Git is an open source version control system that helps track and manage changes to code over time. It is classified as a distributed version control system (DVCS), meaning that it stores and tracks versions of code across multiple devices, rather than in a central location.
Git allows developers to easily undo changes, view the evolution of a project, and collaborate with others on code development.
Other version control systems include CVS, SVN, Mercurial, and Fossil, but Git is widely considered to be a leading tool in the field of source code management (SCM).

With Git, 3 basic issues were solved when working on projects:
- Collaboration: Git allows multiple developers to work on the same project simultaneously without overwriting each other's changes. This makes it easy to collaborate on code development and share work with others.
- Version control: Git keeps track of every change made to a project, allowing developers to easily roll back to previous versions if needed. This helps prevent lost work and makes it easier to identify and fix issues.
- Backups: Git stores copies of every version of a project, providing a reliable backup system in case of data loss or corruption. This helps ensure that important work is not lost and can be recovered if necessary.
Files in a repository go through three stages before being under version control with git:
Yes, that's correct. In Git, files go through three stages before being considered under version control:
- Unmodified: This is the state of a file when it has not been modified since it was last checked out from the repository or last committed.
- Modified: This is the state of a file when it has been modified, but the changes have not been committed to the repository.
- Staged: This is the state of a file when it has been modified and the changes have been marked to be included in the next commit.
To move a file from the unmodified stage to the staged stage, you can use the git add command. To move a file from the modified stage to the staged stage, you can use the git add command with the -u flag. Finally, to commit the staged changes to the repository, you can use the git commit command.
There are several reasons why Git has become the most popular version control system (VCS) and source code management (SCM) tool:
- Distributed version control: Git is a distributed VCS, which means that developers can work locally and commit their changes to a local repository, without the need for a central server. This makes it faster and more efficient for teams to work on large projects.
- Speed: Git is designed to be very fast, even when working with large repositories. This is because it stores data as snapshots, rather than as a series of changes.
- Non-linear development: Git allows developers to create multiple branches for their work, which can be merged together later. This makes it easy to experiment with new ideas and collaborate with others.
- Open source: Git is open source software, which means that it is free to use and distribute. This has helped to contribute to its popularity and widespread adoption.
- Strong community: Git has a large and active community of users and developers, who contribute to the development of the software and provide support to others.
Overall, Git's combination of distributed version control, speed, non-linear development, open source nature, and strong community make it a powerful and popular tool for revision control and SCM.
Git uses some repositories management services like Github, Gitlab, Bitbucket etc.
GitHub:
GitHub is a web-based platform for hosting and collaborating on software projects. It is built on top of the Git version control system, and it is one of the most popular platforms for hosting and sharing code. Some key features of GitHub include:
- Code repositories: GitHub provides a place to store, manage, and track code repositories. It supports Git and Subversion.
- Collaboration tools: GitHub provides tools for team collaboration, including code review, issue tracking, and wikis.
- Continuous integration: GitHub integrates with popular continuous integration tools such as Jenkins and Travis CI, allowing developers to automate the build, test, and deployment process.
- Security: GitHub includes features to help developers secure their code, including access controls and two-factor authentication.
- Scalability: GitHub can be used by small teams or large enterprises, with support for thousands of users and millions of repositories.
Some pros of using GitHub include:
- It is a comprehensive tool that provides many features for managing code repositories, collaborating with teams, and automating the development process.
- It has a large and active community of users and developers, which makes it a good place to find and contribute to open source projects.
- It integrates with other tools and services, such as Slack and Trello.
Although GitHub does not have a built-in feature for scheduling jobs using Cron syntax, it is still possible to automate tasks such as running backups, checking the status of servers, or triggering builds. This can be done using a third-party tool or a service like AWS Lambda.
These tools and services allow you to schedule tasks to run at specific intervals using Cron syntax, which can be useful for automating various tasks related to your GitHub repositories.
GitLab:
GitLab is a web-based Git repository manager that provides source code management (SCM), continuous integration, and more. Some key features of GitLab include:
- Code repositories: GitLab provides a place to store, manage, and track code repositories. It supports both Git and Subversion.
- Collaboration tools: GitLab provides tools for team collaboration, including code review, issue tracking, and wikis.
- Continuous integration: GitLab includes built-in continuous integration and deployment tools, which allow developers to automate the build, test, and deployment process.
- Security: GitLab includes features to help developers secure their code, including access controls, two-factor authentication, and code scanning.
- Scalability: GitLab can be used by small teams or large enterprises, with support for thousands of users and millions of repositories.
Some pros of using GitLab include:
- It is a comprehensive tool that provides many features for managing code repositories, collaborating with teams, and automating the development process.
- It is open source, which means that it is free to use and modify.
- It has a strong community of users and developers who contribute to the software and provide support.
As for crons, GitLab allows you to create and schedule jobs using Cron syntax. This can be used to automate tasks such as running backups, checking the status of your servers, or triggering builds. You can create a Cron job by navigating to the "CI/CD" settings of your project and creating a new "Scheduled Pipeline." You can then specify the Cron syntax for when you want the job to run.
BitBucket:
Bitbucket is a web-based version control repository hosting service owned by Atlassian, used for source code and development projects that use either Mercurial (since launch) or Git (since October 2011) revision control systems. Some key features of Bitbucket include:
- Code repositories: Bitbucket provides a place to store, manage, and track code repositories. It supports both Git and Mercurial.
- Collaboration tools: Bitbucket provides tools for team collaboration, including code review, issue tracking, and wikis.
- Continuous integration: Bitbucket integrates with popular continuous integration tools such as Jenkins and Bamboo, allowing developers to automate the build, test, and deployment process.
- Security: Bitbucket includes features to help developers secure their code, including access controls, two-factor authentication, and IP whitelisting.
- Scalability: Bitbucket can be used by small teams or large enterprises, with support for thousands of users and millions of repositories.
Some pros of using Bitbucket include:
- It is a comprehensive tool that provides many features for managing code repositories, collaborating with teams, and automating the development process.
- It integrates with other tools in the Atlassian ecosystem, such as Jira and Trello.
- It has a strong community of users and developers who contribute to the software and provide support.
As for crons, Bitbucket does not have a built-in feature for creating and scheduling jobs using Cron syntax. However, you can use a third-party tool or a service like AWS Lambda to automate tasks such as running backups, checking the status of your servers, or triggering builds.
