How to Switch Branches in Git? - 面试题

Switching branches in Git is straightforward, primarily using the git checkout command. Here are the specific steps and examples:

View existing branches: First, use the git branch command to list all branches in the repository, where the current branch is marked with an asterisk (*).

For example, the command output might appear as:
```
shell
* master
  develop
  feature-x
```
Switch branches: Use the git checkout [branch-name] command to switch to your target branch. Here, [branch-name] represents the name of the branch you want to work on.

For instance, to switch to the develop branch, run:
```
shell
git checkout develop
```
After execution, Git updates the working directory to match the state of the develop branch.
Verify the switch: To confirm the current branch, run git branch again. If successful, the asterisk (*) will now precede the develop branch:
```
shell
  master
* develop
  feature-x
```

Additionally, starting with Git version 2.23, you can use the git switch command for branch switching, which offers a more intuitive approach. The syntax is git switch [branch-name].

For example:

shell
   git switch develop

This method enhances Git usage by making it more intuitive and professional. It clearly separates branch switching from file restoration (previously handled by git checkout), improving workflow clarity.

This covers the fundamental operations and steps for switching branches in Git. We hope this guide helps you better understand and utilize Git for version control.
