Today, we'll start with the `git init` command. Can anyone tell me what it does?
It starts a new Git repository, right?
That's correct! When you run `git init`, it creates all the necessary files that Git uses to track changes in that directory. You can think of it as setting up a new storage box for your project.
So, it's like getting a new notebook for coding?
Exactly! A great analogy. Remember, when using `git init`, you want to be in the right directory. Any questions?
Checking Status with git status

Next, let's talk about `git status`. Who can explain its purpose?
It shows the status of files in the repository.
Correct! `git status` tells you which files are staged for commit, which are modified but not staged, and which are untracked. It's crucial for understanding your current workspace.
Can I use it anytime?
Absolutely! You can use `git status` any time to check your progress. It's a good habit to get into.
Staging Changes with git add

Now, onto `git add`. Who wants to give a brief explanation?
It stages a file for commit!
Exactly! By using `git add <filename>`, you prepare files to be saved into version history. It's the first step in tracking changes. Why do you think staging is important?
Because you can choose which changes to commit and which to leave out?
Yes! It gives you control over what gets committed. Excellent point!
Committing Changes with git commit

Next, let's dive into `git commit`. Can someone explain how it works?
It saves the staged changes to the repository with a message!
Right! When you run `git commit -m 'message'`, it's like taking a snapshot of your work. Why is the commit message important?
It helps others understand what changes were made!
Exactly! Good commit messages help you look back and understand the project's evolution.
Pushing Changes to GitHub

Finally, let's discuss how to push changes to GitHub with `git push`. Why do we do this?
So that our code is saved online and can be shared with others!
Exactly! After linking with `git remote add origin URL`, you can use `git push -u origin main` to upload your files. It's like sending your completed project to your instructor!
And we can collaborate on it afterward?
Absolutely! That's the power of Git and GitHub working together.

Summary of Common Git Commands
In this section, we will explore the most commonly used Git commands that every user should know to manage their coding projects efficiently. This list includes commands for initializing repositories, checking file statuses, staging changes, committing updates, viewing history, and linking local repositories with GitHub.
- git init: Starts a new Git repository. This command sets up a new version control system in the directory you are currently in.
- git status: This command allows you to see the current status of your files in the repository, indicating which files are staged, unstaged, or untracked.
- git add filename: Use this command to stage changes in a specific file, making it ready for committing.
- git commit -m 'message': This command saves your staged changes into the version history with a descriptive message. This message is vital in tracking the history of your project.
- git log: Allows you to view your commit history, providing insights into what changes have been made, when, and by whom.
- git remote add origin URL: Links your local Git repository to a remote repository (like GitHub), enabling you to push your changes online.
- git push: This command uploads your local changes to the remote repository on GitHub, making your updates accessible to others.

git init Start a new Git repo
Detailed Explanation
The command git init is used to create a new Git repository. This sets up the necessary files and structure that Git needs to track changes in your code.
Examples & Analogies
Think of it like opening a new notebook to start a new project. Just like you would need a blank notebook before you can begin taking notes, you need to run git init to create a new Git environment for your code.
Checking File Status

git status Check file status
Detailed Explanation
The git status command allows you to see the current state of your working directory and staging area. It shows which files are staged for the next commit, which are modified, and which are untracked.
Examples & Analogies
Imagine checking your shopping list before heading to the store. You want to ensure everything you need is either in your cart or noted down. Similarly, git status lets you see what files are ready to be saved and what changes are still pending.
Staging Changes

git add filename Stage changes
Detailed Explanation
The command git add filename is used to stage changes in your files before committing them. This means you are preparing the updated files to be saved permanently in the Git history.
Examples & Analogies
It’s like preparing your documents for submission. Before you submit, you gather all the final drafts and place them in a folder (staging). Only when you are completely ready do you submit the folder for review.
Saving Snapshots of Changes

git commit -m 'message' Save snapshot
Detailed Explanation
The command git commit -m 'message' saves your staged changes into the Git history. The message you provide should summarize what changes were made, making it easier to remember in the future.
Examples & Analogies
Think of this as taking a snapshot with a camera. When you take a picture, you capture that moment in time. Similarly, a commit saves a 'snapshot' of your code at that point, along with a note describing what's included in that snapshot.
Viewing Commit History

git log View commit history
Detailed Explanation
The git log command displays a list of all your past commits, showing details such as commit ID, author, date, and the commit message. This allows you to look back at the project's development and understand its history.
Examples & Analogies
Imagine looking through an album of family photos. Each photo represents a moment in time with details about where you were and what you were doing. git log gives you a similar timeline for your code, letting you see how it has changed over time.
Connecting to GitHub

git remote add origin Link to GitHub URL
Detailed Explanation
The command git remote add origin URL is used to link your local repository with a remote repository on GitHub. This connection enables you to push your local commits to the online repository.
Examples & Analogies
Think of this as establishing a connection between your laptop (local repository) and a cloud storage service (GitHub). By creating this link, you can back up your important documents to the cloud and access them from anywhere.
Uploading Your Code

git push Upload to GitHub
Detailed Explanation
Finally, the git push command is used to upload your local changes to the remote repository on GitHub. This ensures that your online repository is updated with the latest commit from your local machine.
Examples & Analogies
It's like mailing a letter. Once you've written your letter (made your changes) and prepared it for sending (committed the changes), hitting git push is like placing the letter in the mailbox for delivery to its destination (your GitHub repository).
