Git Mastery: Unlock Efficiency with this Comprehensive Guide to Version Control
While technically optional, incorporating version control is deemed practically essential by seasoned software developers. This practice involves placing our application source code under version control systems, providing the ability to track changes, collaborate seamlessly, and recover from inadvertent errors. Proficiency in version control is considered a requisite skill for any professional-grade software developer.
Although various version control options exist, the software development community has overwhelmingly embraced Git, a distributed version control system initially developed by Linus Torvalds for the Linux kernel. Putting your source code under version control with Git is not only a widespread practice in the Rails world but is also highly recommended. This approach facilitates easier backup, code sharing, and application deployment, making it a valuable asset for every developer.

Git setup: First-time system setup
Prior to delving into Git, there are a few one-time setup procedures you need to undertake. These system configurations are performed only once for each computer. The initial and mandatory step involves configuring your name and email address.
git config --global user.name "Your Name" git config --global user.email "your@email.com"
Keep in mind that the name and email address you set in your Git configuration will be visible in any public repositories you create.
Consider setting up Git's default branch as part of your configuration process.
git config --global init.defaultBranch main
Moving forward, let's consider an optional yet convenient action: establishing an alias, or synonym, for the frequently used checkout command.
git config --global alias.co checkout
In this guide, I will consistently employ the complete 'git checkout' command for optimal compatibility. However, in practical scenarios, I often utilize 'git co' for brevity.
The last essential step involves eliminating the need for Git to request your authentication credentials each time you execute commands like push or pull. The methods to achieve this vary depending on your system. For Linux users, a straightforward approach is to set a cache timeout, as demonstrated below.
git config --global credential.helper "cache --timeout=86400"
The configuration above instructs Git to store passwords for 86,400 seconds (equivalent to one day). For those prioritizing security, opting for a shorter timeout, such as the default 900 seconds or 15 minutes, is recommended.
