Initializing a New Repository
Using git init Command
Every repository starts with git init
. This command takes your current working directory and initializes it as a new repository. It doesn’t touch any existing files in the directory but does create a hidden .git
directory that contains all the metadata related to the new repo necessary for tracking changes.
To convert a local folder into a repository:
- Open the terminal in the directory you’d like to convert.
- Run the command:
git init
A
.git
folder is created in your directory. This folder contains Git records and configuration files. You should not edit these files directly. - Add the path to your remote repository so Git can upload your files into the correct project.
Cloning an Existing Repository with git clone
To start working locally on an existing remote repository, clone it with the command git clone <repository path>
. You can either clone it via HTTPS or SSH, according to your preferred authentication method.
You can find both paths (HTTPS and SSH) by navigating to your project’s landing page and clicking Clone. GitLab prompts you with both paths, from which you can copy and paste in your command line. You can also clone and open directly in Visual Studio Code.
Setting Up Remote Repositories
By adding a remote repository to your local directory, you tell Git that the path to that specific project in GitLab corresponds to that specific folder you have on your computer. This way, your local folder is identified by Git as the local content for that specific remote project.
To add a remote repository to your local copy:
- In GitLab, create a new project to hold your files.
- In your terminal, navigate to your local project directory.
- Add the remote repository with the command:
git remote add origin <remote repository URL>
- Verify the new remote URL with:
git remote -v
Pro Tip: Using GitLab Ultimate, you can leverage advanced features like code quality checks and security scans directly integrated into your workflow.
Staging and Committing Changes
Adding Files to Staging Area with git add
To stage a file for commit, use the command:
git add <file-name OR folder-name>
Repeat this step for each file or folder you want to add. Alternatively, to stage all files in the current directory and subdirectory, type:
git add .
Confirm that the files have been added to staging by using:
git status
The files should be displayed in green text.
Committing Changes with git commit
Once you have files staged, the final step in your workflow is to commit those files to the repository using:
git commit -m "COMMENT TO DESCRIBE THE INTENTION OF THE COMMIT"
Committing is a snapshot of your work, a point in time when changes were made to the repo. This makes it easy to track what changes over time and revert changes if necessary.
Writing Effective Commit Messages
Writing effective commit messages is crucial for maintaining a clear project history. Here are some tips:
- Be concise but descriptive: Summarize the changes in a few words.
- Use the imperative mood: For example, "Fix bug" instead of "Fixed bug".
- Include relevant issue numbers: If your commit addresses a specific issue, reference it in the message.
A well-written commit message can save time during code reviews and when tracking down bugs.
Branching and Merging
Branching and merging are fundamental to managing and integrating different lines of development within a Git repository. Branching allows individual developers or teams to work on features or fixes in isolation, without affecting the main codebase. When it’s time to integrate these changes, merging brings the divergent branches together.
To ensure a smooth merging process, it’s essential to understand the different merge strategies available:
Working with Remote Repositories
Working with remote repositories is a fundamental aspect of using Git in a collaborative environment. Understanding remote branches is crucial; they are versions of your branches in a remote repository, such as GitHub or GitLab, allowing multiple developers to contribute to the same project. To synchronize your work with the team, familiarize yourself with the following commands:
Utilizing Advanced Git Commands
When you’re comfortable with basic Git commands, you’re ready to dive into the more complex features of Git. These commands aren’t required when creating straightforward changes. When you begin managing multiple branches or need more complex change management, you’re ready for these features:
