IQCode's 2023 Guide to GIT Cheat Sheet

Introduction: Understanding Git

Git is a powerful and popular distributed version control system that is available for free and open-source use. It is designed to handle projects of varying sizes with speed and efficiency.

Why Use Git? Benefits Explained

Imagine a scenario in which a large project has 100 developers working on it. Prior to Git:

- Developers submitted their codes to the central server without having a copy of their own. - Changes made to the source code were not known to other developers. - There was no communication amongst the developers.

Now, let's analyze the same scenario post Git:

- Every developer has a copy of the code on their local system. - Changes made to the source code can be tracked by others. - There is regular communication between the developers.

Therefore, for large projects that involve a myriad of developers, Git fosters efficient and structured collaboration.

Learn Git: From the Basics to Advanced Concepts

1. Exploring the Uses of Git

Installing Git on Windows, Linux, and macOS

Code:

To install Git on Windows, Linux, or macOS, follow the instructions below:

Windows:

1. Download the Git installer from the official Git website: https://git-scm.com/download/win
2. Run the installer and follow the prompts, keeping the defaults unless you have a specific preference.
3. Once the installation is complete, open the command prompt and run the command:

   git --version

   . If Git is installed correctly, it will display the version number.

Linux:

1. Open your terminal and run the following command to install Git:
   

   sudo apt-get install git-all

2. Verify that the Git installation was successful by running the command:

   git --version

   . If Git is installed correctly, it will display the version number.

macOS:

1. Download the Git installer for macOS from the official Git website: https://git-scm.com/download/mac
2. Double-click the downloaded file to start the installation process and follow the prompts, keeping the defaults unless you have a specific preference.
3. Once the installation is complete, open the Terminal application and run the command:

   git --version

   . If Git is installed correctly, it will display the version number.

Creating Remote Branches

In version control systems like Git, a branch is a pointer to a snapshot of a repository's files. Creating and managing branches is a fundamental aspect of Git workflows.

To create a new remote branch in Git, you can use the following command:

git push <remote-name> <local-branch-name>:<remote-branch-name>

Here, `remote-name` is the name of the remote repository, `local-branch-name` is the name of the local branch, and `remote-branch-name` is the name of the remote branch that you want to create.

For example, if you want to create a new branch called "new-feature" on the remote repository "origin" that is based on your current local branch "main," you can use the following command:

git push origin main:new-feature

This will create a new branch called "new-feature" on the remote repository "origin" that is identical to your local "main" branch.

It's important to note that before creating a new remote branch, you should first ensure that your local branch is up-to-date with the remote repository's latest changes. You can do this by running `git fetch ` to fetch the latest changes from the remote repository and then merging them into your local branch.

By creating remote branches, you can collaborate with other developers and work on multiple features or fixes simultaneously without affecting the development of the main branch.

How to Pull Remote Branch using Git

To pull changes made in a remote branch in Git, you can use the following command:

git pull [remote_name] [remote_branch_name]

For example, if the remote branch is called "feature-branch" and the remote repository is named "origin", you can use the following command:

git pull origin feature-branch

This will pull the latest changes from the remote branch and merge them with your local branch. If there are any conflicts, you will need to resolve them manually before committing the changes.
