In this article, we will examine Git commands and web-based storage services that software developers prefer most in their project processes, by answering questions such as what is the Version Control System and what is Git.

What is Version Control System (VCS)?

Version Control System (VCS), also called revision control or source control. The system that records changes made to a file or set of files over time so you can recall specific versions later. Its purpose is to record each operation on the files step by step and to help us control file changes.

As many documents (software projects, documents, etc.) undergo constant changes and come together again as a result, it provides a chance to examine each of the changes that occur over time and to go back. In this way, document loss is prevented.

What is Git?

Git is among the indispensables of many software developers today. So, what is this thing we call "Git"?

Git is the most widely used, speed-oriented distributed version control and source code management system in software development processes. The first version was designed and developed by Linus Torvalds himself in 2005 for use in the development of the Linux kernel. As of 2019, it has reached a market share of 70%.

Each working directory (project) using the Git version control system is a fully authorized repository that holds the entire history and contains the entire version control system, without internet access or a central repository. Changes to a copy of the same working directory in one of many repositories are accepted on a trust-based assessment of the others. No changes are received from the untrusted, it continues to develop its own standalone version.

Git Commands

In order to use the Git system, we need to learn what the commands do. So, we have compiled the commands most used by today's software developers under 5 headings.

1) The following git commands must be used to submit your projects or documents to web storage services.

git config: Used to set configs after Git installation.

git init: It is used to create a local repository on the computer.

git add: It is used to add the selected documents to the local repository.

git commit: It is used to add the documents to be added to the local repository with comments.

git remote: It is used to determine the remote server address to which we will upload our documents.

git push: It is used to send the files in the local repository to the repository on the remote server.

2) Branching and merging operations are generally used when more than one person works in the projects. To perform these operations, different git commands must be used. We have compiled these for you

git branch: It is used to create branches.

git checkout: Used to switch to any previously created Branch.

git merge: It is used to merge the branches created.

git rebase: It works similarly to the "git merge" command. But it leaves no record of branching behind.

3) If we want to copy a project from the remote repository to our computer and undo the transaction after committing the documents, the following Git commands should be used.

git clone: It is used to copy the documents on the remote server to your computer.

git revert: Used to undo any committed changes.

git reset: It is similar to the “git revert” command, but when you run this code, the last commit you sent is deleted.

Best Git Repositories

GitHub is the largest and most popular code hosting service since 2008. It helps developers to store and manage their code and monitor and control changes in their code. GitHub's interface is user-friendly and easy for beginners. Using Git without GitHub usually requires more technical knowledge and more command line usage.

GitLab is very similar in principle to GitHub. For this reason, the best way to understand GitLab is to describe the difference between GitHub and GitHub. Compared to GitHub, GitLab includes options such as code continuity, unlimited code repository, and unlimited disk space. GitLab allows you to keep your codes on remote servers as private or public for free through Git. In short, we can say that GitLab is the open-source sharing interface version of GitHub.

Since we defined GitLab by comparing it with GitHub, then it would not be wrong to define Bitbucket with its features that distinguish it from GitLab. GitLab only supports Git repositories, while Bitbucket offers support for both Git and Mercurial. If you're using Mercurial or other repositories, switching to GitLab can be a bit complicated. Fortunately, GitLab is equipped with a repository import feature that helps users easily migrate from other platforms. Bitbucket also supports SVN, Google Code, CodePlex, HG and SourceForge as well as repository importing from Git.
