• dev
  master

* `git branch <name>` 创建新分支* `git checkout <name>` 切换到分支

git checkout dev
Switched to branch ‘dev’

* `git checkout -b <name>` 创建新分支并切换

git checkout -b dev

Switched to a new branch ‘dev’

* `git merge <branch>` 把某个分支的内容合并到当前分支

$ git merge dev

* `git branch -D <branch>` 强行删除某一个分支

• 查看分支：git branch
• 创建分支：git branch
• 切换分支：git checkout
• 创建+切换分支：git checkout -b
• 合并某分支到当前分支：git merge
• 删除分支：git branch -d
• 强行删除：git branch -D

# Bug 分支* `git stash`把当前工作区的所有东西都临时存储起来并返回原始状态。

$ git stash

Saved working directory and index state WIP on master: 55f1da8 merge with no-ff
HEAD is now at 55f1da8 merge with no-ff

* `git stash list`查看被储存起来的列表

$ git stash list

stash@{0}: WIP on master: 55f1da8 merge with no-ff

* `git stash apply stash@{0}`恢复某一个保存点，并且不删除它。* `git stash drop stash@{0}`删除一个保存点* `git stach pop stash@{0}`恢复并删除某个保存点# 标签* `git tag` 查看所有标签* `git tag <tag name>` 新增标签* `git tag <tag name> <commit id>` 给某个一提交打上标签* `git show <tag name>` 显示标签信息* `git tag -a <tag name> -m <tagCommit> <commit id>` 创建带文字说明的标签* `git tag -d <tag name>` 删除标签# 远程提交## SSH Key 秘钥1. 创建SSH Key。在用户主目录下，看看有没有.ssh目录，如果有，再看看这个目录下有没有id_rsa和id_rsa.pub这两个文件，如果已经有了，可直接跳到下一步。如果没有，打开Shell（Windows下打开Git Bash），创建SSH Key：

$ ssh-keygen -t rsa -C “[e-mail]”

你需要把邮件地址换成你自己的邮件地址，然后一路回车，使用默认值即可，由于这个Key也不是用于军事目的，所以也无需设置密码。如果一切顺利的话，可以在用户主目录里找到.ssh目录，里面有id_rsa和id_rsa.pub两个文件，这两个就是SSH Key的秘钥对，id_rsa是私钥，不能泄露出去，id_rsa.pub是公钥，可以放心地告诉任何人。2. 到远程仓库中设置 id_rsa.pub 文件里的内容。作为 SSH Key## 关联远程仓库

$ git remote add origin [e-mail]:michaelliao/learngit.git

## 推送 master 分支的所有内容/// 第一次

git push -u origin master

/// 之后

git push origin master

michaelliao 是仓库名称## 克隆一个仓库

$ git clone [e-mail]:michaelliao/gitskills.git
