git creates non-existent branch

In recent years, git has become an indispensable version control tool in developers' work, but there are also some difficulties in git operations, such as how to create non-existent branches. This article will explain in detail how to create a non-existent branch in git. I hope it will be helpful to you.

Introduction to Git Branches

Before you start learning how to create a non-existent branch, you first need to understand the concept of branches in git. A branch is a pointer to a commit object in the git commit history. The submission object contains the change content of the file and the metadata describing the submission content. When we create a branch in git, the object pointed to by the branch is the submission object of the previous object of the original branch.

List all git branches

In git, we can view existing branches through git branch. The command to list all branches is as follows:

$ git branch

Among them, the branch with an asterisk indicates the current branch.

Create a new branch

If you want to create a new branch, you can use the following command:

$ git branch <branch-name>

This will create a new branch named eb499bedd9f9993b7d4c66fdbb1b020f branch, but the branch has not been checked out, so the file cannot be modified. If you want to check out this branch, you can use the following command:

$ git checkout <branch-name>

Now, you can modify the files under this branch.

How to create a branch that does not exist

What should you do if you want to create a branch that does not exist? In fact, git is very simple. We only need to specify a non-existent branch name after the git branch command, for example:

$ git branch my-new-branch

At this time, git will create a branch in your local warehouse A branch named " my-new-branch ".

Switch to the branch immediately after creating the branch

If you want to switch to the branch immediately after creating the branch, you can use the following command:

$ git checkout -b my-new-branch

This command cannot be used alone use. It creates a new branch and points the HEAD pointer to that branch. In our subsequent work, we will modify files and other operations on this new branch.

Branch naming convention

When using git to create a new branch, we should follow some naming conventions to facilitate subsequent use.

• The branch name is prefixed with feature/fix/hotfix, which indicates a branch with new features, bug fixes or hot fixes.
• Branch names use lowercase letters, and words are separated by dashes "-".
• The branch name adopts concise naming, which is helpful for subsequent clear naming management.

Conclusion

In this article, we explain in detail how to create non-existent branches in git and give the specifications for branch naming. I hope that through this article, you can better master git operations, improve development efficiency, and better manage branches in team collaboration.
