If you’re a new programmer, you should learn about version control systems.
The majority of programming jobs will need you to communicate with other engineers using one of these version control systems since it is the best approach to structure huge codebases and reduce the impact of mistakes or inconsistencies. Git is an example of a version control system.
We’ll go through what Git is and how to get it up and running on your Mac in a few simple steps. You’ll also learn a few key commands to help you get started with Git in your workflow as soon as you finish reading this article!
Git Educated: What Is Git and How Does It Help Me?
Git, as previously stated, is an open-source version management system (also known as a version control tool or source control). A version control tool’s principal goal is to monitor the changes that occur in a codebase whenever it is updated and to enable you to rollback to any iteration of your choice.

When you find you’ve created a bug that turns your app’s logic inside out and upside down, this is a huge assistance. In the case of a compiler displaying red error letters, just revert to your previous Git repository and visit Stack Overflow to figure out what went wrong the first time—no harm, no foul.
Git is also free to use.
How to Install Git on a Mac
Git is preloaded on macOS by Apple. Open your preferred Terminal or shell script editor and type git —version to see which version of Git is installed on your computer. If Git is not already installed on your system, running git —version will ask you to do so.
While this Git build may be enough for certain users, you may prefer to install the most recent version (Apple is often slow to update its version). You may achieve this in a variety of ways; we’ve gathered a few of the simplest ones below.

Installing Git on macOS With Homebrew
Make your own homebrew. Homebrew installs a number of helpful packages that aren’t pre-installed on Macs (the list of packages may be found on Homebrew’s website).
To install Homebrew, type the following command into your terminal:
The specified language : bash” does not exist''
Code generation failed!!
The terminal will ask you for a password. Continue the installation by entering the password you use to log in to your Mac.
When you’re done, type brew install git into the terminal and wait for it to download. Run git —version to confirm that Git was installed.
How to Install Git on macOS With the Stand-Alone Installer
Tim Harper created and maintains a standalone installation for Git for Mac, which you can get on SourceForge. Simply click Download to receive the most recent version, or click straight on any prior build under the Project Activity heading to access it.
Run the installer and follow the steps until Git is installed on your PC. Run git —version in the terminal to confirm that Git was installed. You’ve completed your task!
Please be aware that some users have reported compatibility difficulties with the standalone installation and Mac OS X Snow Leopard or Mac OS X Lion (OSX 10.6 and 10.7). While there are solutions, we highly advocate installing Git using Homebrew to prevent problems.
Installing Git for macOS With GitHub Desktop
You’ve decided to use GitHub for your project. When you install GitHub Desktop, you will also get the most recent version of Git. Simply choose Download for MacOS and launch the installation. After executing the installation, run git —version in the terminal to ensure that Git was installed. You’ve completed your task!

Git Started: The Basics
Dive into Git may be intimidating. The good news is that you can get started with everything Git has to offer even if you just know a few commands. The rest will come to you as you find new requirements and seek new answers. For the time being, here are some fundamentals:
|Basic Git Commands|
|git help, git help -a, git help -g||Displays a list of Git commands and subcommands.|
|git config –global user.name “FirstName LastName”||Sets your Git username.|
|git config –global user.email “[email protected]”||Sets your Git email.|
|git init||Creates a new Git repository (repo) in the current directory.|
|git add [file/directory]||Adds snapshot of current files to the staging area (index). This does not save any work to your repository.|
|git rm||Removes files from the index.|
|git commit||Commits changes in the staging area to the repository. You must run this to save changes to your repo.|
|git commit -a||You can use this to skip using Git add. This looks for changes, adds them to staging, and commits them.|
|git diff||See changes between commits.|
|git log||See your previous commits to the repo.|
|git branch [name-of-branch]||Creates a new branch in your repository. Branches are used to split up codebases into smaller sections.|
|git branch||Lists all branches in your repo.|
|git switch [name-of-branch]||Navigate between branches.|
|git branch [name-of-branch] -d||Deletes the specified branch.|
|git clone [directory-path] [name-you-choose]||Creates a clone of the specified repository.|
|git fetch||Checks changes from another repository without integrating them to your repo.|
|git pull||Commits changes from another repository to your repo.|
|git push||Updates repo with changes for others to pull.|
Cleaning Up Your Repositories
Now that you know how to install and use Git on macOS, it’s time to start creating. Don’t be concerned about being correct or wrong, neat or sloppy. Simply try new things and learn as you go.
If, in the midst of the chaos of creation, you discover that your branches have gotten a bit too unorganized for your comfort, there are always techniques to tidy things up.
