克隆项目
我们除了可以向GitHub上提交项目外，更多的时候是我们到上面克隆（下载）优秀的开源项目来用，当然也可以将使用过程中发现的bug，通过建立分支的方式提交给项目的原作者。 我们现在的场景是在家将项目提交到了GitHub上，现在来到公司，需要将GitHub上的项目克隆到本地，那么对于公司的电脑来说，同样需要与GitHub建立连接。
首先，下载安装Git。
其次，通过Git生成本地公钥，并且将公钥添加到GitHub中。
最后，设置仓库人员的用户名和邮箱地址。
具体操作请参考前面的章节。当一切都设置完成后，就可以从GitHub上克隆项目到本地了。我们同样以Windows系统为例，打开Git Bash。
Company@MININT-IQVJFIT /d/my_test $ git clone git@github.com:defnngj/project-name.git Cloning into 'project-name'... remote: Counting objects: 3, done. remote: Compressing objects: 100% (2/2), done. remote: Total 3 (delta 0), reused 3 (delta 0), pack-reused 0 Receiving objects: 100% (3/3), done. Checking connectivity... done. Company@MININT-IQVJFIT /d/my_test $ cd project-name/ Company@MININT-IQVJFIT /d/my_test/project-name (master) $ ls test_case.py
“git clone” 命令用于克隆GitHub上的项目到本地。通过“cd”命令进入项目目录，查看项目文件。
另外，我们也可以直接通过http链接克隆项目：git clone https://github.com/defnngj/project-name
$ git clone https://github.com/defnngj/project-name
更新项目
这次更新我们项目做了较大的变更，创建文件的文件与文件夹，并且删除了原有文件。
Company@MININT-IQVJFIT /d/my_test/project-name (master) $ git status On branch master Your branch is up-to-date with 'origin/master'. Changes not staged for commit: (use "git add/rm <file>..." to update what will be committed) (use "git checkout -- <file>..." to discard changes in working directory) deleted: test_case.py Untracked files: (use "git add <file>..." to include in what will be committed) 126login.py baidu.py package/ po_login.py test_case/ no changes added to commit (use "git add" and/or "git commit -a")
通过“git status” 命令查看当前变更。通过变更信息可以看出，删除了test_case.py文件。这个删除只是在项目目录下进行删除，Git对此文件留有记忆，所以要通过 “git rm” 命令将其删除。
Company@MININT-IQVJFIT /d/my_test/project-name (master) $ git rm test_case.py rm 'test_case.py'
如果删除的是文件同样用此命令，例如，git rm test_case/。
如果删除的文件名带空格，则需要通过双引号将文件名引起来，例如，git rm “test case.py”。
Company@MININT-IQVJFIT /d/my_test/project-name (master) $ git add . Meizu@MININT-IQVJFIT /d/my_test/project-name (master) $ git status On branch master Your branch is up-to-date with 'origin/master'.

“git add” 命令对当前目录下的文件添加跟踪。
“git commit” 命令将添加文件提交到本地仓库。
“git push” 将本地项目提交到远程仓库GitHub。
注：除第一次下载项目需要通过 “git clone” 将项目克隆到本地外,后续再使用 “git pull” 命令时会直接将更新拉取到本地。

提示: 为了避免冲突我们应该形成良好的习惯，在每次 push 代码之前先把服务器上最新的代码 pull 到本地。
