In this part of our journey into Git, we will look at some practical tasks to help us understand the basics of Git and GitHub. These tasks will give us hands-on experience with essential Git commands, from setting up a local repository to pushing changes to a remote repository on GitHub. Upon completing this guide, we will have a strong foundation to build upon as we progress to more advanced Git topics.

Tasks

Local Repository Setup

A local repository is where the project begins. It is a directory on the computer where Git tracks all changes. Here is how to set up a local repository:

  1. Set the username and email address:
    This information will be associated with every commit we make.
bash 
git config --global user.name "git-adrianrubico"
git config --global user.email "adrianrubico@icloud.com"
  1. Create a directory:
    Choose a location on the computer and create a new directory for our project.
bash 
mkdir 90DaysDevOpsChallenge
cd 90DaysDevOpsChallenge
  1. Initialize the directory with Git:
    Turn your directory into a Git repository.
bash 
git init
  1. Create a README.md file:
    Add a README.md file to describe your project.
bash 
echo "#90DaysDevOpsChallenge" > README.md

Setup Remote Repository

The remote repository is a platform like GitHub where you can share, collaborate, and manage your code. Follow these steps to set up your remote repository:

  1. Create Github Account:
    If you haven't already, go to Github and create an account.
  2. Create a new repository on Github:
    Name it 90DaysDevOpsChallenge.

Integrate Local Repository to Remote Repository

Now, let's connect local repository with our Github repository:

  1. Add the remote repository:
    Link your local repository to the remote one on Github.
bash 
git remote add origin https://github.com/git-adrianrubico/90DaysDevOpsChallenge.git
  1. Commit your changes:
    Stage and commit your files.
bash 
git add .
git commit -m "Initial commit"
  1. Push to Github:
    Send your changes to the remote repository.
bash 
git push origin master

💡 You may change the name of your default branch in the these following process "Go to your repository" ➡️ "Settings" tab ➡️ "Default branch" section.

Create a New File and Add Some Contents

Now, let's create a new file, add some content, and push it to Github:

  1. Create a new file:
    For example, create a file named example.txt.
bash 
echo "This is an example text." > example.txt
  1. Check the status:
    See which files have changed and are ready to be committed.
bash 
git status
  1. Stage and commit your new file:
    Add the file to the staging area and commit it.
bash 
git add example.txt
git commit -m "Add example.txt"
  1. Push the file to Github:
    Send the changes to the remote repository.
bash 
git push

Navigate the Git Logs

The Git log is a powerful tool for seeing the history of your commits. Here's how to use it:

  1. View the commit history:
bash 
git log

💡 You can also use flags like --oneline for a more concise view

Wrapping Up

Our blog covered the essential steps to get started with Git and GitHub, from setting up a local repository to pushing your first file to a remote repository. These foundational skills will prove essential as you explore Git in future tasks. Our next blog will focus on rolling back changes in Git, an important tool for managing your code.
