1. Create a new repository

git clone git@gitlab.bj.sensetime.com:xxx.git
cd xxx
touch README.md
git add README.md
git commit -m "add README"
git push -u origin master

2. Push an existing folder


cd existing_folder
git init
git remote add origin git@gitlab.bj.sensetime.com:xxx.git
git add -f .
git commit -m "Initial commit"
git push -u origin master

3. Push an existing Git repository


cd existing_repo
git remote rename origin old-origin
git remote add origin git@gitlab.bj.sensetime.com:xxx.git
git push -u origin --all
git push -u origin --tags

4. Remove file

删除远端文件，保留本地文件

cd existing_dir
git rm -r --cached  yy.txt           # 将文件夹从暂存区中删除
git commit -m 'delete yy.txt'        # 将修改后的暂存区合并到HEAD中
git push origin master               # 推到远端

删除远端文件，同时删除本地和缓存区文件

cd existing_dir
git rm file_name                   # 删除本地文件, 同时也从暂存区中删除
git commit -m "delete"         # 合并到HEAD中
git push origin master

6. 远程仓库迁移

6.1 通过删除远程仓库创建新的仓库进行迁移

# 查看远程仓库
$ git remote
origin
# 重命名远程仓库
$ git remote rename origin old-origin
# 添加一个新的远程 Git 仓库
$ git remote add origin 新仓库地址
# 查看远程仓库Git保存的简写与其对应的 URL
$ git remote -v
old-origin	https://github.com/test/research-study (fetch)
old-origin	https://github.com/test/research-study (push)
origin	https://github.com/frontend/research-study (fetch)
origin	https://github.com/frontend/research-study (push)
# 删除远程仓库
$ git remote remove old-origin
# 查看是否迁移成功
$ git remote -v
origin	https://github.com/frontend/research-study (fetch)
origin	https://github.com/frontend/research-study (push)

6.2 通过重置远程仓库进行迁移

# 查看当前的远程仓库
$ git remote -v
origin	https://github.com/test/research-study (fetch)
origin	https://github.com/test/research-study (push)
# 使用git remote set-url重置为新的仓库
$ git remote set-url origin https://github.com/frontend/research-study
# 查看是否迁移成功
$ git remote -v
origin	https://github.com/frontend/research-study (fetch)
origin	https://github.com/frontend/research-study (push)
