A brief analysis of how to modify files and submit them in git

When developing software, version control is very important. Git is a popular version control system. It is very simple and easy to use and is favored by many developers. In Git, file modification is a very basic operation. This article will introduce how to modify files with git and submit them.

1. Create a Git repository

If you don’t have a Git repository yet, you need to install Git on the machine, and then use the git init command to create a new repository locally.

$ git init

This command will create a hidden directory named .git in the current directory, which contains all the files and information required by Git. At this point, the Git repository has been successfully created.

2. Edit the file

Next, create a new file in the root directory of the git repository, for example:

$ touch test.txt

Then, use the editor to open the test.txt file , add some text content to it. In this example, we add the following text to test.txt:

学习 Git 是一个很好的选择。

3. Temporary file

After you complete the modification of the file, you need to add the file to the Git temporary area. That is, use the git add command.

$ git add test.txt

At this time, Git adds it to the staging area of ​​the current branch, waiting for you to execute the commit command.

4. Submit changes

Use the git commit command to submit your changes to the Git repository in this step.

$ git commit -m "添加文本 '学习 Git 是一个很好的选择。'"

Please note that you need to add a brief comment to this commit. This comment is intended to summarize this commit and help you better track your Git history later.

After submission, you have submitted the modified contents of the test.txt file to the Git repository.

5. Modify the file and submit it again

To demonstrate how to modify the file and submit it again, the test.txt file will be edited again.

学习 Git 是非常重要的选择。

Use the git add command to add the changes to the staging area.

$ git add test.txt

Use the git commit command to commit the changes to the Git repository.

$ git commit -m "更新文本 '学习 Git 是非常重要的选择。'"

At this point, you have successfully submitted the modifications to the test.txt file to the Git repository.

6. View the commit history

You can view the commit history of the Git repository by running the git log command.

$ git log

This command will list all commit records and display each commit's SHA-1 identifier, commit author, commit date, and commit description.
