Local Repository

• 지역 저장소

Remote Repository

• 원격 저장소
• github 도 원격 저장소 중 하나

대략 흐름
Local Repository1 --push--> Remote Repository
Local Repository2 <--clone-- Remote Repository
Local Repository2 --push--> Remote Repository
Local Repository1 <--pull-- Remote Repository
Local Repository1 --push--> Remote Repository
Local Repository2 <--pull-- Remote Repository

원격 저장소와 연결

git remote add 원격저장소별칭 원격저장소주소

• 원격 저장소와 연결
• 별칭은 하나의 지역 저장소는 여러 원격 저장소와 연결 가능하므로 이름 지정

$ git remote add origin https://github.com/~~~/git-study.git


$ git remote
origin


$ git remote -v
origin  https://github.com/~~~/git-study.git (fetch)
origin  https://github.com/~~~/git-study.git (push)

원격 저장소에 업로드

git push

• 연결 후, 최초는 설정 필요
• git push --set-upstream origin main: 지역 저장소는 앞으로 git push 명령어만 입력하면 origin의 main 브랜치에 기본적으로 push되는 것

$ git push
fatal: The current branch main has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin main

To have this happen automatically for branches without a tracking
upstream, see 'push.autoSetupRemote' in 'git help config'.


$ git push --set-upstream origin main

다른 로컬에 복제

• 다른 컴퓨터에 원격 저장소의 내용을 복제하여 로컬 저장소 만들기
• Clone = init + pull

git clone 원격저장소주소

• 해당 폴더에 git-study 라는 디렉토리가 생성됨

$ git clone https://github.com/~~~/git-study.git

로컬 저장소에 다운로드

• 원격 저장소의 내용을 로컬 저장소에 내용 동기화

git pull

• 컴퓨터2 에서 작업하고 push로 내용 원격 저장소로 업로드

$ vi hello.txt

$ git status
