2.1 基本

git init 初始化代码仓库
git status 查询仓库索引状态

git config --global user.name “Your Name” 配置全局的提交者名字
git commit -m “add component to project " --author=” Your Name < [email protected]>" 提交暂存内容（不带文件名的提交）
git commit somefile 提交修改后的文件（原先已经add/commit过）
git config --global core.editor gedit 设置提交时编辑变更信息的编辑器
git log 查看提交记录
git log --graph --pretty=oneline --abbrev-commit
git show <提交码> 查看某次提交详细的变更信息
git show-branch --more=n 查看简洁的单行提交信息
git diff <提交码> <提交码> 查看两个提交之间的差异
git rm <文件名> 删除文件 （需要进一步git commit）
git rm -r <文件夹> 删除文件夹（需要进一步git commit）
git mv <source文件> <Target文件> 重命名
git clone 创建版本库的符本
git config –l 列出配置
git config –unset 移除设置
git reset ––hard 将版本库和工作目录改变为已知状态
git rev-parse <提交> 查看提交标识

2.2 检出

git checkout HEAD – <文件> 恢复文件的旧版本
git checkout HEAD – <文件夹>恢复文件的旧版本
git checkout <分支名> 检出分支并切换到分支

gitk 版本库的可视化

2.3 分支

git branch 列出分支名
git show-branch 显示分支
git branch <分支> <提交> 创建一个分支，弱不包含提交，则标识从当前分支的HEAD创建一个新的分支
git checkout <分支名> 检出分支
git checkout –b <分支名> 检出新分支，并切换到分支
git branch –d <分支名> 删除分支

2.4 diff

git diff 比较工作目录和索引之间的差异
git diff 显示工作目录和给定提交间的差异
git diff 比较两个提交的差异
git diff --cached 显示索引中的变更和给定提交的变更间的差异

2.5 合并

git merge <分支名> 合并分支

2.6 更改提交

git reset --hard HEAD 把工作目录和索引都还原到git merge命令之前
git reset --hard ORIG_HEAD 若合并并提交后想放弃，则需要使用这条命令进行还原到合并前。Git把原始分支的HEAD 保存在ORIG_HEAD
git reset --soft 将HEAD引用指向给定提交。索引和工作目录的内容保持不变。
git reset --mixed 将HEAD指向给定提交，索引内容也跟着改变以符合给定提交的树结构，但是工作目录中的内容保持不变
git reset --hard将HEAD引用指向给定提交，索引的内容也跟着改变以扶额和给定提交的树结构，工作目录的内容也随之改变以反映给定提交表示的树的状态。
git reset HEAD <文件> 撤回暂存

git reset --mixed HEAD^ 退回上一次提交

git cherry-pick <提交> 在当前分支上应用 给定提交引入的变更。一般合并其他分支上的特定版本的一次变更（如修复某个bug）
git revert <提交> 引入一个新提交来抵消给定提交的影响。常见用途为：如某个提交有缺陷，用来撤销那次提交的变更内容，从而去除那次变更引入的问题。
