A brief analysis of how to submit modified files in git

Git is a distributed version control system that is widely used in software development. In Git, modifying files usually requires multiple steps such as adding and submitting. This article will introduce in detail how to submit modified files to facilitate developers to use Git for version control.

1. Check modified files

In Git, modifying files needs to be done by editing source code or text files. Before submitting, you need to check the modified file to confirm whether the modified content is correct. You can use the following command to view file modifications:

git status

This command will list all modified files in the current warehouse and indicate the status of each file. Usually, the status of modified files is as follows:

• Not modified: The file has not been modified in any way and is the same as the latest version.
• Modified: The file has been modified but has not yet been submitted to the repository.
• Staged (staged): The file has been added to the Git staging area, but has not yet been submitted to the repository.
• Untracked: The file has not yet been included in version control.

After confirming the status of the modified file, you can choose to add the file to the Git staging area for submission.

2. Add modified files

Use the following command to add the modified files to the Git staging area:

git add <filename>

Among them, < filename> is to modify the file name of the file. You can use the wildcard character * to add multiple files. For example, to add all modified files in the directory to the staging area:

git add .

3. Submit modified files

When all modified files have been added to the staging area , you can use the following command to submit the file to the repository:

git commit -m '<commit message>'

Among them, <commit message> is the comment information of this submission, which is used to describe the purpose of this submission. and content. Annotation information should be as concise and clear as possible so that others can understand it. For example:

git commit -m 'Add new feature for login system'

4. Push modified files

When all modified files have been submitted to the repository, you can use the following command to push the local modifications to the Git upstream server:

git push <remote> <branch>

Among them, <remote> is the name or address of the Git upstream server, usually origin. <branch> is the local branch name, and the default is master. For example:

git push origin master

5. Undo modified files

When you find that there are errors in the modified files that have been submitted or you need to undo the modifications, you can use the following command to undo:

• Undo the modification of the staged file and return to the unstaged state:

git reset <filename>

• Undo the modification of the unstaged file and return to the state of the last submission:

git checkout <filename>

• Undo the modification of the submitted file and return to the state of the last submission:

git revert <commit-hash>

Among them, <commit-hash> is the hash value of the submission to be revoked.

Summary

This article introduces how to submit modified files to the Git repository, including operations such as checking files, adding files, submitting files, pushing files, and undoing modifications. Using Git for version control can make multi-person collaborative development more convenient and efficient. I hope that through the introduction of this article, everyone can improve their Git skills and bring more convenience to development work.
