Let's talk about how to use Git and precautions

As an essential version control tool for programmers and developers, Git has become mainstream. However, many people often encounter some problems when using Git, such as not knowing how to use common Git commands, what to do if conflicts occur, and so on. So, this article will introduce to you how to use Git and precautions to help you better master Git.

1. The basic concept of Git

Git is a distributed version control system that can help us manage code versions in the software development process. We submit the code to the Git repository for management, which allows us to easily trace and manage different versions of the code.

The most important thing in Git is the concept of repository. A repository is a Git repository that holds code and other resources. Each repository can contain multiple versions, each representing a different state of the code.

2. Git command

1. git clone: ​​Download the Git repository to the local

In Git, we need to clone the remote code repository to the local first can be developed. Use the git clone command to clone the remote repository to the local one:

git clone [仓库地址]

2. git init: Initialize the Git repository

If you already have a local project, you can use git init Command to initialize it as a Git repository:

git init

3. git add: Add files to the Git repository

Use the git add command to add files to the Git repository:

git add [文件名]

4. git commit: Submit the code to the Git repository

Use the git commit command to submit the code to the Git repository and make the code a new version.

git commit -m "提交信息"

5. git push: push the code to the remote Git repository

Use the git push command to push the code to the remote Git repository:

git push [仓库名称] [分支名称]

6. git pull: Pull code from the remote Git repository

Use the git pull command to pull code from the remote Git repository:

git pull

7. git branch: Display the Git branch List

Use the git branch command to display the Git branch list:

git branch

8. git checkout: switch Git branches

Use the git checkout command to display Switch Git branches:

git checkout [分支名称]

9. git merge: merge Git branches

Use the git merge command to merge Git branches:

git merge [分支名称]

3. Some Git Note

1. Git conflicts

During development, sometimes we will have Git conflicts because the code is not updated in time. When a Git conflict occurs, we need to manually merge the code and then commit it to the Git repository.

2. Git Branch

During the development process, we need to create multiple branches to organize and manage code projects. When creating branches, you need to pay attention to the relationship between multiple branches for better collaboration and merging.

3. Git rollback

During the development process, we may need to roll back the submitted code. Rollback can be achieved using the Git rollback command. When using Git to roll back, you need to pay attention to the rolled back version to avoid causing code confusion.

4. Conclusion

The above are the basic concepts and usage methods of Git. I hope it can help everyone understand Git better. Of course, there are many advanced usage methods of Git that require further learning and mastering. However, as long as we can master the basic usage of Git, we can develop software more efficiently.
