How to check which files have been modified in git

In the process of using Git for version control, sometimes we need to check which files have been modified and what content has been modified, so that problems can be discovered and repaired in time. This article will introduce how to check which files have been modified through Git.

1. View modified files

We can view modified files through the git status command. After running this command, Git will list which files have been modified. If the file has been modified but has not been submitted, it will appear in the "Changes not staged for commit" column. If it has been submitted, it will appear in "Changes to be committed".

The specific usage is as follows:

$ git status

2. View the modification details of the file

To view the modification details of the file, we can use the git diff command . This command can list the differences between the two versions, including modification, addition, deletion and other operations. We can specify the file name or folder name to view the corresponding differences. If no file name or folder name is specified, the default is to view the differences of all modified files.

The specific usage is as follows:

# 查看某个文件的修改详情
$ git diff filename

# 查看某个目录下所有文件的修改详情
$ git diff directoryname/

# 查看指定版本之间的差异，例如查看上一次提交和当前工作区之间的差异
$ git diff HEAD

3. View file modification history

We can use the git log command to view a file in the Git warehouse Historical versions, including which versions modified this file, and the specific content of each modification.

The specific usage is as follows:

# 查看某个文件的修改历史
$ git log --follow filename

Through the above command, you can view all modification history of a file, including who modified the file, modification time, submission information, and the difference in file content before and after modification. and other information.
