Bash를 사용하여 텍스트 기반 퀴즈를 구현하는 방법은 무엇입니까?

Question

제가 생각해낸 퀴즈 프레임워크는 아래와 같습니다.GitHub(원래 사용자 GitHub 페이지는 더 이상 존재하지 않습니다).

다소 복잡해 보이기 때문에 작동 방식에 대해 설명하는 것이 좋습니다.

스크립트에는 지금까지의 모든 릴리스의 Ubuntu 버전과 코드명이 두 개의 배열에 저장되어 있습니다. 그런 다음 변수가 초기화됩니다.밖의C 스타일 표기법을 사용하여 루프에서 필요에 따라 증가할 수 있습니다 (( var++ )).

그런 다음 질문 번호에 대한 또 다른 배열을 만듭니다. 이 경우 19개 질문에 대해 0부터 18까지 포함해야 합니다.

questions_order=(15 4 1 10 8 3 13 0 11 16 2 7 5 17 6 9 14 18 12)

그런 다음 shuf새 배열을 사용하여 섞고 이를 특정 스크립트 실행에 사용합니다.

shuffled_order=( $(shuf -n19 -e ${questions_order[@]}) )

이 작업을 수행해야 합니다.밖의루프는 한 번만 실행되기를 원하기 때문입니다.

즉, 현재 질문 수가 변수와 같아질 때까지 루프가 실행되고 "${target_questions}"결과가 제공됩니다.

사용자가 질문에 응답하면 해당 내용은 설명문의 다양한 조건에 따라 해석됩니다 case. 미답(공백), 오답, 정답, 합격을 모두 감지하여 응답을 받으며, 다양한 변수가 모두 증가됩니다(예: 오답의 경우 (( wrong++ ))).

마지막 질문에 대한 답변이 완료되면 정답, 오답 및 합격 횟수(있는 경우)가 전달되고 소요 시간도 제공되는 사용자의 성과가 평가됩니다.

이것은 간단한 설명이지만 스크립트 자체에는 작업을 명확하게 만드는 다양한 주석이 있습니다! 수도나 국가 등 다른 유형의 퀴즈에도 적용할 수 있습니다.

스크립트를 파일에 복사한 후 실행 가능하게 만들고( chmod u+x), 실행하거나 폴더 ./scriptname에 넣고 ~/bin다른 프로그램처럼 이름으로 호출 ~/bin합니다 PATH.
