
489 | 입력 스트림으로 부터 라인이 하나 pattern space 에 입력되면 위 그림에서 1번 상태가 됩니다.
490 | 이때 한가지 주목해야 될 점은 newline 이 pattern space 밖으로 제외된다는 점입니다.
491 | 그러므로 수정 명령이 적용될때 newline 은 포함되지 않습니다.
492 | 사용자가 입력한 명령들이 pattern space 에 적용되고 명령 사이클이 끝나거나, 아니면
493 | 사이클 중에 p 명령을 실행했을 경우 그림 2번 에서와 같이 현재 pattern space 에 있는 내용과
494 | 제외되었던 newline 더해져서 출력됩니다.
495 | 위의 경우는 입력되는 라인에 newline 이 포함되는 일반적인 경우에 해당합니다.
496 | 가령 bash 에서 echo -n 111 명령을 사용하게 되면 출력에 newline 이 포함되지 않게 되는데요.
497 | 이때는 sed 명령의 출력에도 newline 이 포함되지 않게 되므로 개행이 되지 않습니다.
498 | $ echo 111 | sed ''
499 | 111
500 | mug896@EliteBook [pts/7 ] ~/tmp
501 |
502 | $ echo -n 111 | sed ''
503 | 111 mug896@EliteBook [pts/7 ] ~/tmp
504 | $
505 |
506 | 명령 사이클이 끝나거나, p 명령에 의해서 pattern space 에 있는 내용이 프린트될 때는
507 | 현재 pattern space 에 있는 전체 내용이 프린트됩니다.
508 |
509 |
510 | 1. pattern space 에서 첫번째 라인만 프린트합니다.
511 | pattern space 에 라인이 하나뿐이 없으면 p 명령과 차이가 없습니다.
512 | 이 명령은 주로 multiple lines 를 다룰 때 pattern space 에서 첫 번째 라인을 삭제하는 D 명령과 함께 사용됩니다.

472 | Debugging
473 | sed 는 따로 디버깅을 위한 옵션이나 기능을 제공하지 않습니다.
474 | 따라서 디버깅을 하려면 직접 p 명령을 이용해서 pattern space 에 있는 내용을 조회해야 하는데요.
475 | 그런데 p 명령은 printable 문자만 표시되기 때문에 내용 중에
476 | non-printable 문자가 사용됐을 때는 정확한 값을 확인할 수가 없습니다.
477 | 따라서 sed 는 디버깅에 활용할 수 있도록 다음과 같은 명령을 제공합니다.
478 |
479 | pattern space 에 있는 내용을 escape sequence 를 이용해 표시해줍니다.
480 |
481 |
482 | $ echo -e "valX\a111\nvalY\t222\nvalZ\v333" | sed -En 'N;N;p'
483 | valX111
484 | valY 222
485 | valZ
486 | 333
487 |
488 |
489 | $ echo -e "valX\a111\nvalY\t222\nvalZ\v333" | sed -En 'N;N;l'
490 | valX\a111\nvalY\t222\nvalZ\v333$
491 |
492 |
493 | l 명령은 출력이 newline 문자에 의해 개행이 되지 않기 때문에 따로 line-wrap length 값을 사용해 개행하는데요.
494 | sed 명령의 -l N 옵션 을 통해서 값을 설정할 수 있습니다.
495 |
496 | l 명령을 활용한 디버깅 예제
497 | 다음은 데이터 파일에 숫자 라인과 알파벳 라인이 혼합되어 있을 경우
498 | 숫자 라인 다음에 알파벳 라인이 올 경우만 값을 표시하는 스크립트입니다.
499 | 이때 l 명령을 이용함으로써 매 라인 입력 시마다 변경되는 pattern space 의 값을
500 | 조회해 볼수 있습니다.

474 | 1. pattern space 에 있는 내용을 전부 삭제합니다.
475 | 2. pattern space 에 데이터가 없으므로 명령 사이클을 중단하고 다음 사이클을 시작합니다.
476 | 3. 읽어들일 라인이 없으면 exit 합니다.
477 | d 명령을 사용할 때 기억해야 될 것은 명령이 실행되면 현재 사이클이 중단되고
478 | 새로운 사이클을 시작한다는 것입니다. 만약에 pattern space 삭제후 현재 위치에서
479 | 실행을 계속하려면 z 명령 을 사용할 수 있습니다.
480 |
481 |
482 | 1. pattern space 에서 첫 번째 라인을 삭제합니다.
483 | 2. 명령 사이클의 BEGIN 위치로 가서 다음 사이클을 시작합니다. ( 이때 라인을 읽어들이지 않습니다 )
484 | 3. pattern space 에 라인이 하나만 남았을 경우는 d 명령과 같은 역할을 합니다.
485 | 이 명령은 multiple lines 을 처리할 때 사용하는 명령으로 pattern space 에 라인이 하나만
486 | 남았을 경우는 삭제되면 이어지는 명령에서 처리할 데이터가 없으므로 d 명령과 같은 역할을 합니다.

472 | AND, OR, NOT
473 | sed 는 간단히 사칙연산을 할 수 있는 연산자도 없을뿐더러 AND, OR 연산자도 없습니다. 하지만 sed 의 기본기능을 활용하면 AND, OR 연산을 처리할 수가 있습니다.
474 | AND
475 | AND 연산은 보통 프로그래밍 언어에서 && 연산자로 표현되는데요. sed 에서는 다음과 같은 방식으로 AND 연산 결과를 얻을 수 있습니다.
476 | AA && BB
477 | $ echo "AA 11 BB 22 CC" | sed -n '/AA/{ /BB/p }'
478 | AA 11 BB 22 CC
479 |
480 | AA && BB && CC
481 | $ echo "AA 11 BB 22 CC" | sed -n '/AA/{ /BB/{ /CC/p } }'
482 | AA 11 BB 22 CC
483 |
484 | OR
485 | OR 연산은 프로그래밍 언어에서 || 연산자에 해당하는데요. sed 에서는 regex 에서 제공하는 | 연산자를 이용할 수 있습니다.
486 | AA || BB
487 | $ echo "11 BB 22 CC 33" | sed -En '/AA|BB/p'
488 | 11 BB 22 CC 33
489 |
490 | $ echo "11 BB 22 CC 33" | sed -En -e '/AA/{bX}; /BB/{bX}; b' -e ':X p'
491 | 11 BB 22 CC 33
492 |
493 | AA || BB || CC
494 | $ echo "11 CC 22 DD 33" | sed -En '/AA|BB|CC/p'
495 | 11 CC 22 DD 33
496 |
497 | $ echo "11 CC 22 DD 33" | sed -En -e '/AA/{bX}; /BB/{bX}; /CC/{bX}; b' -e ':X p'
498 | AA 11 BB 22 CC
499 |
500 | AND, OR
501 | AA && ( 11 || 22 )
502 | $ echo "AA 22 BB 33 CC" | sed -En '/AA/{ /11|22/p }'
503 | AA 22 BB 33 CC
504 |
505 | AA && BB && ( 11 || 22 || 33 )
506 | $ echo "AA 33 BB 44 CC" | sed -En '/AA/{ /BB/{ /11|22|33/p } }'
507 | AA 33 BB 44 CC
508 |
509 | AA || ( 11 && 22 )
510 | $ echo "BB 11 CC 22 DD" | sed -En -e '/AA/{bX}; /11/{ /22/{bX} }; b' -e ':X p'
511 | BB 11 CC 22 DD
512 |
513 | AA || BB || ( 11 && 22 && 33 )
514 | $ echo "11 CC 22 DD 33" | sed -En -e '/AA|BB/{bX}; /11/{ /22/{ /33/{bX} } }; b' -e ':X p'
515 | 11 CC 22 DD 33
516 |
517 | NOT
518 | /.../ 뒤에 ! 문자를 붙이면 logical NOT 이 됩니다.
519 |
520 | $ echo "goobar 111 222" | sed -E '/^foo/! s/^|$/X/g'
521 | Xgoobar 111 222 X
522 |
523 |
524 | $ echo "goobar 111 222" | sed -E '/^foo/! { s/^|$/X/g; s/111/aaa/ }'
525 | Xgoobar aaa 222 X
526 |
527 | $ echo "foobar 111 222" | sed -E '/^foo/! s/^|$/X/g'
528 | foobar 111 222
529 |
530 |
531 | sed -En '/^\s*$|^#/!p'
532 |
533 | sed -En '/^\s*$/!{ /^#/!p }'
534 |
535 | sed -En '/^#/!{ /^\s*$/!p }'
