Repository Setup

This repository is a step-by-step guide to setting up a new Git repository, creating and modifying files, committing changes, creating and merging branches, and pushing the changes to a remote repository on GitHub.

Prerequisites

Before you begin, you'll need to have the following installed on your system:

- Git (https://git-scm.com/downloads)
- A text editor or an IDE of your choice
- A GitHub account (https://github.com)

Getting Started

1. Configure Git User Name and Email (if needed)

Before running the git push command, you may need to configure your Git user name and email address using the following commands:

git config --global user.name "Your Name"

git config --global user.email "[email protected]"

Replace "Your Name" and "[email protected]" with your actual name and email address.

2. Create a New Repository on https://github.com

macOS

Create a new directory for the project (Locally in terminal)

mkdir software_design

cd software_design

Initialize a new Git repository

git init

Create a new remote repository on GitHub

(Open your web browser, navigate to GitHub, and create a new repository named "software_design")

Copy the URL of the new repository (e.g., https://github.com/your_username/software_design.git)

Connect the local repository to the remote repository

git remote add origin https://github.com/your_username/software_design.git

Windows

Create a new directory for the project (Locally in terminal)

mkdir software_design

cd software_design

Initialize a new Git repository

git init

Create a new remote repository on GitHub

(Open your web browser, navigate to GitHub, and create a new repository named "software_design") Copy the URL of the new repository (e.g., https://github.com/your_username/software_design.git)

Connect the local repository to the remote repository

git remote add origin https://github.com/your_username/software_design.git

3. Create and Upload File

macOS

Create a file named index.txt in your local repository

printf "Hello, GitHub!" > index.txt

Add the file to the staging area

git add index.txt

Commit the file with the message "First Commit"

git commit -m "First Commit"

Push the changes to the remote repository

git push -u origin master

OR

git push -u origin main

Windows

Create a file named index.txt in your local repository

echo "Hello, GitHub!" > index.txt

Add the file to the staging area

git add index.txt

Commit the file with the message "First Commit"

git commit -m "First Commit"

Push the changes to the remote repository

git push -u origin master

OR

git push -u origin main

4. Make Changes and Commits

Follow the same pattern for both macOS and Windows:

# Change 1
For windows: echo "Test written 1" > index.txt
For macOS: printf "Test written 1" > index.txt
git add index.txt
git commit -m "Second Commit"
git push

# Change 2
For windows: echo "Test written 2" > index.txt
For macOS: printf "Test written 2" > index.txt
git add index.txt
git commit -m "Third Commit"
git push

# Change 3
For windows: echo "Test written 3" > index.txt
For macOS: printf "Test written 3" > index.txt
git add index.txt
git commit -m "Fourth Commit"
git push

# Change 4
For windows: echo "Test written 4" > index.txt
For macOS: printf "Test written 4" > index.txt
git add index.txt
git commit -m "Fifth Commit"
git push

# Change 5
For windows: echo "Test written 5" > index.txt
For macOS: printf "Test written 5" > index.txt
git add index.txt
git commit -m "Sixth Commit"
git push

5. Create and Merge Branch

Follow the same pattern for both macOS and Windows:

Create a new branch named 'Branch_1' from the main/master branch

git branch Branch_1

Switch to the 'Branch_1' branch

git checkout Branch_1

Modify index.txt in this branch

For Window, use:

echo "New branch test written 1" >> index.txt

For MacOS, use:

printf "New branch test written 1\n" >> index.txt

git add index.txt

git commit -m "Branch First Commit"

git push origin Branch_1

6. Merge Branch and Push Changes

Follow the same pattern for both macOS and Windows:

Switch back to the main/master branch

git checkout master

OR

git checkout main

Merge the changes from 'Branch_1' into the main/master branch

git merge Branch_1

Push the merged changes to the remote repository

git push

That's it! You've successfully set up a new Git repository, created and modified files, committed changes, created and merged branches, and pushed the changes to a remote repository on GitHub.
