    Getting started with Git

    who is Git?

    Git is a version control system that was created in 2005 by Linus Torvalds who was also the brainchild behind the Linux kernel. It was originally created to help manage the task of developing the linux kernel because alot of geographically distributed programmers were being involved in developing the linux system.

    Git is an open source and one of the most popular version control system with millions of projects under if’s care.

    One advantage of Git is that it is a distributed system meaning that every person contributing to a project can maintain the copy of the project they send to a common reservoir in their own development machine.

    Collaborators can share their work and be able to see what others are doing in the project anytime they need to do so. To enhance collaboration in a project, a common directory, usually refered to as the repository is setup on a server so as to act as a common point from which all participants can interact.

    Git can work as a standalone program, as a server or as a client such that you can use it offline and then you can send (push) the files you have created to the online directory once you are connected.

    You can use Git as a server on a machine where you want to host your repository and also as a client to access the repository from another machine or on the same machine.

    Git uses http,ssh or it’s own special protocols to communicate with Git servers over the network.

    Git is suitable for small projects that need one or few developers and also suitable for large project that brings together thousands of contributors. It is useful in tracking private work on personal projects but even more important, it is used to share work with others by hosting a code on public servers like Github,Gitlab and others.

    You can find more about git on git-scm.com which is the official website for Git. Git-SCM stands for Git Source Control management which is the same as Version Control System(VCS).

    One reason Git is soo popular is that it is has a multiplatform support and so it will fit in windows, macOS and linux with ease.

    Installing Git

    Git could already be installed in your computer. To check if it is already there, issue the following command:

    git --version

    To install git, you can use package management systems like:

    For windows installation, you will simply download an executable file and follow prompts. Windows installation comes with a preloaded with a MinGw64 that enables us to operate on windows with the same command and tools used on Linux.

    Version Control

    A version control is the practice of tracking and managing changes to software code. In Information Technology, we manage information across a lot of different files . The software developed must be maintained and this involves adding some new codes, deleting some, commenting some lines of code and modifying others. Other times we develop new version of the software that we expect to replace the old one.

    When changing software files, it is very important to keep detailed historical information for changes made in the file because anything can go wrong when you change a software files.

    Few weeks after you make changes, you may not have an idea what changed and so it is important to have a mechanism where you and your team can track what was modified and when incase there is need for troubleshooting.

    Version control provides a documentation trail that will let you and your team know why the infrastructure is the way it is and provides you with mechanism for undoing changes where necessary. Version Control is very hardy in software development as it helps reduce greatly the errors and bugs that maybe introduced when we change a software file.

    To avoid headaches involved in broken codes due to changes done, you can use a version control system to easily roll back your code to a version that was working before the change that caused the breakdown were done.

    Version control helps us revert our system to a particular state that was working at a particular moment.

    It is always safer to go back to a software version that had been working correctly before the change was made so as you can fix problems that occurs in changes without problems of a broken non-working systems when you are trying to solve issues. This gives you time to carefully examine the code instead of making so many quick fixes just to keep the system running.

    Version controls are crucial in maintaining healthy codebase for IT resources and for enabling many people collaborate on the same coding projects smoothly.

    Examples of version control systems includes:
