6장 완료후 책의 끝까지 유용하게 사용하는 스크립트

사용법:
auto-lfs s : chroot 실행, 필요한 시스템 디렉토리 마운트
auto-lfs c : chroot 종료후 불필요한 시스템 디렉토리 마운트 해제

다음과 같이 등록하고 사용해야 cd 가 작동을 합니다.

alias <filename>='source <filename>'

다운로드 링크 입력: 다운로드 → 압축 해제 → 디렉토리 이동

추가한 사항

1. 입력받은 URL이 Git인 경우 처리 추가
2. 확장자가 .zip인 경우 처리 추가
3. 이미 다운로드 완료한 파일의 경우 처리 추가
4. 작업 디렉토리의 소유권 확인 추가
5. 출력 색상 변수 설정

추가할 사항

1. alias 등록 확인
2. wget, git, gawk 설치 여부 확인

수정할 사항

1. git clone 사용 할 때 작업 디렉터리에 먼저 받고 source 디렉터리에 복사하는 방식으로 변경 필요.
