Detailed explanation of how git pulls branches

With the development of software development, version control has become a vital part of the modern development process. Git is one of the most popular version control management tools currently. Git can not only store history, but also develop multiple feature branches in parallel and eventually merge them together. In Git, branches are an indispensable part. This article will focus on how to pull branches.

1. Introduction to Git branches

In Git, "branch" actually refers to some pointers pointing to specific commits (commits). Git has a branch named master by default, which is the main branch. When you first enter a Git repository and start working, the master branch will be the branch you are on.

Branch can be seen as a key element in the Git workflow. Through branches, we can isolate the main code development work from other work, and then conduct different attempts and experiments on other branches. For example, during development, we need to create a "development branch". At this time, development can be carried out on the branch without affecting other branches.

2. Git branch command

2.1 Branch creation

To create a new branch in Git, we need to use the git branch command, which needs to be specified later. branch name. For example, if we want to create a new branch named "develop", we can enter the following command:

git branch develop

2.2 Branch switching

Use the git checkout command to switch branches. In ordinary development operations, it may be necessary to switch between different branches frequently. To achieve this purpose, Git uses the "checkout" command to support branch switching. For example, if we want to switch to the branch named "develop", we can enter the following command:

git checkout develop

2.3 Branch Merge

To merge the branch into another branch created on its basis On a branch, we need to use the git merge command, which is followed by the name of the branch that needs to be merged. For example, if we want to merge the develop branch into the master branch, we can enter the following command:

git checkout master
git merge develop

2.4 Branch deletion

If we no longer need a branch, we can use git The branch -d command deletes it. After this command, you need to specify the name of the branch to be deleted. For example, if we want to delete the branch named "develop", we can enter the following command:

git branch -d develop

3. Git pull branch

When doing team development, you may need to pull branches from other developers The person pulls a copy of the code they need from the remote branch. The following are the steps to pull a branch:

3.1 View the remote branch list

Before pulling the remote branch, we need to use the "git branch -r" command to view the remote branches we can pull. list. For example:

git branch -r

3.2 Local branch pulls remote branch

You can use the "git checkout -b local branch name origin/remote branch name" command to pull the remote branch to the local branch. For example:

git checkout -b develop origin/develop

This command will create the local branch "develop", which is used to track the remote branch "origin/develop".

3.3 Pull the branch and switch

If you want to pull the remote branch and switch it to the branch immediately, you can use the following command:

git checkout -t origin/develop

This command will Create a local branch with the same name as the remote branch for tracking purposes.

4. Summary

Git is an extremely powerful version control system that supports multiple operation methods. In this article, we introduced Git’s branch operations. We can create, merge, and delete branches as needed. At the same time, we also learned how to pull remote branches and connect them with the tracking of the local branch. Mastering these skills will help us better understand and use Git, thereby improving our development efficiency and code management capabilities.
