How to use Git from the command line

Git is a powerful version control system, through the command line interface to operate. This guide walks you through the basic steps of using the Git command line, allowing you to manage code changes, track file history, and collaborate on development.

1. Install Git
First, make sure Git is installed on your computer. For most operating systems, you can download and install Git from the official website.

2. Initialize the repository
To start using Git, you first need to create or initialize a Git repository. Open a command prompt or terminal in the project directory you want to track, and then run the following command:

<code>git init</code>

3. Add files
Add the files in the project to the Git repository, to keep track of it. Use the following command:

<code>git add <filename></filename></code>

4. Commit changes
Commit the added files to the local repository to create a history snapshot. Use the following command:

<code>git commit -m "提交信息"</code>

5. Clone the repository
To clone or create a local copy from an existing repository, use the following command:

<code>git clone <repository_url></repository_url></code>

6. Pull changes
Pull new changes from the remote repository to update the local repository. Use the following command:

<code>git pull</code>

7. Push changes
Push local changes to the remote repository to share with others. Use the following command:

<code>git push</code>

8. Branch Management
Create branches to try new features or fix bugs without affecting the main branch. Use the following command:

<code>git branch <branch_name>
git checkout <branch_name></branch_name></branch_name></code>

9. Merge Branches
Merge changes from one branch to another. Use the following command:

<code>git merge <branch_name></branch_name></code>

10. Roll Back Changes
Undo the most recent commit or change to go back to the previous version. Use the following commands:

<code>git reset --hard <commit_hash></commit_hash></code>

By mastering these basic commands, you can effectively use Git to manage your code from the command line.
