It is no secret to anyone that the first decade of the 21st century was one of the most important turning points in the history of technology and communication. The expansion of the Internet, the promise of smartphone production, the introduction of the iPhone, the emergence of Facebook, the leadership of Google and Microsoft, the creation of Bitcoin, etc., were perhaps the most important events that we witnessed in this decade.

In these years, the world of programming was also faced with interesting and impactful events. It was in 2005 that the Linux staff succeeded in creating Git while working on the Linux kernel project and just when the bitkeeper resource control system was used to maintain and manage the project’s code.

In those years, Linux Torvalds was looking for a system that he could use to manage the project like Bitkeeper, and one year later, on June 16, 2006, he was able to manage the 2.6.12 kernel release using Git.

Git is an abandoned word in English and it means a person who is born to harass others. Unpleasant and sticky! But this unpleasant creature could become one of the most essential tools needed by developers and programmers in a very short time.

What is Git?

If you are going to work on a project, you may want to monitor changes made by other developers, see bugs and features one by one, and manage the project as a whole.

Git is a version control system that developers around the world can use and collaborate with other developers.

Although Git itself can seem like a complicated topic, I am trying to introduce you to the main and fundamental concepts of Git in the simplest way in this article, so that you can use it as much as possible in the way of learning programming.

Version control systems store developers’ changes and revisions in a central repository.

This makes collaboration between developers easy; in this way, any developer can download the new version, apply changes to it and then upload it. On the other hand, all developers will be able to see the new changes, download them and participate in the project.

The importance of learning Git

Git helps you to be less confused in the progress of a project and to be able to manage it well after its completion. The main difference between Git and other VCS is that Git’s way of thinking and its user experience are completely different from other systems such as subversion, CVS or performance, although there may be similarities between them in terms of user interface.

Applications of Git

  • Ability to make changes and provide description of changes in a list
  • Update in local repository and merge it remotely with another branch
  • Suitable for projects that more than one person works on and creating interaction between members in group projects
  • Ability to add tags to any software version
  • Presenting the history and the possibility of studying and checking the historical records of the reservoir
  • Ability to replace changes and restore previous codes in case of problems in the repository

Git Repositories

Git control system is available to developers completely free of charge through web applications such as github and gitlab. The advantage of these systems is that when you put your source codes in them, you will no longer have to worry about losing your source codes.

Also, you will be able to define different projects and access levels on these websites and keep multiple copies of projects.

And the most important Git repositories:

  • GitHub: Launched in 2008 and recently acquired by Microsoft. In the fall of 2017, it had about 31 million users.
  • GitLab: It was launched in 2011 and is owned by GitLab.
  • BitBucket: It was launched in June 2008 and is owned by the software company Atlassian.
