[Git] 두 개의 저장소 합치기(merge two git repositories)

깃(Git)의 두 개의 저장소(Repository)를 합치는 방법은 다음과 같습니다.

$ git clone https://gitlab.myhost.net/remain_project.git # 합친 후, 남겨질 프로젝트 저장소 복사
# cd remain_project/ # 저장소 폴더로 이동

$ git config --local user.email "hanwhhanwh@gmail.com" # 저장소의 사용자 이메일 주소 등록
$ git config --local user.name "Wonhee Han" # 저장소의 사용자 이름 등록

$ git remote add added_project https://gitlab.myhost.net/added_project.git # 합칠 저장소
$ git fetch added_project --tags # 모든 태그 및 브랜치를 가져옵니다.
