在本文章教程中，我们将演示如何查看 Git 存储库的文件和提交文件记录，并对存储库中的文件作修改和提交。
在上一步中，我们已经修改了 main.py 文件中的代码，在代码中定义了两个变量并提交代码，但是要再次添加和修改main.py 文件中的代码，实现新功能：求两个变量相加值。修改提交的操作更改包含提交消息的最后一个提交; 它创建一个新的提交ID。
在修改操作之前，检查提交日志，如下命令所示：
$ git log commit d757c8e92ad6053db294100c77075865f829b7ac Author: your_name Date: Fri Jul 7 23:04:16 2017 +0800 define two var a & b commit be24e214620fa072efa877e1967571731c465884 Author: your_name Date: Fri Jul 7 18:58:16 2017 +0800 ？？mark commit 5eccf92e28eae94ec5fce7c687f6f92bf32a6a8d Author: your_name Date: Fri Jul 7 18:52:06 2017 +0800 this is main.py file commit mark use -m option commit 6e5f31067466795c522b01692871f202c26ff948 Author: your_name Date: Fri Jul 7 18:42:43 2017 +0800 this is main.py file commit mark without use "-m" option commit 290342c270bc90f861ccc3d83afa920169e3b07e Author: Maxsu <769728683@qq.com> Date: Fri Jul 7 16:55:12 2017 +0800 Initial commit
下面我们打开文件：main.py 加入以下两行：
c = a + b
print("The value of c is ", c)更正操作提交新的更改，并查看提交日志。首先查看状态，如下命令：
$ git status On branch master Your branch is ahead of 'origin/master' by 4 commits. (use "git push" to publish your local commits) Changes not staged for commit: (use "git add ..." to update what will be committed) (use "git checkout -- ..." to discard changes in working directory) modified: main.py no changes added to commit (use "git add" and/or "git commit -a")
添加文件并查看状态，如下命令：
$ git add main.py Administrator@MY-PC /D/worksp/sample (master) $ git status On branch master Your branch is ahead of 'origin/master' by 4 commits. (use "git push" to publish your local commits) Changes to be committed: (use "git reset HEAD ..." to unstage) modified: main.py
提交更改的文件，如下所示：
$ git commit --amend -m "add the sum of a & b " [master 51de0f0] add the sum of a & b 1 file changed, 5 insertions(+), 1 deletion(-)
现在，使用 git log命令显示将显示新的提交消息与新的提交ID(51de0f02eb48ed6b84a732512f230028d866b1ea)，最近一次提交的放前面：
$ git log commit 51de0f02eb48ed6b84a732512f230028d866b1ea Author: your_name Date: Fri Jul 7 23:04:16 2017 +0800 add the sum of a & b commit be24e214620fa072efa877e1967571731c465884 Author: your_name Date: Fri Jul 7 18:58:16 2017 +0800 ？？mark commit 5eccf92e28eae94ec5fce7c687f6f92bf32a6a8d Author: your_name Date: Fri Jul 7 18:52:06 2017 +0800 this is main.py file commit mark use -m option commit 6e5f31067466795c522b01692871f202c26ff948 Author: your_name Date: Fri Jul 7 18:42:43 2017 +0800 this is main.py file commit mark without use "-m" option commit 290342c270bc90f861ccc3d83afa920169e3b07e Author: Maxsu <769728683@qq.com> Date: Fri Jul 7 16:55:12 2017 +0800 Initial commit
