• 远程 github 中已加载 id_rsa.public(settings -> Access -> SSH &GPG keys)

INIT

• git init
  • 在当前目录下建立 .git 目录

git config --global user.name ldscfe
git config --global user.email [email protected]
git config --global color.ui true   # git status等命令自动着色

# git config --list

# 自动判断提交位置（clone多个库）
git config --global push.default matching

Repository

# clone 远程仓库
git clone [email protected]:ldscfe/pangolin.git

# token
Settings -> Developer Settings -> Personal access tokens -> tokens(classic)
# 记录 token
git clone https://<Token Name>:<Token>@github.com/ldscfe/devudefj2.git

# 刷新
git pull

# 增加文件
git status           # 查看文件状态

git add $FN
git add .            # 所有

# 提交 (需要 git add)
git commit -m "comment content"
git push

# 去除文件&目录: .gitignore，已 git add 的文件，在 .gitignore 中标识无效
log/
target/
src/test/
.DS_Store
.gitignore

git rm -f ${FN}      # 已 git add 的文件，删除后.gitignore 中标识有效

# 分支之间切换、恢复文件、创建新分支等
git checkout <branch-name>           # 从当前分支切换到指定的分支 <branch-name>, 或主分支：master
git checkout -                       # 快速切换回前一个分支
git checkout -- <file>               # 将指定文件 <file> 恢复到最新的提交状态，丢弃所有未提交的更改
git checkout -b <new-branch-name>    # 创建一个新分支 <new-branch-name> 并切换
...

# Creating remote repositories
git remote add ldscfe_cpp [email protected]:ldscfe/cpp.git
git remote add ldscfe_pangolin [email protected]:ldscfe/pangolin.git

Error

RSA 证书无或错误

ERROR: Permission to XXX/XXX.git denied to deploy key
fatal: Could not read from remote repository.
-.OR.-
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

1. repository 下 settings/Deploy keys 中有相应 RSA publickey
2. 客户端中 .ssh 中有相应的 id_rsa(MacOS 使用 ssh-add)
3. 不同的 repository 使用不同的 RSA publickey

分支冲突，本地版本陈旧

Automatic merge failed; fix conflicts and then commit the result.

丢弃本地分支内容

git reset --hard origin/master

首次推送

clone 后，首次 git push 出现:
No refs in common and none specified; doing nothing.
Perhaps you should specify a branch.

未指定推送到哪个分支，一般发生在首次推送。

git push origin master

git init

fatal: Not a git repository (or any of the parent directories): .git

git remote add 时出现，原因：未 git init

repository 不存在或无权限

git pull 时出现:
ssh_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.
