Getting Started with Git Bash: A Step-by-Step Guide.

INTRODUCTION TO GIT BASH
Git Bash is a powerful command-line interface that brings the flexibilty and functionality of Unix-like terminals to Windows. It's very easy to run coommands on the terminal like on the Linux and macOS. Whether you are a new developer or a seasoned developer,Git bash is an essential tool for managing version control, automating tasks, and streamlining your workflow.

Understanding Linux commands is crucial for web developers because many web servers run on Linux, and using command line is often the fastest and most precise way to manage and interact with these systems.

Git bash is built because of windows users, to have commands that works on the Linux and macOS work on windows as well.

Terminal Differences: Linux, macOS, and Windows

Linux and macOS:

● Both Linux and macOS are Unix-based operating systems, which means their terminals
(the command line interface) are very similar.
● In both systems, you can access the terminal by simply searching for "Terminal" in your
applications.
● The command syntax and utilities available in the terminal are quite consistent between
Linux and macOS, making it easier to transfer skills between these systems.

Windows:

● Windows originally used Command Prompt (cmd.exe) and later introduced PowerShell,
a more advanced shell with scripting capabilities.
● Unlike Linux and macOS, Windows is not Unix-based, which means its native
command-line tools and syntax are different.
● However, for consistency with Unix-based systems (like the servers you'll work with), it's
recommended to use Git Bash on Windows.

Why use Git Bash on windows?

Git Bash provides a terminal environment that emulates a Unix shell,providing similar experience to Linux and macOS terminals. These are several reasons:

1. Consistency Across Platforms:You can use same syntax and commands that you use for both Linux and macOS.
2. Access to Git and Linux Commands:Git bash comes with commands like ls, cd, pwdand grep, which are not available o command prompt.
3. Easier for Web Development:When setting up your development environment, Git bash helps ensure compatibility and reduces friction.
