在本文章教學中，我們將演示如何檢視 Git 儲存庫的檔案和提交檔案記錄，並對儲存庫中的檔案作修改和提交。
注意：在開始學習本教學之前，先克隆一個儲存庫，有關如何克隆儲存庫，請參考： /6/67/2091.html
在上一步中，我們已經修改了 main.py 檔案中的程式碼，在程式碼中定義了兩個變數並提交程式碼，但是要再次新增和修改main.py 檔案中的程式碼，實現新功能：求兩個變數相加值。修改提交的操作更改包含提交訊息的最後一個提交; 它建立一個新的提交ID。
在修改操作之前，檢查提交紀錄檔，如下命令所示 -
$ git log

Initial commit
下面我們開啟檔案：main.py 加入以下兩行：
c = a + b
print("The value of c is ", c)
更正操作提交新的更改，並檢視提交紀錄檔。首先檢視狀態，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 <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: main.py
no changes added to commit (use "git add" and/or "git commit -a")
新增檔案並檢視狀態，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 <file>..." to unstage)
modified: main.py
提交更改的檔案，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(-)
現在，使用 git log命令顯示將顯示新的提交訊息與新的提交ID(51de0f02eb48ed6b84a732512f230028d866b1ea)，最近一次提交的放前面：
$ git log
