🛠️ Version Control Series – Part 2: Essential Git Commands You Should Know Link to heading

In Part 1, we covered why Git is crucial for bioinformatics. Now, let’s dive into the practical side: mastering the core Git commands. Whether you’re starting a new project or collaborating with a team, these commands form the foundation of version control.

🌟 Getting Started: The Basics Link to heading

✅ Initialize a Repository Link to heading

Start tracking changes in your project directory by creating a Git repository:

git init

This sets up a .git folder in your directory to track changes.\

This sets up a .git folder in your directory to track changes.

✅ Add Files to the Staging Area Link to heading

Stage files to include them in the next commit:

git add filename      # Add a specific file
git add .             # Add all files in the current directory`

🔥 Why? This allows you to choose which changes to include in a commit.

✅ Commit Changes Link to heading

Save your changes to the repository:

git commit -m "Your commit message here"

🔥 Pro Tip: Write meaningful commit messages like:
"Added feature X to improve analysis pipeline"

🌟 Working with Remote Repositories Link to heading

✅ Connect to a Remote Repository Link to heading

Link your local repository to a remote one (e.g., GitHub):

git remote add origin https://github.com/username/repository.git

✅ Push Changes Link to heading

Send your local commits to the remote repository:

git push -u origin main

🔥 Why? This shares your work with collaborators or backs it up online.

✅ Pull Updates Link to heading

Retrieve the latest changes from the remote repository:

✅ Clone a Repository Link to heading

Copy an existing repository to your local machine:

git clone https://github.com/username/repository.git

✅ Resolve Merge Conflicts Link to heading

Conflicts occur when multiple changes affect the same line of a file. Git will prompt you to resolve them:

git merge branch-name

Open the conflicting file, resolve the issue, and stage the file:

git add filename git commit -m "Resolved merge conflict in filename"
