Preliminaries

(可选) 设置SSH

Generate Key

创建ssh公钥私钥:

ssh-keygen -t ed25519

可选参数:

ssh-keygen: illegal option -- -

       ssh-keygen -Y check-novalidate -n namespace -s signature_file
       ssh-keygen -Y sign -f key_file -n namespace file [-O option] ...
       ssh-keygen -Y verify -f allowed_signers_file -I signer_identity
                  -n namespace -s signature_file [-r krl_file] [-O option]

然后将ssh pub key添加到github

Clone

将一个远程的代码仓库下载到本地, 包含版本信息(.git文件夹):

git clone <remote_url> <local_folder>

其中:

  • remote_url是远程仓库的地址, 可以是https://的url, 也可以是git@github.com:<username>/<repo>这种的ssh路径
  • 如果不指定local_folder, 那么默认创建一个repo_name的folder. 如果已经存在, 那么git clone会失败. 指定local_folder之后会将repo下载到local_folder中(创建新的文件夹)

可以指定下载的分支:

git clone <remote_url> -b <branch> --single-branch

使用--single-branch可以避免一次性将全部的分支都拉取.

可以递归拉取, 一次性clone全部的子模块:

git clone <remote_url> -r
