<h2>Git and the Command Line: Basics and Installation</h2>
<h2>What Is Git?</h2>
<p>Git is a powerful version control system designed to track changes in files and facilitate collaboration among developers. Created by Linus Torvalds for the Linux kernel, Git has since become widely adopted for managing code across various types of projects. Git and Command Line tools are essential for effectively leveraging Git’s capabilities, allowing users to maintain a history of changes, revert to earlier versions, and manage multiple versions of a project at once.</p>
<p>At its core, Git tracks changes to files in a directory, enabling users to save different versions of their work. This is especially valuable in collaborative environments where multiple developers may be working on the same codebase, helping to prevent conflicts and ensure alignment on the project&#8217;s progress. For a deeper understanding, <a href="https://cloudastra.co/blogs/demystifying-git-how-it-really-works">Demystifying Git: How It Really Works</a> explores the mechanisms behind Git, clarifying its operations and practical applications.</p>

<h2>The Graphical User Interface and the Command Line</h2>
<p>Git can be used with graphical user interfaces (GUIs), but the command line interface (CLI) remains the most powerful and versatile way to interact with it. GUIs offer a more visual approach, which may be easier for beginners, but the command line provides full access to Git&#8217;s features and is essential for understanding how Git operates behind the scenes.</p>
<p>Using the command line, you can execute commands to manage your repositories, track changes, and perform other Git operations. By becoming familiar with the CLI, you gain a deeper understanding of how Git works.</p>
<h2>Opening a Command Line Window</h2>
<p>To get started with Git, you need to open a command line window. The specific application will depend on your operating system:</p>
<ul>
<li><strong>macOS</strong>: Open the Terminal application.</li>
<li><strong>Windows</strong>: Use Git Bash, a terminal emulator that provides a Unix-like command line experience.</li>
</ul>
<p>The command line window will display a prompt indicating your current directory, which is where you’ll execute your Git and Command Line. By default, the starting point is often your home directory (<code>~</code>).</p>
<h2>Executing Commands in the Command Line</h2>
<p>Once your command line window is open, you can start typing commands. Some basic commands to get familiar with are:</p>
<ul>
<li><code>pwd</code>: Displays the current directory path.</li>
<li><code>ls</code>: Lists the files and directories in the current directory.</li>
<li><code>cd &lt;directory_name&gt;</code>: Changes the current directory to the specified one.</li>
<li><code>mkdir &lt;directory_name&gt;</code>: Creates a new directory.</li>
</ul>
<p>These commands help you navigate your file system and set up your workspace to use Git.</p>
<h2>Installing Git</h2>
<p>Before using Git, you must install it on your computer. The installation process varies by operating system:</p>
<ul>
<li>
<p><strong>macOS</strong>: Install Git via Homebrew by running <code>brew install git</code>, or download the official installer from the <a href="https://git-scm.com/downloads" target="_new" rel="noopener">Git website</a>.</p>
</li>
<li>
<p><strong>Windows</strong>: Download and install Git for Windows from the <a href="https://git-scm.com/downloads" target="_new" rel="noopener">Git website</a>.</p>
</li>
<li>
<p><strong>Linux</strong>: Git is often pre-installed, but if needed, install it using your package manager, such as <code>sudo apt-get install git</code> on Ubuntu.</p>
</li>
</ul>
<p>To verify installation, run <code>git --version</code> in the command line to confirm the Git version installed.</p>
<h2>Command Options and Arguments</h2>
<p>Git and Command Line commands often include options (which modify the behavior of the command) and arguments (which specify the target of the command). For example, in <code>git commit -m "Initial commit"</code>, <code>-m</code> is an option, and <code>"Initial commit"</code> is an argument.</p>
<p>To explore any Git command, use <code>git &lt;command&gt; --help</code> to access detailed documentation on its usage.</p>
<h2>Clearing the Command Line</h2>
<p>To maintain a clean workspace, clear the command line screen using:</p>
<ul>
<li><code>clear</code> on macOS and Linux.</li>
<li><code>cls</code> on Windows.</li>
</ul>
<p>This will help you avoid clutter as you execute more commands.</p>
<h2>Opening the Filesystem Window</h2>
<p>Although the command line is powerful, sometimes it&#8217;s easier to navigate files visually. While working with Git and Command Line, you can open your file explorer (Finder on macOS, File Explorer on Windows) to view and manage files outside the command line interface.</p>
<h2>Working with Directories</h2>
<p>Efficient directory management is crucial when using Git. Here are some useful directory commands:</p>
<ul>
<li><code>cd ..</code>: Moves up one directory level.</li>
<li><code>cd -</code>: Switches back to the previous directory.</li>
<li><code>mkdir &lt;directory_name&gt;</code>: Creates a new directory.</li>
<li><code>rmdir &lt;directory_name&gt;</code>: Removes an empty directory.</li>
</ul>
<p>These commands help keep your project organized.</p>
<h2>Closing the Command Line</h2>
<p>To exit the command line:</p>
<ul>
<li>On macOS, close the Terminal window.</li>
<li>On Windows, type <code>exit</code> and press Enter in Git Bash to close the terminal.</li>
</ul>
<h2>Setting Git Configurations</h2>
<p>Before starting with Git, it&#8217;s important to configure your user information. This ensures that your commits are correctly attributed. Set your name and email globally using:</p>
<div class="contain-inline-size rounded-md border-[0.5px] border-token-border-medium relative bg-token-sidebar-surface-primary dark:bg-gray-950">
<div class="flex items-center text-token-text-secondary px-4 py-2 text-xs font-sans justify-between rounded-t-md h-9 bg-token-sidebar-surface-primary dark:bg-token-main-surface-secondary select-none">bash</div>
<div class="sticky top-9 md:top-[5.75rem]">
<div class="absolute bottom-0 right-2 flex h-9 items-center">
<div class="flex items-center rounded bg-token-sidebar-surface-primary px-2 font-sans text-xs text-token-text-secondary dark:bg-token-main-surface-secondary"><span class="" data-state="closed"><button class="flex gap-1 items-center select-none py-1">Copy code</button></span></div>
</div>
</div>
<div class="overflow-y-auto p-4" dir="ltr"><code class="!whitespace-pre hljs language-bash">git config --global user.name <span class="hljs-string">"Your Name"</span><br />
git config --global user.email <span class="hljs-string">"you@example.com"</span><br />
</code></div>
</div>
<p>Verify your configuration settings with:</p>
<div class="contain-inline-size rounded-md border-[0.5px] border-token-border-medium relative bg-token-sidebar-surface-primary dark:bg-gray-950">
<div class="flex items-center text-token-text-secondary px-4 py-2 text-xs font-sans justify-between rounded-t-md h-9 bg-token-sidebar-surface-primary dark:bg-token-main-surface-secondary select-none">bash</div>
<div class="sticky top-9 md:top-[5.75rem]">
<div class="absolute bottom-0 right-2 flex h-9 items-center">
<div class="flex items-center rounded bg-token-sidebar-surface-primary px-2 font-sans text-xs text-token-text-secondary dark:bg-token-main-surface-secondary"><span class="" data-state="closed"><button class="flex gap-1 items-center select-none py-1">Copy code</button></span></div>
</div>
</div>
<div class="overflow-y-auto p-4" dir="ltr"><code class="!whitespace-pre hljs language-bash">git config --global --list<br />
</code></div>
</div>
<p>This command will display your Git configuration.</p>
<h2>Preparing a Text Editor</h2>
<p>A text editor is essential for working with code in Git. Popular editors for coding include:</p>
<ul>
<li><strong>Visual Studio Code</strong>: A versatile editor with Git integration.</li>
<li><strong>Sublime Text</strong>: A fast, lightweight editor with a clean interface.</li>
<li><strong>Atom</strong>: An open-source text editor developed by GitHub.</li>
</ul>
<p>Choose an editor that suits your needs and preferences.</p>
<h2>Integrated Terminals</h2>
<p>Many modern text editors, such as Visual Studio Code, feature integrated terminals. This allows you to run Git and Command Line commands directly within the editor, streamlining your workflow. In Visual Studio Code, open the integrated terminal by going to <code>View &gt; Terminal</code> or using the shortcut <code>Ctrl + `</code>.</p>
